i know this is a just a thing for fun but i feel the need to pointt out q.20 is incorrect q20 'what is the term for the ammount of matter in an object' the correct answer here should be mass defind by its volume ..an object haave mass, but its defined by its volume... so the correct answer as the question is asked is Volume say we have an object a solid ball... it has a volume that defines the boundaries of the object regardless of what mattter it is made of. q22 a general misconception is that the suns core is the Hoittest part of the sun (even among scientists), it isent, its outside the core, in general we call it the corona... (but it isent quite right it inbetween)... but for fun trivia (without the science) the core is an acceptable answer... q44 'what is the only element without neutrons in its nucleus' about 99.985% have just a single Proton (H-1), and other isotopes can have one or more Neutrons.. the quetsion should ask what element normally... q73 'who famously used a prism to demonstrate that white light is made of different colours' ..most likely Ptolomy over 2000 years ago (who also wrothe 5 books on light, lenses etc, of one survived till today), the mathematical proof was made by Roger Bacon in 13th century (but he couldent experimentally prove it), its clearly show he knew 'light' was made of different waveneghts (colours)... q80 'what causes the earth to have seasons' the correct answed should be its orbit around the sun in combination with its tilt, explanation: it the Earh was just tilted but stationary only difference in short wetherpatterns would exist (day and night), earths orbitt around the sun it was what causes the season (the axis tilt to or from the sun at extremes (winter - summer) q85 'what is the process of a cell dividing in two identical daughter cells called' correct answer is Cytokinesis (wich Mitosis is a step of, splicing of the DNA molecule)

@@Patrik6920 Thanks for commenting. Mass is a measure of the amount of matter in an object. There are many references to this. The hottest part of the sun is definitely the core, again, many references. The Earth's tilt causes the seasons, it has nothing to do with the orbit. This can be confirmed by the fact that it is closest to the sun in January, yet it is winter in the Northern Hemisphere in January. Again there are many references that confirm it is due to the tilt. Anyway, thanks for commenting, its always great to discuss these things.

@KenFullman 3 ай бұрын

I have to be pedantic about Q60. "What happens to the speed of light when it travels through water?" Now you say "it slows down" but that's not right. Light travels at a constant speed through water. That constant speed is slower than when travelling through a vaccuum or the air, but while it's travelling through the water it is still travelling at a constant speed. Now even if you'd said "What happens to the speed of light as it ENTERS water?" You'd have been closer to correct but still not quite right because it depends what medium the light is entering the water FROM. If light was to enter water from a diamond, it would actually speed up.

№47 is not correct either. The reason for hot air rising is that it is not as dense as cold air. Cold air is denser (i.e. heavier per volume unit) and dense liquids, gases tend to drift lower, pushing other liquids/gases, up. So the reason is "different density". "Convection" is a consequence of this process.

@evil17 3 ай бұрын

Your argument sounds fair & I had to think about this one for a bit, because isn’t “Cold” a term we have given to a body that lacks relative heat, ie: there is no such thing as cold, just a lack of heat. A heated substance will have more energy and tend to rise and causes motion even at an atomic level, heat causes more motion (heat is a body/or energy that is in constant motion) & so a convection of currents can/will occur as the heat continues to move from a warmer body to a cooler body until it reaches an equilibrium. Hot water system can be interesting in this way, thats a solar HW system will have it’s tank above the solar collector panels so the cooler water circulates by convection to the panels for heating which creates a convection cycle, whereas a electric HW system tank will introduce the cold water (usually) down low of the tank as the hot water exits the upper tank level & there will be a definite line where the cold and hot water is until it reheats the whole tank again by way of a heating element down low which will cause a convection of currents to heat the whole tank, but what happens if the heating element blows while the tank is half hot & half cold & left that way with no water in or out, without a pump to move the water inside the heat would slowly move down to the lower cooler water, but this would take some time and I dont know if it could be called convection in such an instance where the cooler water is just slowly absorbing the heat from the hotter water source above it and not really setting up a convection of currents. IDK just guessing.

@mehdimarashi1736 3 ай бұрын

@@evil17 "A heated substance will have more energy and tend to rise and causes motion even at an atomic level, heat causes more motion" Be very careful here, the heated air rises only because it has a lower density. The warm air body "floats" in the ocean of cold air and rises up, because its weigh is less than the Archimedes' force exerted on it by the ocean of the cold air. Heat is motion, motion is not heat. The energy of rising hot air (upward velocity) is kinetic energy, not heat. "a convection of currents can/will occur as the heat continues to move from a warmer body to a cooler body until it reaches an equilibrium." Most heat transfer between the hot and cold air "bodies" happens because of these bodies mixing together on the boundaries. It is hard to talk about a "body" that does not have a well defined boundary. Another thing to consider: if the warm air body is above the cold body, there is no reason for any movement, so, while the heat transfer is in progress from the warm to the cold body, no movement happens and there is no convection. So, it's not the temperature difference that causes the convection. It's the difference in the specific weight of the bodies, which makes the lighter body to float in the denser fluid.

92/100. I disagree that it's composition that distinguishes asteroids from comets, virtually all of the asteroids in the outer solar system - the Trojans, Kuiper belt objects, are largely composed of ices, and would be comets if in highly elliptical orbits that entered the inner solar system.

@rogerarnold5627 3 ай бұрын

There was a recent science news item about the difference between between asteroids and comets. The thinking is tilting to the view that asteroids and comets are pretty much the same, in terms of their compositions at the time the solar system was forming. But asteroids were in closer orbits, and most of their volatile components -- ice and frozen gasses -- have been driven off over the eons. Also, orbiting in the much more crowded inner parts of the solar system, they've been subject to reforming by collisions and agglomeration. But there's been found to be a continuum of objects between "typical asteroid" and "typical comet". So it's their orbit that distinguishes them in a more fundamental sense than composition. Although their orbit does affect their composition over time.

@andrewworth7574 3 ай бұрын

@rogerarnold5627 I suspect that the line of reasoning that leads to the claim that its composition that counts rather than orbit is: What makes a comet a comet? It has volatiles that produce the coma and tail, an asteroid in the same orbit doesn't have the coma and tail because it has few volatiles, therefore the difference between a comet and asteroid is the composition. The problem with that reasoning is that it eliminates from consideration all the volatile containing asteroids not in the orbits that make any volatiles sublimate.

@@mauricearpin7946 The Asteroid-Comet Continuum: In Search of Lost Primitivity By Matthieu Gounelle "Recent results from the Stardust comet sample-return mission have confirmed the idea that there is a continuum between primitive small bodies in the outer main asteroid belt and comets. Indeed, the mineralogy as well as the chemical and oxygen isotope compositions of the dust from comet Wild 2 are very similar to those of carbonaceous chondrites, a class of meteorites allegedly derived from primitive, dark asteroids. Comets no longer represent extremely primitive samples of the early Solar System that are radically different from dark asteroids. We enter a new era in which comets and their siblings, the dark asteroids, are seen as a collection of individual objects whose geology can be studied"

Still, I aced the quiz with 100/100 and no mistakes. It must be my "neuroplasticity." 😅The biology questions were easier with the multiple-choice options. But I didn’t need them for physics. I remembered that Rayleigh’s scattering makes the sky blue and diffraction bends light through water (we did experiments on these things). I guessed the gymnosperm question, though. Your clue about the corn on the cob helped. I knew it was a seed. I also knew that sulfur compounds are not common on planets like Mars. I’m so happy with my quiz results. And I feel smarter too. Mechanical engineering is the best education you can get. That stream develops the strongest analytical skills that stay with you your whole life. 😅

Q38 - I think the term "powerhouse" is too general and ambiguous, so that "nucleus" would also have been a correct answer. Even though mitochondria are often referred to as the "powerhouse" of the cell, this is not a strictly scientific definition. It would have been clearer to have asked "what part or parts of a cell generate the energy needed to power the cell?" rather than relying on people getting the right meaning of the word "powerhouse".

92/100 ... I too had a little issue with No 47 feeling that Archimedes was more fundamental and convection was a process - but I looked it up after and convection is totally the right answer. I also worried a bit about the asteroid/ comet one feeling that the orbit was the more important - but I looked that up as well and am now very happy that composition is a good answer. A most enjoyable quiz.

Question 60: The speed of light never changes, it's always the same. It only appears to go slower, because it takes a longer path.

@williambavington5392 18 күн бұрын

That is true in general relativity, a light ray follows a geodesic path in curved space-time near a body with mass. However, light travels more slowly through a medium because the relative electric permittivity and relative magnetic permeability are greater than unity and the speed of light in any medium is given by c= 1/sqrt(epsilon times mu).

⁠@@Quizzes4Uslows down is completely fine, esp. if you think maxwells equations in media are good and they are. Any reference to a photons is suspect, since a light wave doesn’t even have a fixed number of photons (see Glauber state), and single photon slows down and the speeds back up on the exit….but is you say it’s moving at c but interfering with phase shifted versions of itself, then is it really the same photon, or a coherent copy of the original? idk, why get into quantum mechanics…just say it slows down, or not. If you look at it classically with jefimenkos equation, then a wave doesn’t have an identity, it’s just an emergent phenomenon related to charges and currents😊 in the pas lightcone…so agin, it’s coherent new wave.

Questions no. 47 is worded wrong. Convection IS the movement of fluids due to different properties, like density. It doesn't explain why it happens. Archimedes explains that warm air, being less dense as it expanded, rises above colder, denser air because it displaces more volume per unit of mass.

@nicholasharvey1232 3 ай бұрын

I guessed Archimedes on this as well. I knew Archimedes had a law of buoyancy, and warm air rising above cooler air IS an example of buoyancy, because the warm air is less dense. Just as something less dense than water (or other fluid) will float to the top.

Only in a vacuum is it at the speed of light in vacuo quoted in all the textbooks. The speed of light depends upon the electric permittivity (epsilon) and magnetic permeability (mu) of the medium it is travelling in. c = 1/sqrt(epsilon times mu) You can derive that from Maxwell's equations of electromagnetism so light always travels more slowly in any medium than in a vacuum. Even in air is travels about 1% slower if I remember correctly.

"What is the term for the amount of matter in an object?". It is neither volume, density or mass.

The term you are asking for is simply "amount" and is measured in mol.

The amount of matter is measured in mass. 1 mol of carbon (12 grams) has a different mass than 1 mol of sodium (23 grams). This is because sodium has more matter (protons, neutrons, and electrons) than does carbon. Mass truly is measuring the amount of matter - protons, neutrons, and electrons that make up the atoms.

Although Cryogenics specifically focuses on the effects of low or ultra low temperatures on matter, quantum mechanics and a big area of quantum physics is literally impossible to study without using temperatures near the absolute zero range because at those low temperatures phenomena are more easily observed or statistically possible to occur.

Frequency * wavelength equals the speed of the wave for radio and light that means frequency times the wavelength equals the speed of light.

5. "What is the branch of physics that deals with the behavior of objects at very low temperatures?" A. Cryogenics B. Quantum mechanics C. Thermodynamics It's all three, by definition. Obviously the "very low temperatures" bit was meant to guide people to answer Cryogenics, and if you get literal enough the other two branches don't deal exclusively with cold temperatures, but the whole reason of studying the behavior of objects at very low temperatures involves quantum mechanics (e.g. Bose-Einstein condensates), and you literally can't do low-temperature physics without considering thermodynamics.

I'll quibble with three: convection is the dynamic process, while Archimedes' principle, differential buoyancy, is the mechanism; light slows at the transition to water from vacuum or air, once within a medium it travels at the speed of light for that medium; and I'd say that an ice object or stony/metallic object can sit happily in a more or less circular orbit (low eccentricity) until some destabilizing interaction launches it towards fair 'helios' where the icy object (maybe sandy dune) grows its characteristic cometary plume(s).

Nice mix of questions. Just a suggestion for improvement: I know you are trying to ask the questions in an uncomplicated way but the wording of the question about a falling object (q19) is technically incorrect. An object in freefall does not suddenly reach terminal velocity. Depending on its surface area and density, a falling object may only experience true freefall for the first 4 seconds. After that air resistance steadily increases until it equals and balances the weight of the object. At this point it reaches terminal velocity and continues in this state until it hits the ground. Possible better wording (correct but straight-forward): If an object falls from a great height to the Earth (even without contact with a rope or surface) it will eventually reach a state of constant speed. What do we call this constant speed? (Very wordy - maybe someone can streamline)
