Transcripts
Slide 1

Week 4 (10/09) – Quiz #4 Which of the accompanying explanations is TRUE Studies of the Cosmic Microwave Background Radiation permit us to test the Universe\'s properties the distance back to Big Bang Galaxy impacts are normally joined by crashes between individual stars Kepler’s first law lets us know that the circle of every planet in the Solar System is an impeccable oval with the Sun at the focal point of the oval The aggregate mass of the Milky Way world is 10 11 kilograms Most of the matter in the Universe is in a non-brilliant shape however makes its vicinity felt through its gravity

Slide 2

Week 4 (10/09) – Quiz #5 Which of the accompanying proclamations is FALSE The solid and feeble atomic strengths are short-range compels that don\'t comply with the reverse square law The power of contact is a case of the electromagnetic power Gravity is the essential power having an effect on everything amid the arrangement of cosmic systems There are five principal powers in Nature The atomic combination responses that power the Sun include the solid atomic power

Slide 3

Week 4 (10/11) – Quiz #6 Which of the accompanying “Scientist: Fact” affiliations is the LEAST DIRECT ? Maxwell: Wave nature of electromagnetic radiation Kepler: The Sun circles the Milky Way’s focus Newton: Laws of gravity Einstein: Particle nature of electromagnetic radiation Kelvin: The movement of atoms stops at outright zero

Slide 4

Week 4 (10/11) – Quiz #7 Which of the accompanying explanations is FALSE ? Einstein demonstrated that the molecule way of electromagnetic radiation can clarify the photoelectric impact and was granted the Nobel Prize for this Each gamma-beam photon is more lively than a radio photon and every wellspring of gamma beams is a larger number of iridescent than a radio source One of the segments of the electromagnetic range where the environment is straightforward (“windows”) nearly coordinates the bit to which the human eye is delicate and this likely come about because of Darwinian advancement Scientists have specifically measured the little vacillations in the Cosmic Microwave Background Radiation that speak to the “seeds” from which worlds and groups of systems shaped When you take a gander at the understudy sitting alongside you, you are viably considering them to be they were a small amount of a second before

Slide 5

Week 4 (10/13) – Quiz #8 Star X has a surface temperature that is 3 times higher than that of the Sun. Both stars have the very same span. Which of the accompanying proclamations is TRUE ? The Sun\'s radiance is 81 times that of the star X The average photon discharged by star X has a lower vitality than the run of the mill photon transmitted by the Sun Star X is rosy in shading while the Sun is yellowish white If both stars were at the same separation from us, the Sun would show up 81 times fainter than star X Most of the vitality of star X is radiated at a more drawn out wavelength than the vast majority of the Sun’s vitality

Slide 6

Week 4 (10/13) – Quiz #9 Which of the accompanying proclamations is FALSE : Kepler’s first law expresses that the circle of every planet in our Solar System is an oval with the Sun situated at one of the oval\'s foci We live in a growing Universe, but it is hard to locate a parking spot on this grounds! Electrons inside of molecules can have one of numerous conceivable discrete vitality levels Astronomy and astronomy bargain principally with telling a person’s future from the planets\' positions Einstein suggested that mass can be changed over into vitality and the other way around

Slide 7

Week 4 (10/13) – Quiz #10 Which of the accompanying articulations is TRUE : The Moon is made of green cheddar and the first space travelers who arrived on the Moon found this exceptionally heavenly actuality The wave-molecule duality of electromagnetic radiation alludes to the way that it can be depicted as a wave and/or as parcels or packs of vitality known as “photons” Wavelength is specifically corresponding to recurrence on account of electromagnetic radiation The glow of a dark body is relative to the square of its surface zone The opposite square law expresses that the flux from a star is contrarily relative to the fourt
