QUESTION 43
X-rays have shorter wavelength than visible light; therefore, X-rays ________.
have lower energy than light waves
are higher energy than light waves
pass through materials because their photons are smaller than light photons
cannot be detected because of their wavelength
very large impact craters filled with basaltic lava
remnant highlands produced from a time when the moon was entirely molten
large lowlands that were sea-beds when the moon had water
large volcanos
Explanation / Answer
33. They represent the large impact craters with basaltic lava.
34. Hydrogen and helium, but hydrogen gives more energy. So the answer is hydrogen.
35. Place it on land asa far as possible from the ocean. Because the oceanic winds will spoil the telescope.
36.Hydrogen is most abundant material on the atmosphere of both Jupiter and Saturn.
37. Red color has the longest wavelength of all the colors in visible light.
38. Pluto is not a jovian planets.
39.Gravity waves are not electromagnetic waves.
40. Comets have a highly elliptical orbits around the sun is true.
41. Neptune is known to have the highest winds in the whole solar system.
42. Venus rotates the opposite direction it revolves around the sun.
43.Xrays pass through materials because their photons are smaller than light photons.
