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.
