Q: The tails of the hale-bopp comet point away from the sun, evidence that light has what property of motion? Read this paragraph and choose the correct option from the provided answers: Figure 29.17 The tails of the Hale-Bopp comet point away from the Sun, evidence that light has momentum. Dust emanating from the body of the comet forms this tail. Particles of dust are pushed away from the Sun by light reflecting from them. The blue ionized gas tail is also produced by photons interacting with atoms in the comet material. (credit: Geoff Chester, U. Navy, via Wikimedia Commons). Choices: - inertia - velocity - acceleration - momentum A:
**Answer**
momentum

Q: What type of energy causes erosion at the shore? Read this paragraph and choose the correct option from the provided answers: Wave energy does the work of erosion at the shore. Waves erode sediments from cliffs and shorelines. The sediment in ocean water acts like sandpaper. Over time, they erode the shore. The bigger the waves are and the more sediment they carry, the more erosion they cause ( Figure below ). Choices: - tidal - potential - kinetic - wave A:
**Answer**
wave
