<span>Groundwater
Groundwater flows through rock with a high porosity and a high permeability at a fast rate. The denser and less permeable the rock is, the slower the groundwater moves. The greater the permeability of a rock, the faster the groundwater flows through it. Groundwater is water that is found in spaces and fractures in rocks, as well as in the sediment between the earth's surface. </span>
Answer: O White Anthurium
Explanation: I guess?!
Answer:
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
Explanation:
Electromagnetic waves include visible light, radio waves, X-rays, and so on. What distinguishes these different bands of light is their frequency (or wavelength). But what they all have in common is that they travel at the same speed in vacuum.
The reason for qualifying 'in vacuum' is because EM waves of different frequencies often propagate at different speeds through material.
The speed of a wave c, its wavelength λ and frequency f are all related according to c=λf. So if c is the same for all EM waves, then if you (say) double the frequency of a wave, its wavelength will halve.
Answer:
I'm not sure, but I think it's B
Explanation:
Condensation's is the conversion of a vapor or gas to a liquid, so I think it's B
