Answer:

Explanation:
Given that,
The refractive index of benzene is 2.419
We need to find the speed of light in benzene. The ratio of speed of light in vacuum to the speed of light in the medium equals the refractive index. So,

So, the speed of light in bezene is
.
Energy is passed from organisms at one trophic level to organisms in the next trophic level. ... Energy is an open system: flows from the sun to the earth and then out for the earth as heat. What is a trophic level? The feeding positions in a food chain or web are called trophic levels
Your answer is 3 or C
When plates approach one another, the dense plates slips underneath the less dense one
I had this question before can you show me the answer choices
Power<span> is the rate of doing work. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. We express it as follows:
P = W / t
where W = Fd
F = mg
Therefore,
P = mgd / t
P = (30)(9.81)(20) / 1 = 5886 W</span>
