Answer:
C
Explanation:
because warm air is less dense, and warm air rises and cold air sinks. (did research) hope this helps!! :)
Answer:
physics answers everything to understand biology you need to understand chemistry which is connected to physics which is connected to mechanics like fluid mechanics or quantum mechanics which is connected to math and all of that is science not particularly physics but physics can answer all of the questions you asked and more.
Explanation:
This is what e=mc² means.
So rest energy is RH side of equation that is its mass times speed of light squared.
Answer:
n = 1,875
Explanation:
The speed of light in vacuum is constant (c) and in a material medium it is
v = d / t
The refractive index of a material is defined by
n = c / v
Let's look for the speed of light in the material, in general the length that light travels is known, this value is high, x = 1, when we place a block on the road, a small amount is lengthened by the length of the block, which in general is despised
These measurements are made on a digital oscilloscope that allows to stop the signals and measure their differences, that is, the zero is taken when the first ray arrives and the time for the second ray is measured,
v = d / t
v = 1 / 6.25 10⁻⁹
v = 1.6 10⁸ m / s
we calculate the refractive index
n = 3 10⁸ / 1.6 10⁸
n = 1,875
