Theory of relativity shows that the speed of light doesn't depend
on the motion of the observer. All observers measure the same
speed of light no matter how they're moving.
It does NOT say that the speed of light is the same in any medium.
If the light is moving through a block of jello, then all observers in jello
will measure the same speed of light, no matter how they're moving
and whatever that speed is.
D: a force equal to the force
Answer:
<em>The mass of the block is 0.025 kg</em>
Explanation:
<u>Mass-Spring Harmonic Motion</u>
When a mass m is attached to a spring of constant k, they produce a simple harmonic motion which angular frequency is
We also know
which means
Squaring
Solving for m
We have
Operating
Simplifying and computing
The mass of the block is 0.025 kg
A neutral atom has the same number of protons as it does neutrons.
