<span>According
to the special theory of relativity, all laws of nature
are the same in
reference frames that move at constant speeds.
That means that there's no test or measurement you can do to
detect whether you're moving at a constant speed</span> or how fast.
And THAT means that there's no such thing as "who's REALLY
moving" and "who's REALLY at rest". There's no such thing as
"real" motion, only motion relative to something else.
Answer:
v = 0
Explanation:
This problem can be solved by taking into account:
- The equation for the calculation of the period in a spring-masss system
( 1 )
- The equation for the velocity of a simple harmonic motion
( 2 )
where m is the mass of the block, k is the spring constant, A is the amplitude (in this case A = 14 cm) and v is the velocity of the block
Hence
and by reeplacing it in ( 2 ):
In this case for 0.9 s the velocity is zero, that is, the block is in a position with the max displacement from the equilibrium.

I have asked question in my profile please tell me the answer
<span>Commonly when we talk about gases in science, we describe them as having the characteristics of a liquid. Imagine a rock in a bucket with liquid surrounding it. The liquid surrounds the rock and exerts pressure on it from all sides. Atmospheric pressure is much the same way. It surrounds the object and exerts pressure on it from all sides as well. Weight describes the force that gravity exerts on a mass whereas atmospheric pressure depends on the density of air at a certain point. If there were less air in our atmosphere (like Mars) the pressure would be much less and the opposite is true as well. However, the mass of a solid object would not change due to this change in air pressure and would weight the same regardless of the atmosphere.</span>
