Answer:
Explanation:
Expression for relative velocity
= 
= (.54 + .82 )c/ 
= 1.36 c / 1.4428
= .94 c
β = .94
When minerals are exposed to high pressure and temperatures, the individual minerals begin to realign themselves
Answer:
It will take 30 seconds to reach the ground, and it will be travelling at 294 m/s when it does so. This means that its average velocity was 147 m/s.
Explanation:

Since the initial velocity of a dropped object is 0, we can make this the equation:


The final velocity can be calculated with the formula:

Once again, since there is no initial velocity:

Since the initial velocity is 0, the average vertical velocity is 294/2=147 m/s.
Hope this helps!
