Answer:
Explanation:
Given
mass of block 
at 
displacement is 
velocity 
acceleration 
suppose
is the general equation of SHM
where A=amplitude
=natural frequency of oscillation
therefore velocity and acceleration is given by


for t=0



divide 1 and 3 we get


Now square and 1 and 2 we get



Answer:
magma
Explanation:
actually cooling and solidification of magma
F=ma
F = 148×(85-35)÷20
F = 148×(50÷20)
F = 148×2.5
F = 370N
Answer:
They were produced by stars that lived and died before our solar system was born.
Explanation:
According to what it's understood today, all elements heavier than hydrogen (including helium and excluding some that were created in laboratories) are created through nuclear fusion in the core of stars.
They start fusing hydrogen into helium, then as the star grows older helium is fused into beryllium and so on for all the periodic table.
So as far as science understands it today it's a literal truth that we are made of stars. (as almost everything else)
