A molecule, would be the correct answer
Answer:
Option C
Explanation:
Revolution: When an object moves around another object it is called revolution.
Rotation: When an object spins around its axis it's called rotation
At one later moment, its speed is 1. 20Mm/s (non relativistic because v is much less than the speed of light).
Answer:
-414.96 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration


The force the ground exerts on the parachutist is -414.96 N
If the distance is shorter than 0.75 m then the acceleration will increase causing the force to increase
X=.5a(t^2), x=70m, t=3.6s, a=?. a=140/(3.6^2)=10.8m/s^2.
