The correct response would be C. Carpenter hammering a nail. The carpenter is applying a force as he or she is hitting the surface of the nail with the hammer.
The answer to this is that it is FALSE!
In summary, gravity is the force that creates the pressure to fuse atoms, which makes the stars shine. Eventually the temperature is high enough that the star starts fusing hydrogen into helium. When the outward pressure produced by the heating of the gas by fusion energy balances gravity, a stable star is formed.

Answer:
68.445 cm³/s
Explanation:
Given:
Volume, V = 
radius = 5.85 cm
Growth rate of radius = 0.5 cm/week
now
differentiating the volume with respect to time 't', we get:

or

now, substituting the value of r (i.e at r = 5.85cm) in the above equation, we get:

or

hence, the rate of change of volume at r = 5.85cm is 68.445 cm³/s
