Answer: True!
Explanation: The force is proportional to the square of the distance between 2 point masses
The temperature of a balloon is
lowered with liquid nitrogen. The balloon appears to deflate because the gas in
the balloon lost energy and condensed. The answer is letter D.
Answer:
0.31 m
Explanation:
m = mass of the block = 1.5 kg
H = height from which the block is released on ramp = 0.81 m
k = spring constant of the spring = 250 N/m
x = maximum compression of the spring
using conservation of energy
Spring potential energy gained by spring = Potential energy lost by block
(0.5) k x² = mgH
(0.5) (250) x² = (1.5) (9.8) (0.81)
x = 0.31 m
Soory i think multiple of velocity and angle
