Answer:
The spring constant of the spring is 180 N/m.
Explanation:
It is given that,
Mass of the block, m = 0.42 kg
The block is pulled so that the spring stretches for 2.1 cm relative to its unstained length.
When the block is released, it moves with an acceleration of . We need to find the spring constant of the spring. For a block to be in equilibrium, the net force is given by :
k is spring constant of the spring
So, the spring constant of the spring is 180 N/m.
The inter molecular force of attraction between molecules decreases with increase in temperature. Because due to increase in temperature, the kinetic energy of the molecules increase and they starts moving with higher velocity.
