Abody of a mass 1kg suspended from a spring is found to stretch the spring by 10cm. (a) what is the spring constant? what is period of oscillation of the body if the motion is shm

(A) The spring constant is 98 N/m.

(B) The period of oscillation is 0.635 s.

Explanation:

Given:

Mass of the body is,

Extension length of the spring is,

Now, let 'k' be the spring constant.

The force acting on the body is due to gravity only and is equal to its weight.

So, weight of the body is given as:

Now, we know that for a spring-mass system, the net force acting on the body is equal to the product of the spring constant and extension length. Therefore,

Hence, the spring constant is 98 N/m.

(B)

Period of oscillation of a body of spring-mass system in SHM is given as:

Plug in the given values and solve for period 'T'. This gives,

Therefore, the period of oscillation is 0.635 s.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
