Answer:

TRUE - In any collision between two objects, the colliding objects exert equal and opposite force upon each other. This is simply Newton's law of action-reaction.

Answer:

The distance the mass would stretch it is $x = 0.00992948$

The correct option is A

Explanation:

From the question we are told that

The period of the slit is $T = 0.2s$

The acceleration due to gravity is $g =9.8 m/s^2$

Generally the period is mathematically represented as

$T = 2 \pi \sqrt{\frac{m}{k} }$

Whee m is the particle and k is the spring constant

making $\frac{m}{k}$ the subject

$\frac{m}{k} = [\frac{T}{2 \pi} ]^2$

The weight on the particle is related to the force stretching the spring by this mathematical relation

$W = F_s$

$mg = kx$

where x is the length by which the spring is stretched

$\frac{m}{k} = \frac{x}{g}$

Substituting the equation above for $\frac{m}{k}$

$[\frac{T}{2 \pi} ]^2 = \frac{x}{g}$

making x the subject

$x = g [\frac{T}{2 \pi} ]$

Substituting the value

$x = 9.8 * [\frac{0.2}{2 * 3.142} ]^2$

$x = 0.00992948$
