of a string.A grandfather clock is "losing" time because its pendulum moves too slowly. Assume that the pendulum is a massive bob at the end of a string.The motion of this pendulum can be sped up by:- shortening the string.- lengthening the string.- increasing the mass of the bob.- decreasing the mass of the bob.

Answer:

shortening the string

Explanation:

L = Length of pendulum

g = Acceleration due to gravity = 9.81 m/s²

Time period of a pendulum is given by

T=2\pi \sqrt{\dfrac{L}{g}}

T\propto \sqrt{L}

It can be seen that time period is proportional to the length of the pendulum.

The time period is getting longer.

So, if the length of the string is reduced this will speed up the time period.

Pavlova-9 [17]

Answer:

If child weight is equal to rope force then child will move with uniform speed

or we can say that the child will remain at rest in his position

Explanation:

As we know that child is hanging by rope

so here there will be two forces on the child

1) Weight or gravitational force which act vertically downwards

2) Tension in the rope which act vertically upwards

Now if child will accelerate upwards then tension force must be more than the weight of the child

If tension force is less than the weight then child will decelerate and his speed will decrease

if tension force is equal to child weight then in that case the child will remain at rest or it will move with same speed
