7 0

Answer:

please give me brainlist and follow

Explanation:

Yes if the body is travelling with uniform speed in a circular track its speed remains the same but the velocity is non-uniform as the direction of the body is changing every time.

Most grandfather clocks have pendulums with adjustable lengths. One such clock gains 10 min per day when the length of its pendu
7nadin3 [17]

The length to which the pendulum will be adjusted to keep perfect time is 29.59 inches. See the explanation below.

<h3>What is the justification for the above answer?</h3>

T1 = 2πR√(L1/GM)

and

T2 = 2πR√(L1/GM)

T1/T2 = √(L1/L2).

If the pendulum has an efficient period, that means it executes with perfect frequency.

Thus,

T2 = (24 * 60)/x

= 1440/x

This means that in one day, there are perfect cycles of represented by "x". Note that there are 1440 minutes in one day.

If the other Pendulum is slower by 10 minutes, that means

T1 = 1450/x

Hence

(1450/x)/(1440/x) = √(L1/L2).

⇒ 1450/1440 = √(L1/L2).

Thus,

(1450/1440)² = 30/L

L = 30/(1450/1440)²

L = 30/(1.00694444444)²

L = 30/1.01393711419

L = 29.5876337695

L $\approx$ 29.59 inches.

Hence, the pendulum will need to be adjusted by 29.59 inches to ensure that the clock keeps perfect time.
