Question

Question 2 of 5 The image at the right shows a pendulum. The length of the Map pendulum is 1.50 m, and the mass of the bob is 2.50 kg Answer the three questions below using three significant figures Part A: If the length of the pendulum is increased to 6.00 m, what happens to the period of the pendulum? O It is quadoupled. It is doubled It is unchanged It is half as much It is one-fourth as much 0 O Part B: If the mass of the pendulum is increased to 10.0 kg, what happens to the period of the pendulum? It is quadroupled It is doubled It is unchanged It is half as much It is one-fourth as much O 0 Part C: This pendulum is taken to planet Xeno, and it is found to have a period of 2.90 s. What is the acceleration of gravity on Xeno? Number

Explanation / Answer

here ,

the time period of pendulum is given as

T = 2pi * sqrt(L/g)

part A) when length is increased to 6 m

L2 = 6 m

L1 = 1.5 m

>> L2 = 4 * L1

the time period will be DOubled.

part B)

Period of pendulum is independent of mass of pendulum

the correct option is

It is unchanged

part C)

time period is T

T = 2.90 s

2.90 = 2pi * srqt(L/g)

2.90 = 2pi * sqrt(1.5/g)

solving for g

g = 7.04 m/s^2

the acceleration due to gravity is 7.04 m/s^2
