What is the period of a pendulum near Earth’s surface that is 130 cm long? Question 1 options:

2.3 s

0.83 s

9.1 s

22.9 s

A). 2.3 s

Explanation:

Given that,

Length of the string = 130cm or 1.3 m

g near Earth's surface = 9.8

To determine the period of a pendulum near Earth’s surface;

T = 2 π

T = 2π

T = 2.3 sec

Therefore, the period of the pendulum near the earth's surface is 2.3 sec.

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
