After landing on an unfamiliar planet, a space explorer constructs a simple pendulum of length 49.0 cm. The explorer finds that the pendulum completes 99.0 full swing cycles in a time of 125 s. What is the value of the acceleration of gravity on this planet?

"12.122 m/s²" is the appropriate solution.

Explanation:

The given values in the question are:

Length,

l = 49.0 cm

or,

 =

Time taken,

Now,

As we know,

⇒  

or,

⇒  

By substituting the above given values, we get

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
