Acertain simple pendulum has a period on the earth of 2.00 s .
1. what is its period on the surface of mars, where the acceleration due to gravity is 3.71 m/s^2?

5.3 s

Explanation:

= Time period of simple pendulum on earth = 2.00 s

= Time period of simple pendulum on mars

= acceleration due to gravity on earth = 9.8 ms⁻²

= acceleration due to gravity on mars = 3.71 ms⁻²

= length of the pendulum

we know that, time period of pendulum is given as

So

Time period of pendulum is inversely related to acceleration due to gravity

hence

a straight line sloped

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
