You build a grandfather clock, whose timing is based on a pendulum. You measure its period to be 2s on Earth. You then travel with the clock to the distant planet CornTeen and measure the period of the clock to be 4s. By what factor is the gravitational acceleration constant g different on planet CornTeen compared to g on Earth

Explanation:

The period of the simple pendulum is:

Where:

- Cord length, in m.

- Gravity constant, in .

Given that the same pendulum is test on each planet, the following relation is formed:

The ratio of the gravitational constant on planet CornTeen to the gravitational constant on planet Earth is:

atomic = no of protons.

mass number-atomic number = neutron number

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
