(a) suppose that your measured weight at the equator is one-half your measured weight at the pole on a planet whose mass and diameter are equal to those of earth. what is the rotational period of the planet?

7160.2812 s or 1.988 hours

Explanation:

m = Mass of person

R = Radius of Earth =

g = Acceleration due to gravity = 9.81 m/s²

= Angular speed

Force at equator would be

Force at pole

From the question

Time period is given by

The rotational period of the planet is 7160.2812 s or 1.988 hours

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
