Pz 30 points answer only if you know
the correct expression for finding the period of a planet revolving around the sun is:

t = r^2(2π / gms)

t = r^3(4π^2 / gms)

t^2 = r^3(4π^2 / gms)

t^2 = r^3(2π / gms)

Acar is traveling at 53.0 mi/h on a horizontal highway. (a) if the coefficient of static friction between road and tires on a rainy day is 0.104, what is the minimum distance in which the car will stop?

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?
