#33. A planet of radius 7.0×10^7m has a gravitational field strength of 68N/kg at it's surface. What is the period of a satellite orbiting this planet at a radius of 1.4×10^8m (twice the planet's radius)? LIST THE GENERAL STEPS.
Step1. Find the correct equation and rearrange the equation to isolate for the period of the satellite.
Step2. Input values for the correct variables and calculate.

pg 67 # 37. A space station has an outer radius of 140m. The station rotates so that the occupants at X at the outer wall experience an acceleration of 9.8m/s². What acceleration will the occupants at Y experience at the 100m radius?
List all general steps to solve the problem.
Make a list of the given values to determine which formula to use.
rearrange ac=4π²r/T² for T in order to find the period of rotation for the whole station.
use T value as well as given values for100m radius to solve for ac at the Y area. ac=4π²r/T²

What is step 1 and 2?
Make a list of the given values to determine which formula to use.
rearrange ac=4π²r/T² for T in order to find the period of rotation for the whole station. You will need T in order to find the time for rotation of occupants at Y.

Which of the following graphs shows how the gravitational force varies with the distance of separation between two objects?
A graph typically shows an inverse square relationship, where gravitational force decreases as the distance increases.
A car moving in a circular path with a constant speed has __________ acceleration.
Centripetal Acceleration
Even though the car moves at a constant speed, its velocity is changing because velocity is a vector. Since the direction is continuously changing, there must be an acceleration.
This acceleration is called centripetal acceleration, and it is always directed toward the center of the circular path.
