My problem is understanding this because I have to calculate the mass and radius of 3 planets along with the graviational acceleration and then find the period of a 2 meter long pendulum on each planet for the assignment.

The instructor posted a formula that he used in Excel but there was no explanation.

The formula: =6.67x(10^-11) x 3x(10^25)/(64x(10^12))

Ok the basic formula for the Force attributed to gravity is:

F = {GM/r^2 } m = mg

The constant G appearing in Newton's law of gravitation, also known as the universal gravitational constant,
G is supposed to be a universal constant ...

Solution Summary

Information is provided as to how to calculate Radius, Mass of Planets and Period of a Pendulum.

Find the massand the radii of the planets Mercury, Neptune and Pluto, masses in kilograms and radii in meters. With that data calculate the gravitational acceleration on each of the planets in kilograms and meters and show the gravitational acceleration in meters per square second. With the gravitational acceleration from abo

Using the internet, I need to find the massand radius of three of the nine planets in our solar system. Be sure that the masses are expressed in kilograms and the radii are expressed in meters.
Using the data, calculate the gravitational acceleration on each of the three planets you selected. Note: With the masses measured

PLEASE SHOW WORK, POST FORMULA, CALCULATIONS AND ANSWER-
Search the Internet to find the massand radius of Mars, Venus and Jupiter in our solar system.
THE MASSES MUST BE EXPRESSES IN KILOGRAMS AND RADII EXPRESSED IN METERS
1. Using your data, calculate the gravitational acceleration on each of the three planets

I need the massand radius of three of the nine planets in our solar system. Be sure that the masses are expressed in kilograms and the radii are expressed in meters. I chose Pluto, Venus, and Mars.
Using your data, calculate the gravitational acceleration on each of the three planets you selected. The masses should be measure

Background Information:
A simple pendulum, such as a rock hanging from a piece of string or the inside of a grandfather clock, consists of a mass (the rock) and a support (the piece of string).
When the mass is moved a small distance away from its equilibrium point (the bottom of the arc), the mass will swing back and forth

A simple pendulum, such as a rock hanging from a piece of string or the inside of a grandfather clock, consists of a mass (the rock) and a support (the piece of string).
When the mass is moved a small distance away from its equilibrium point (the bottom of the arc), the mass will swing back and forth in a constant amount of t

Determine the orbital radius for the extrasolar planets x and y. Answers should be in astronomical units.
The planets are orbiting two stars with the same mass as our sun (1.9891 x 10^30kg). The planets are in two separate solar systems.
There are no other planets in either system and both stars are at a distance of 1000p
