PLEASE HELP! In the table below, data for a newly studied star, Excalibur, and some of the planets surrounding it are
displayed. The planets follow nearly circular paths around the central star. Examine the data and
diagram provided and determine which of the planets exerts the largest gravitational force on
Excalibur.
Write a scientific explanation that give mathematical evidence to support your claim and provides reasoning based on newton’s law of universal gravitation.

Heterogeneous mixture with larger particles that never settle is

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
