Ahydrogen atom has two electrons is it true or false

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

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?

A750 n force is applied to an object. if the object travles with a constant velocity of 18.2 m/s calculate the power exerted by object
