If the gear rack is connected to the ground, and if p = 130 n, determine the angular velocity of the gear in 4 seconds, starting from rest. the gear has a mass of 30 kg and a radius of gyration ko = 125 mm.

Why is metal often used for cooking pan?

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final
