In the engineering design process, what do engineers do immediately after brainstorming multiple solutions?

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Calculate the heat capacity per object when the total energy is 4 quanta. (think of this in terms of increasing from 3.5 quanta of energy in the system to 4.5 quanta of energy in the system, if that were possible.) c4 = __ j/k/object

Within a pendulum, as potential energy decreases, energy increases. a. heat b. kinetic c. frictional d. gravitational
