Agirl on a backyard trampoline bounces straight upward with an initial velocity of 4.5 m/s. what is the girl's velocity when she returns to the trampoline

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

A1.5m wire carries a 2 a current when a potential difference of 52 v is applied. what is the resistance of the wire?

Gravity is pulling an object into the sun. the closer the object gets to the sun, the greater the gravitational force that acts on the object, increasing its acceleration. a line graph plotting the speed of the object against time would have which shape? a: straight line of positive slope b: curved line that slopes upward c: curved line that slopes downward d: straight line of negative slope
