Aball of mass 5.0kg is lifted off the floor a distance of 1.7m. 1. what is the change in the gravitational potential energy of the ball? 2. now you release the ball from rest, and it falls to the floor. what is the kinetic energy of the ball just before it hits the floor? 3. what is the velocity of ball just before it hits the floor?

10 points! will mark brainiest! in a heat engine if 1,000 j of heat enters the system and the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2,000 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 energy added you so much!

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
