4 An airplane weights 21400 kg and is moving at 239 m/s while the engine pushes with 29530 N of force for 1250 m as the plane climbs 123 m. The plane experiences 15400 N
of friction force from air resistance as it moves. What speed will the place have when it
finishes the climb?

How does the space charge width change with forward and reverse bias? also, calculate the space charge width for a reverse bias of 4v on a silicon pn junction at t = 300k and doping concentrations of na = 5x1015cm-3 , nd = 5x 1016 cm-3 .

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
