AP Physics Final Exam Quiz Bank | Questions and Verified Answers | Grade A (2023/ 2024 New Update) Q: A 50. kg girl on ice skates, initially at rest, pushes against a wall, extending her arms 0.25m for 0.10s causing her to accelerate. Find the magnitude of the force applied by the girl to the wall. Answer: 2500 N Fg=ma x= (1/2) a t2 + v0t a = 2 x / t2 a = 2*0.25 / 0.12= 50 m/s2 Fg=ma = 50 kg * 50 m/s2 = 2500N Third Law Fg=Fw=2500N Q: Assume an astronaut, including his spac...

State the first law of thermodynamics - Answer The first law of thermodynamics states that the heat added to a system transforms to an equal amount of some other form of energy (energy conservation). Energy can neither be created nor destroyed. How does the law of conservation of energy relate to the first law of thermodynamics? - Answer Energy can neither be created nor destroyed. State the second law of thermodynamics. - Answer The second law of thermodynamics states that heat never spon...
