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...

According to Newton's Second Law of motion, if the net force acting on the object increases while the mass of the object remains constant, what happens to the acceleration? Hint: Remember F = m * a - Acceleration Increases If the earth were moved to half its current distance from the sun, how would the force of gravity by the sun on the earth change? Hint: Recall the form of the equation that you derived, earlier in the game: "gravitational acceleration (g) is proportional to the mass (m...

Praxis PT 2 Middle School Science Questions and Answers Already Passed 10. In cold weather, it is more difficult to make people comfortable in a room with a high ceiling than in a room with a low ceiling primarily because Cold air is more dense than warm air is correct. Since cold air is more dense than warm air, convection currents will develop, with warmer air rising to the ceiling and cooler air dropping toward the floor. When the ceiling is high, there will be a greater temperature d...

NLN PAX Physics Exam (Answerd) Verified Solution Displacement Distance that an object is from some starting point, and it is measured in units of length. Motion when an object is in motion, it's displacement is constantly changing. -Velocity (speed) -Acceleration Speed Is the distance traveled by an object per unit of time. - Speed equals distance traveled over time. Velocity Speed in a given direction; it therefore tells us two things about a moving object, it's speed and direction...
