A gas initially at STP is heated to 50°C keeping the volume constant. What is its new pressure? I used this formula: P1 = 1 atm T1 = 273 K T2 = 323 K solve for P2 P2 = P1 (T2/T1) But, where do I use the 50 degrees C? Also, is my answer correct: P2 = 1atm x 323K/273K = 1.18...

For the case of freefall, explain how to calculate the total distance traveled and the instantaneous velocity for an object that is dropped from rest by applying the fundamental meaning of acceleration and by using the two equations: Vav+(vf+vi)/2 and d=vav+t. Is this method ...

A 2.4-kg cart is rolling along a frictionless, horizontal track towards a 1.3-kg cart that is held initially at rest. The carts are loaded with strong magnets that cause them to attract one another. Thus, the speed of each cart increases. At a certain instant before the carts ...

An object starts sliding up a plane tilted at an angle of alpha = 5.0◦ to the horizontal. The objects initial speed is v = 2.0m/s. How far from the start point does the object come to a stop if μK = 0.20?

Explain how acceleration can be slowing down. Calculate the impact force of a 50 kg object travelling at 100km/hr. (Momentum = mass x velocity) Calculate the momentum of a tennis ball of 50 g moving at a velocity of 25m/s.
