If 19.00 mol of helium gas is at 19.0°C and a gauge pressure of 0.310 atm.
Calculate the volume of the helium gas under these conditions.
Calculate the temperature if the gas is compressed to precisely half the volume at a gauge pressure of 1.00 atm.
What is the mass of a boat if it travels at a velocity of 57.0 km/h [E] and has a momentum of 2.15*10^6 kg*m/s[E]?
Liz rushes down onto a subway platform to find her train already departing. She stops and watches the cars go by. Each car is 8.60 meter long. Evaluate the constant acceleration of the train
A 50.7-kg crate rests on a level floor at a shipping dock. The coefficients of static and kinetic friction are 0.628 and 0.358, respectively. What horizontal pushing force is needed to (a) just start the crate moving and (b) slide the crate across th..
Three air carts have masses, 4m,2m and m. the most massive cart hasan initial speed of Vo; the other two carts are at restinitially. All carts are equipped with spring bumpers that giveelastic collisions.
What is the angular acceleration of the door? How much force must you and your friend each apply to the free end of the door on the same side and perpendicular to the plane?
A 1-kg flower pot resting on a balcony 25 m above the ground. The railing gives way and it falls to the ground. If it is going 20 m/s when it hits the ground, how much heat did it create by friction on its way down?
A gymnast of mass 62.0 hangs from a vertical rope attached to the ceiling. You can ignore the weight of the rope and assume that the rope does not stretch.
