One mole of an ideal gas is heated so that T = AP2, where A is a constant and P is the pressure. The temperature changes from T0 to 4T0. Find out the work completed by the gas. (Use the following as necessary: T0, P0, and V0.)
find the minimum thickness for constructive interference of visible light with a wavelength of 595 nm.
How long would it take her to reach the bottom of the hill, assuming she starts from rest and accelerates uniformly, if the elevation change is 335m.
A 51kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 250N. For the first 10.5m the floor is frictionless, and for the next 10.5m the coefficient of friction is 0.18. What is the final speed of the crate af..
Computes the price per kwh for a 12-volt automobile battery with a 50 amp-hour capacity that sells for $40. If its weight is 45-lb, what is the energy density in watt-hours per lb.
An airplane's takeoff speed is 320 km/h. If its average acceleration is 2.90 m/s^2, how long is it on runway after starting its takeoff roll.
Find out the magnitude and direction of forces
A 4.00 kg block is free from rest 2.0m high at the top of a 30 degree frictionless incline. The block makes a head-on elastic collision with another 3.00 kg block initially at rest on a horizontal surface at the bottom of the incline.
You place one end of the pole on a fence post and hold the other end of the pole 35 from its tip. Explain how much force must you exert to keep the pole motionless in a horizontal position?
An 845-N sled is pulled a distance of 186m. The task requires 1.2 multiplied by 104 J of work and is done by pulling on a rope with a force of 133-N. At what angle is the rope held.
A child in a boat throws a 5.600 kg package out horizontally with a speed of 11.00 m/s. Determine the velocity of the boat immediately after, assuming it was initially at rest. The mass of the child is 23.00 kg and that of the boat is 45.00 kg.
What is magnitude of the unknown force
