Q1. A 1.44 x 10^2 kg crate is being pushed across a horizontal floor by the force P that makes an angle of 30.0° below the horizontal. The coefficient of kinetic friction is 0.4. What should be the magnitude of P, so that the net work completed by it and the kinetic frictional force is zero?

Q2. The spring of the pressure gauge has a force constant of1000 n/m and the piston has a diameter of 2.00 cm as the gauge is lowered into water, what change in depth causes piston to move in by 0.50 cm?
