g A spring with a spring constant of 1830 N/m is compressed 0.126 m from its equilibrium position with an object having a mass of 1.67 kg. The spring is released and the object moves along a frictionless surface when it reachs a small embankment. If the speed of the object is 2.39 m/s at location A, what is the embankment's height h

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?
