Using si units, calculate the change in potential energy of a 150-lb person riding the 15 ft long uphill portion of a water slide. the change in potential energy is defined as mgah where ? h is the change in vertical height. the uphill portion of the slide is set at an angle of 45°

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
