The coefficient of kinetic friction between the 14-kg box and the inclined surface is mk = 0.1. The velocity of the box is zero when it is subjected to a constant horizontal force F = 20 N . What is the velocity of the box two seconds later?

Distinguish between a transverse wave and a longitudinal wave.

An ideal gas is held in a container at constant volume. initially, its temperature is 5 degrees c and its pressure is 1.2 atm. what is its pressure when its temperature is 43 degrees c? answer in units of atm

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
