10 points.) a stone weighing 0.7 kilograms rolls down the inclined plane from position b to position a. position a is located at sea level. the inclined plane is 0.25 meters high.  the difference in the gravitational potential energy of the ball between positions a and b is joules. (use pe = m × g × h, where g = 9.8 n/kg.)

What is the momentum of a 2 kg object moving at 15 meters per second

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.

Write a hypothesis about the effect of increasing resistance on the current in the circuit. use theformat and be sure to answer the lesson question. “how do changes in voltage or resistance affect current in an electric circuit? ”
