A 3.5 kg wooden block is pulled with 12.5 N of force across a rough surface. If the force of friction is 4.8 N, find the net force and the acceleration of the block. (Start by drawing a force diagram.)

An air-standard stirling cycle operates with a maximum pressure of 600 psia and a minimum pressure of 10 psia. the maximum volume of the air is 10 times the minimum volume. the temperature during the heat rejection process is 100°f. calculate the specific heat added to and rejected by this cycle, as well as the net specific work produced by the cycle. use constant specific heats at room temperature. the properties of air at room temperature are r

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Explain how the energy of rubber ball is tranforned as it roll down a ramp. give evidence that the energy of the og the ball remains the same at all points on the ramp
