What is the specific heat of the masses in this experiment? Infer the substance the masses are made of and explain your inference using your data as support. Show your work.

If the force of friction is acting on the sliding crate is 100 N how much force will be applied to maintain a constant velocity? what will the net force be acting on the crate? what will be the acceleration?

The Roky mountain system is stretching from Canada to Mexico is a string of mountains running along the western United States. Wha factor would most likely cause the arrangement of mountains

A 600 kg car is at rest, and then accelerates to 5 m/s. What is its original kinetic energy? J What is its final kinetic energy? J How much work was used? J

Two friends are having a conversation. Anna says a satellite in orbit is in freefall because the satellite keeps falling toward Earth. Tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2.

Describe the method by which an electrical potential developed in generators and thermocouple?

Under what condition (s) will an object be in equilibrium? Notice that equilibrium in physics has a broader definition. (A) Only if it is moving with constant velocity. (B) Only if it is at rest.

If a pressure gauge measure an increase in 3*10^ (5) Pa on an area of 0.7 m^2, calculate the increase in the force applied to the area?
