Suppose you have two locations (stations A and B) that are 150km apart from each other. Station A is reporting a surface air pressure of 1023mb while Station B is reporting a surface air pressure of 1014mb. The pressure gradient between two cities would be:

A0.750 kg aluminum pan is removed from the stove and plunged into a sink filled with 10.0 kg of water at 293 k. the water temperature quickly rises to 297 k. what was the initial temperature of the aluminum pan? the specific heat of aluminum is ca = 900 j/(kgk) and water is cw = 4190 j/(kgk)

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
