If an object has a larger potential energy than kinetic energy a) the speed of the object will increase. b) the speed of the object will not change. c) the speed of the object will decrease. d) it is not possible to predict what the speed will be; it depends on the situation

A30 kg weight lies on top of a massless piston of area a = 0.01 m2 the exterior air is at a (constant) p =1 atm and t = 27 c. the interior gas is 0.4 moles of (ideal) n2 and it has initial temperature 27.00 degrees c. 1. what is the initial pressure in the interior? a. 29.4 kpa b. 130.7 kpa c. 101.3 kpa the next three questions concern what happens when an amount of heat q is slowly added to the interior, raising the piston by 1 mm and raising the interior temperature to 27.40 c

Blank liquids and gases exert a buoyant force on objects placed in them

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
