1 point You can calculate gravitational potential energy by using the equation
GPE (J) = 1/2m (kg) x 1/2h (m)
O GPE (J) = m (kg) x 9.8 m/s2 xh (m)
Ο Ο Ο Ο
GPE (J) = h (m) x 9.8 m/s2
GPE (J) = 1/2h (m) x W (m)

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

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity
