Two equal masses are attached to separate identical springs next to one another. one mass is pulled so its spring stretches 20 cm and the other is pulled so its spring stretches only 10 cm. the masses are released simultaneously. which mass reaches the equilibrium point first?

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
