A skydiver prepares to jump out of a plane. Explain how gravity and air resistance will affect the motion of the sky diver before and after he or she opens the parachute.

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

=force × distance a. work b. velocity c. pressure d. momentum

Ascientific blank must be testable and capable of being proven false?
