Aplayer bounces a basketball on the floor, compressing it to 80.0 % of its original volume. the air (assume it is essentially n2 gas) inside the ball is originally at a temperature of 20.0 ∘c and a pressure of 2.00 atm. the ball's diameter is 23.9 cm. by how much does the internal energy of the air change between the ball's original state and the maximum compression?

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.
