Newton's Third Law Louisa builds the body of a race car out of cardboard. She tapes a straw to the cardboard so that one end of the straw is tilted up
and the other end hangs over the back of the car. Then, she places an inflated balloon over the tilted end of the straw and releases
the mouth of the balloon to allow air to flow through the straw. The race car rolls forward as the balloon releases air through the
straw, as shown in the picture below

How does Louisa's race car demonstrate Newton's third law of motion?
А
The forward movement of the car forces air to leave the balloon faster
B.
The forward movement of the car forces air to leave the balloon slower.
C.
The balloon pushes the air out, and the air pushes back on the balloon
D
The balloon pushes against the air, which results in a zero net force on the balloon

Asystem containing an ideal gas at a constant pressure of 1.22×10^5 pa gains 2140 j of heat. during the process, the internal energy of the system increases by 2320 j. what is the change in volume of the gas?

Aball is thrown upward. at a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the potential energy equal to zero at ground level) and is moving upward with a kinetic energy of 50 joules. what is the maximum height h reached by the ball? consider air friction to be negligible. 1. h ≈ 10 m 2. h ≈ 50 m 3. h ≈ 30 m 4. h ≈ 40 m 5. h ≈ 20 m 003 10.0 points which of the two object shown below has the greatest kinetic energy? a m b 1 2 m v 2v 1. kinetic energies are the same. 2. a 3. b 4. unable to determine. 004 10.0 points tim, with mass 74.6 kg, climbs a gymnasium rope a distance of 3.1 m. the acceleration of gravity is 9.8 m/s 2 . how much potential energy does tim gain? answer in units of j. 005 10.0 points a car is moving at 64 miles per hour. the kinetic energy of that car is 5 × 105 j. how much energy does the same car have when it moves at 111 miles per hour? answer in units of j. 006 10.0 points an 102 kg man climbs up a 1 m high flight of stairs. the acceleration of gravity is 9.81 m/s 2 . w
