Part B Tape a meter stick to the side of the table. Make sure the zero end is on the floor. Carry out the experiment using the four
drop heights you chose in task 1, part D. (You may want to have an adult drop the ball while you watch how high it
bounces.) Perform three trials for each drop height, and record the data in the table. (You may choose
video the
bounces and watch the video in slow motion to improve your data collection.) Finally, average e the bounce height
measurements to get a final reading. Round the average bounce heights to the nearest whole number.

a.) is the correct answer.

explanation:

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
