Question

Do the data for the second part of the experiment support or refute the second hypothesis? Be sure to explain your answer

Answer 1

The data for the second part of the experiment support the second hypothesis. As the mass of the cart increased, the acceleration of the cart decreased. Since the increase in the cart's mass caused the decrease in the cart's acceleration, mass and acceleration are inversely proportional to each other, which is in accordance with Newton's second law.

Step-by-step explanation:

Answer 2

Answer: The data for the second part of the experiment support the second hypothesis. As the mass of the cylinder increased, the temperature of the water increased. With a greater mass, the cylinder has more gravitational potential energy. This gravitational potential energy was completely converted to thermal energy, which increased the temperature of the water.
