Answer:
The <u>Fruit juice </u> should be put in the cooler, because <u>it has the greatest heat capacity</u> and will therefore, <u>absorb the most heat for each degree it increases in temperature.</u>
Explanation:
in order to understand the answer above we need to know what specific heat capacity is
Specific heat capacity can be defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree
Looking at the specific heat of each substance suggested we see that the fruit juice has a higher specific heat capacity than others this is because it contains a higher amount of water , generally liquid states of substances have a higher specific heat capacity than other states. The specific heat capacity of fruit juice being the highest among the suggested substances means that it can absorb more heat for each degree temperature of refrigerator.
The ball raised up the hill is given gravitational potential energy, which
causes it to roll spontaneously down the hill.
The statement that explains whether the ball rolling down the hill
experiment should be used is; <u>The experiment shows the ball falls toward </u>
<u>the bottom of the hill, so it provides direct evidence that gravity pulls an </u>
<u>object downward. They should use it.</u>
Reason:
The equation for the velocity of a ball falling down a hill is
Therefore, by increasing the height from which the ball rolls down the hill,
the velocity of the ball increases, which indicates that the ball is
accelerating, and therefore, being acted on by a force, the force of gravity.
Therefore;
Given that the ball falls or moves with increasing speed towards
the bottom of the hill, which shows that the motion is due to Earth's pull
known as the gravitational force, the experiment should be used.
