Answer:
Explanation:
Let assume that ball begins its movement at a height of zero. The height can be found by energy approach, to be precise, by Principle of Energy Conservation:
Answer:
1J
Explanation:
Work done = force × distance
1 × 1 = 1
Work done = 1J
J = Joules
The volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
<h3>Why does water change in volume?</h3>
Water is a substance that is known for its unique characteristics that makes it stand out among all other liquids.
One notable feature of water is it's ability to become denser when subjected to cooler temperatures i.e. water is more dense when cold.
As water cools or becomes less warm, it contracts and decreases in volume. When water decreases in volume, it becomes more dense.
Therefore, according to this question, it can be said that the volume of the water, which was initially 100mL changed to 96mL after refrigeration because the volume of water reduces when cool.
