Answer: 20m
Explanation:
We will solve this question by applying the law of conservation of energy which states that the sum of potential energy and kinetic energy is always the same.
The PE is 0 at surface and maximum at top while the KE is maximum at surface and 0 at top.
From the question,
PE = mgh = 50 J -(1)
mg* 10 = 50
mg = 50/10
mg = 5
The total energy at that point = PE + KE = 50 + 50 = 100 J
Therefore, at topmost point, the PE will be 100 J
mgH = 100J , H is the needed height
Using the value of mg obtained above, we have
H= 100/5
H = 20 m
Answer:
Generally, a solute dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement. For example, if you add the same amount of sugar to a cup of hot tea and a cup of iced tea, the sugar will dissolve faster in the hot tea.
Answer:
The answer is Temperature.
