A. What can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>
<h3>
What is the principle of conservation of energy?</h3>
The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.
The energy of a system can be converted from one form to another.
Thus, what can happen to energy in a system is that <u>it can be </u><u>converted</u><u>.</u>

Answer:
second law
Explanation:
Newton's second law explains how much motion a force creates.
Answer:
10 million joules or 10,000 KJ
Explanation:
Work= Force x Displacement
convert 5km into meters -5km=5000m
W= 2000N x 5000m
w=10,000,000 Joules
or 10,000KJ
Answer:
B will take 1.034 times the time of A from Boston to Hartford.
Explanation:
Let the distance from Boston to Hartford be S.
Person A drives at a constant speed of 55 mph for the entire trip,
Time taken by person A
Person B drives at 65 mph for half the distance and then drives 45 mph for the second half of the distance.
Time taken by person B
Ratio of time of arrival of B to A
B will take 1.034 times the time of A from Boston to Hartford.
The circulation around the cylinder is 0.163Js/kg.
To find the answer, we have to know more about the stream flow.
<h3>
How to find the circulation around the cylinder?</h3>
, where d is the density at the sea level.
- We have the expression for lift per unit circulation as,
- Thus, the circulation around the cylinder is,
Thus, we can conclude that, the circulation around the cylinder is 0.163Js/kg.
