The chemical energy of the battery converts to electrical energy and then to radiant energy. Option C is correct.
<h3>
What is the law conservation of energy?</h3>
The energy neither be produced nor be destroyed it just change its form from one to another.
In the given question, the energy is stored in the battery as chemical energy, then it converts to electrical energy which runs through the wire and reaches the bulb where it converts to radiant energy.
Therefore, the chemical energy of the battery converts to electrical energy and then to radiant energy.

Answer:
y = 60 mph
Explanation:
given,
average speed of Sarah driving from Orlando to Tampa = 30 mph
average speed of return = ?
whole trip average speed = 40 mph
now,
Let x be the distance from Orlando to Tampa
y be the speed of return
60 + 2 y = 3 y
y = 60 mph
hence, speed of the return is equal to 60 mph.
Answer: 150 joules
Explanation:
Force applied on a block = 25N
Distance moved by block = 6 m
Workdone = ?
Recall that work is done when force is applied on an object over a distance. And it is measured in joules.
I.e Workdone = Force X Distance
= 25N x 6 metres
= 150 joules
Thus, 150 joules of work is done by the applied force.
The problem statement is simply asking us to convert units. We convert from units of ft^3 to units of m^3. To do this, we need a conversion factor. For this case, we use 1 m is equal to 3.28084 ft. We do as follows:
5.0 ft^3 ( 1 m / 3.28084 ft )^3 = 0.1416 m^3
