I think the answers are box #1 and #3. It is number one for a fact. However, it depends where the start is at #3.
Energy stored= 1/2 * capacitance * voltage^2
= 1/2 * 10*10^-10* (1.7*1000)^2
= 1.7*1.7/2000 J
The average velocity can be calculated from the slope of the graph
Explanation:
In a position-time graph, the position is represented on the y-axis while the time is represented on the x-axis.
The slope of the graph is given by:
where
is the change in the y-variable
is the change in the x-variable
However, we have:
- corresponds to the change in position, therefore it is the displacement
- corresponds to the change in time
This means that the slope can be rewritten as
However, this ratio corresponds to the definition of average velocity:
Therefore, the slope of a position-time graph gives the average velocity.

This statement is false: More hitting among particles creates more energy which means a higher temperature, which in turn means higher pressure. Thus, this is a false statement.
Hope this helps!
Answer:
B.
Explanation:
The batteries make it so the chemical energy is being passed into the flashlight allowing it to work as designed forming light.
