Answer (Part 1):
620 joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
<u>Formula</u>
Thus, Work = Force x distance
Since, Work = ? (unknown value)
<u>Given:</u>
Force = 200N
Distance = 1.2 meters
<u>So,</u>
Work = 200N x 3.1 meters
= 620 joules
Thus, Amanda did a work of 620 joules on the crate.
Answer (Part 2):
240.25 joules
Explanation:
Work is done when force is applied on an object over a distance. It is measured in joules.
<u>Formula</u>
Thus, Work = Force x distance
Since, Work = ? (unknown value)
<u>Given:</u>
Force = 77.5N
Distance = 3.1 meters
<u>So,</u>
Work = 77.5N x 3.1 meters
= 240.25 joules
Thus, Amanda did a work of 240.25 joules on the crate.
Hope this helps! :)
Answer:
A) initial stored energy = 5x10^-4 J
B) new voltage if space is doubled will be 2000V
C) if space is doubled, stored energy becomes 2x10^-3 J
D) the extra energy comes from the work done in moving the plates further apart
