You would have done 240 joules of work on the box.
Work = (force) x (distance)
= (60 newtons) x (4 meters)
= 240 joules .
At any point, the electric field points in the direction of the force
on a positive point-charge located there. So the lines point away
from a positive charge, and toward a negative one.
Answer:
4 A
Explanation:
V = IR, where V=voltage, I=current, R=resistance. This is Ohm's Law. (remember that for units V = volts, Ω = ohms, A = amperes.)
V = IR
12 V = I * 3 Ω
12/3 = I
<u>I = 4 A</u>
1 particles have got forces of attraction between them
2 they vibrate and rotate at a fixed point
3 they gan heat energy in order for them to melt
4 particles are closely packed together
