Answer: The particles of a solid are [generally] closest together while those of a gas are farthest apart
Explanation:
Ohm’s law states:
I*R = U
So we just fill in:
U = 11 A * 60 Ω = 660 V
The maximum magnitude of the net force on the box is 20 N, which is only possible if the boy and the girl pull the box together in the same direction, horizontally and parallel to the ground.
The minimum magnitude of the net force on the box is 0 N, which will occur when the boy and the girl pull the box together in the parallel but opposite direction.
If either of them pulls at an angle from the horizontal, then the magnitude of the net force will be between 0 N and 20 N.
T=distance over speed
