D) Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.
While
Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero
Explanation:
Given that the lifts are analogous to batteries, and the runs are analogous to resistors.
So from all the figures. The resistors represent the runs while the lift represents the battery.
Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.
While
Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero

Try B, it seems correct. I’m very sorry if i’m incorrect.
W = F x d
Lifting a couch requires a force to displace the couch a certain distance
Throwing a baseball requires a force to be applied to the base ball for it to travel a certain distance
Running up stares requires work against gravity for you to reach the top of the stairs (displacement)
Carrying a box requires no force on the box, so therefore no work is done.
The windmills used mostly for pollution problems and farming and in a windmill there are 3 barrels that spin, but the barrels are tilted a little bit so when i spins it makes the wind go forward
