Answer:1688.393 joules

Explanation:

force along 15°(f) =380N

Φ=15°

Distance=4.6m

Time=9.5s

work=horizontal component force(F) x distance

Horizontal component force=f x cosΦ

Horizontal component of force=380 x cos15

Horizontal component of force =380x0.9659

Horizontal component of force=367.042N

Work=force horizontal component x distance

Work=367.042 x 4.6

Work=1688.393

Work=1688.393 joules

What is the difference between a circuit and a current?
dimulka [17.4K]

Answer:

a circuit is a complete loop that carries a current in the form of electrons from negative to positive

Explanation:

The difference between current and circuit is that a circuit is a complete loop that carries a current in the form of electrons from negative to positive .

In a circuit, there are difference elements or components such as the battery, wire, resistor. The goal of a circuit arrangement is to completely carry current from one end to another.

The current is the quantity of charge that flows within the circuit per unit of time.

So, the battery supplies the electromotive force to move the current round the circuit.
