The total current through the circuit is 0. 19A
<h3>How to determine the current</h3>
We have the formula for power to be;
Current, I = V/R
Voltage = 7. 7V
Resistance in parallel = R1R2/ R1 + r2
Resistance in parallel = = = 41. 40 Ohms
Current = = 0. 19 A
Thus, the total current through the circuit is 0. 19A

<u>Answer:</u>
The correct answer option is: they are equal and opposite.
<u>Explanation:</u>
A force is a push or a pull which acts upon any object as a result of its interaction with another object where the forces are called action and reaction.
And according to the Newton's third law: for every action, there is an equal and opposite reaction.
For example, if a bat hits a ball with a 1000-N force, the force exerted on the bat will also be equal to 1000 N but in opposite direction.
The solution for the problem is:
Constant speed means Fnet = 0.
Let m = mass of wood block and Θ = angle of ramp; then if µk = 0.35 …
The computation would be:
Fnet = 0 = mg (sin Θ) - (µk) (mg) (cos Θ)
mg (sin Θ) = µk (mg) (cos Θ)
µk = tan Θ
Θ = arctan(µk)
= arctan (0.35)
≈ 19.3°
The magnitude of the action–reaction pair between the two boxes (A and B) will be "18.2 N".
According to the question,
Mass of box A,
Mass of box B,
Horizontal force,
From the Newton's law,
→
or,
→
Bu substituting the values, we get
→
→
→
We can see that between the two boxes, the action-reaction pair exist.
then,
→
→
→ (magnitude)
Thus the above solution is appropriate.
