The total resistance and current flowing through the circuit is equal to 60 Ohms and 2 Amperes respectively.
<u>Given the following data:</u>
Resistors = 20 Ohms.
Voltage = 120 Volts.
<h3>How to determine the total resistance.</h3>
Since the three resistors are connected in series, we would calculate their total resistance by adding them up as follows:
RT = R1 + R2 + R3
RT = 20 + 20 + 20
RT = 60 Ohms.
Next, we would determine the current that is flowing through the circuit by applying Ohm's law.
From Ohm's law, we have:
V = IR
I = V/R
I = 120/60
I = 2 Amperes.

In a force diagram set-up, we name the angle of inclination theta, g as the acceleration due to gravity. In this case, the forces acting on the box going down is the weight itself impeded by the friction between the box and the inclined plane.
The weight of the box is expressed as mg sin theta
The frictional force is expressed as the normal force times the coefficient of friction that is expressed as mu g cos theta.
By Newton's second law of motion, F = ma = mg sin theta - mu g cos theta
Thus, a = g (sin theta - u cos theta
Total energy before the toss:
Total energy at the roof:
Energy must be conserved so :
If v₁ is the initial velocity and v₂ is the final velocity, which is zero at the roof:
Answer:
A) 200 j
B) 0 J
C) -100 J
D) -300 J
Explanation:
We know that change in potential energy is given as
where, mg is weight
yf and yi final and initial position
mg = 10 N
yf = 0 m
yi = 20 m
B) mg = 10 N
yf = 20 m
yi = 20 m
c) before fall from the drone
U = mgh
h = yf - yi = 20 - 30 = -10 m
D) point has 0 potential energy
mg = 10 N
h = yf -yi = 0 -30 = - 30 m
