Explanation:
Given: Initial Velocity=0
Final Velocity= 20 m/s
Time= 4 s
Accleration: Unknowns
Use kinematic equation
so a = 5 m/s^2

The current flowing in each resistor of the circuit is 4 A.
<h3>Equivalent resistance of the series resistors</h3>
The equivalent resistance of the series circuit is calculated as follows;
6 Ω and 4 Ω are in series = 10 Ω
5 Ω and 10Ω are in series = 15 Ω
<h3>Effective resistance of the circuit</h3>V = IR
I = V/R
I = 24/6
I = 4 A

Answer:
Explanation:
Take sum of torques at the point the step touches the wheel, that eliminates two torques
Σ
Since we are looking for when the wheel just starts to rise up N-> 0 so no torque due to normal force
The perpendicular lever arm for the F force is R-h
And the T of gravity according to the image
Σ
