Oh okay the first person who answered is incorrect but
0—> PE=0J
1—>PE=1J
20—>PE=20J
50—>PE=50J
100—>PE=100J
The inductance of the coil and time is mathematically given as
<h3>What is the inductance of the coil and How long after S1 is opened will the current reach 1.00% of its original value?</h3>
Generally, the equation for Current is mathematically given as
Therefore
Hence, the Maximum current is,
Thus,
L=0.1035H
b)

The equation for gravitational force is provided. If you were to put 1/10 times d (distance) than 1/10 would be squared = 1/100. So the gravitational force would be 100 times more.
Answer:
(D) x = 93.8 m
Explanation:
v^2 = v0^2 + 2ax
(20 m/s)^2 = (5 m/s)^2 + 2(2 m/s^2)x
Solving for x,
x = 93.8 m
Answer:
150156.25 Ω
Explanation:
Resistance: This can be defined as the opposition to the flow of electric current in a circuit. The S.I unit of resistance is Ohm's (Ω)
The expression for resistance is given as
P = V²/R................ equation 1
Where P = power, V = Voltage, R = Resistance.
Making R the subject of the equation,
R = V²/P.................. Equation 2
Given: V = 115 V , P = 0.16 W.
Substitute into equation 2
R = 155²/0.16
R = 150156.25 Ω
Hence,
The resistance = 150156.25 Ω
