Answer:
a) The electric potential between the cylinders,
b) The electric field between the cylinders,
Explanation:
Voltage at the inner conductor, V₁ = 20 volts
Voltage at the outer conductor, V₂ = 100 volts
Change in potential,
The change in potential is given by the formula:
The electric field,
To get the electric potential at a certain point, L from the center:
The distance from the outer conductor to the center = b - L
The electric potential at L will be given by the equation:
Answer:
I think the answer probably be B
At the moment contact is made with the battery, the voltage across the inductor is zero
At the instant the switch is closed, there is no current in the resistor (the inductor has prevented that), and therefore, there is no voltage across the resistor
<h3>What is Voltage ?</h3>
When charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they can perform tasks like lighting a lamp. In a nutshell, voltage equals pressure and is expressed in volts (V).
- DC voltage and AC voltage are the two different types of voltage. In a battery, for example, the DC voltage (direct current voltage) is always of the same polarity (positive or negative). Positive and negative waves interchange within the AC voltage (alternating current voltage).

Answer:
ω= 2.095rad/sec
Explanation:
angular frequency(ω)=2πf
F is the frequency
Frequency of an oscillation is the number of cycles completed per second. One oscillation represents 1cycle. Thus for 13 oscillations, the glider completes 13 cycles.
F= 13/39 =Hz
angular frequency(ω)=2πf
angular frequency(ω)=2π *
= 2**rad/sec
ω= 2.095rad/sec
