In a gas-powered car, a battery produces electrical energy to start the motor. (C)
Answer:
Yes, the magnet force will cause the motor rotate through a full rotation. So the friend who claims to have built a motor by attaching a shaft to the core of a galvanometer and removing the spring is correct.
Answer:
<h2>
137.69°</h2>
Explanation:
The phase angle of an RLC circuit ϕ is expressed as shoen below;
ϕ =
Xc is the capacitive reactance = 1/2πfC
Xl is the inductive reactance = 2πfL
R is the resistance = 25.0Ω
Given C = 35.5 μF, L = 0.0940 H, and frequency f = 70.0Hz
Xl = 2π * 70*0.0940
Xl = 41.32Ω
For the capacitive reactance;
Xc = 1/2π * 70*35.5*10⁻⁶
Xc = 1/0.0156058
Xc = 64.08Ω
Phase angle ϕ =
ϕ =
Since tan is negative in the 2nd quadrant;
Hence the phase angle ϕ of the circuit in degrees is 137.69°
Answer:
