Answer:
Value of the resistors R = 2 ohm
Explanation:
Given:
Resistor R1 = 4 ohm
Resistor R2 = 4 ohm
Find:
Value of the resistors R
Computation:
We know that Resistor R1 and Resistor R2 connected in parallel series.
So,
Using common resistance in parallel series
⇒ 1/R = 1/R1 + 1/R2
⇒ 1/R = 1/4 + 1/4
⇒ 1/R = (1 + 1) / 4
⇒ 1/R = 2/4
⇒ R = 4/2
⇒ R = 2
Value of the resistors R = 2 ohm
Answer:
0 m/s^2
Explanation:
Use a formula to answer the question
d = r * t
The object is not changing speed at any time, or if it is we are not told. The rate is the speed.
8 = r * 1 second
8 m/sec = r
The initial speed is 8 and the final rate is 8. There is no change. So when you use this formula
a = (vf - vi)/t we get a = (8 - 8)/1 = 0
There is no acceleration because there is no change in speed.
Acceleration is the rate of change in velocity
Answer:
38 m
Explanation:
Number of turns=N=100
Magnetic field=B=0.50 T
Frequency of the generator=f=60 Hz
Rms value of emf=
We have to find the length of the wire from which the coil is made.
Peak value of emf=
Length of wire=
Substitute the values
Length of wire=
Length of wire=38 m
Hence, the length of wire from which the coil is made=38 m
