Answer:
55.68 μT
0.12 mH
Magnetic flux and magnetic field
Explanation:
i = Current = 40 mA
N = Number of turns = 435
D = Diameter of solenoid = 16.5 mm
l = Length of wire = 12.5 cm
A = Area of solenoid =
= Vacuum permeability =
Magnetic field of a solenoid is given by
The magnetic field inside the solenoid is 55.68 μT
Magnetic flux is given by
The magnetic flux through each turn is
Inductance of solenoid is given by
The inductance of the solenoid is 0.12 mH
As can be seen from the formulae above magnetic flux and magnetic field depend on current.
Answer:
Answer:
A. Increasing the number of lines per length.
Answer:
1 second later the vehicle's velocity will be:
5 seconds later the vehicle's velocity will be:
Explanation:
Recall the formula for the velocity of an object under constant accelerated motion (with acceleration ""):
Therefore, in this case and
so we can estimate the velocity of the vehicle at different times just by replacing the requested "t" in the expression:
Yes they are all correct

Answer:
1160 ohm
Explanation:
We are given that
R'=580 ohm
Current=3 I
We have to find the resistance of the circuit.
Let R be the resistance of circuit.
In parallel
Using the formula
In parallel combination,Potential difference across each resistance remains same.
Using the formula
