Answer:
Explanation:
Current, I = 6 A
diameter of wire, d = 2.05 mm
number of electrons per unit volume, n = 8.5 x 10^28
If the diameter is doubled,
The resistance of the wire is inversely proportional to the square of the diameter of the wire, so the resistance is one forth an the current is directly proportional to the diameter of the wire so the current is four times the initial value.
If its not Distance traveled then its energy
That's the 'electrostatic' force.
Answer:
a
The speed is
b
The distance is 
Explanation:
From the question we are told that
The speed of the banana is 
The distance from my location is
The time taken is 
The speed of the ice cream is

substituting values


The distance of separation between i and Valdimir is the same as the distance covered by the banana
So
substituting values

Answer:
5.43 x 10^-3 Nm
Explanation:
N = 52.5, radius, r = 5.35 cm = 0.0535 m, B = 0.455 T, I = 25.3 mA = 0.0253 A
Torque = N I A B Sin theta
Here, theta = 90 degree
Torque = 52.5 x 0.0253 x 3.14 x 0.0535 x 0.0535 x 0.455
Torque = 5.43 x 10^-3 Nm
