Answer:
they slow down
Explanation:
Because number of electrons remain same in the closed circuit or wire, due to conservation of charge in any case. But due to addition of a external resistor current will decreases, by applying ohm's law( V=IR).
Answer:
<h3>Ion beams and Electrochemical are two examples of direct current electricity.</h3>
The moment of inertia is
Explanation:
The total moment of inertia of the system is the sum of the moment of inertia of the rod + the moment of inertia of the two balls.
The moment of inertia of the rod about its centre is given by
where
M = 24 kg is the mass of the rod
L = 0.96 m is the length of the rod
Substituting,
The moment of inertia of one ball is given by
where
m = 50 kg is the mass of the ball
is the distance of each ball from the axis of rotation
So we have
Therefore, the total moment of inertia of the system is
