Generally the total force acting on the car is the net force plus the force due to gravity acting in direction of the car (Let denote it as $F__{dg}$ )

So the total force acting on the car is mathematically represented as

$F_{net} + F__{dg}} = F$

Here this F representing the total force can be mathematically represented as

$F = ma$

Now for constant velocity to be attained, the acceleration of the car will be zero

So at constant velocity

$F = m * 0$

=> $F = 0 \ N$

$F_{net} + F__{dg}} = 0$

=> $F__{dg} }= -F_{net}$

=> $F__{dg} }= -3674 \ N$

Which parts of an electric generator are connected?

Anna71 [15]

Answer:

the armature and commutator

Explanation:

An electric generator converts mechanical energy to electrical energy. It is based on the principle that when a conducting coil rotates in the magnetic field, an electric current is generated.

The rotating part is known as Armature. Commutator is cylindrical in shape and connected to armature which rotates with it. It also connects the armature to the external circuit by brushes.

Slip rings are connected to armature coil to maintain an electrical contact with the brushes.
