Answer:
Option B
Explanation:
The electrons flow from negative terminal of a battery to the positive terminal because as the charge of electron is negative, it will get repelled by the negative terminal of the battery
Conventional flow actually assumes that the current flows out of the positive terminal, through the circuit and into the negative terminal of the battery
It actually says that direction of flow of current is in opposite direction to the direction of flow of electrons
The direction of current will not change even a resistor is placed in the circuit and it generates a potential difference across the resistor
But the current tries to move in such a way in which there will be less resistance to the flow

Answer:
the correct answer is the 60
made up of more than one cell.
Answer:
A. Distance over which the force is applied
Explanation:
As we know that in pulley system the mass of the car is balanced by the tension in the string
so here we will have
so here in order to decrease the force needed to lift the car we have to increase Distance over which the force is applied
So here if we increase the distance over which force is applied then it will reduce the effort applied by us in this pulley system as the torque will be more if the distance is more.
