Explanation:
The total momentum of the system player+basketball must be conserved before and after the ball has been thrown.
Before throwing the ball, the total momentum of the system is zero, because can assume both the player and the basketball being at rest:
The total momentum after the ball has been thrown is instead the sum of the momenta of the the player and of the basketball:
where
is the player's mass
is the player's velocity
is the ball's mass
is the ball's velocity
For the conservation of momentum, we have
And the negative sign means that the player travels in the opposite direction to the ball.
According to Ohm's Law:
Where: V = Voltage
I = Current
R = Resistance
As you can see here, you can say that Current is directly proportional to Voltage and indirectly proportional to Resistance. This means that as the voltage increases, current increases and as the resistance increases, current decreases.
So in your scenario, if the voltage remains the same, but the resistance is doubled, that means that the current will be halved. So the answer to your question is 2. the current will drop to half of its original value.
