When a second identical bulb is added in series to a circuit with a single bulb, the resistance of the circuit
1 answer:
Answer:
Will double
Explanation:
The total resistance of a circuit with n resistors in series is equal to the sum of the individual resistances:
In this problem, we have a circuit with initially one light bulb of resistance R, so the total resistance of the circuit is:
Later, a second identical bulb (so, same resistance R) is added in series to the circuit; so applying the previous formula, we see that the new total resistance is
So, the resistance has doubled.

Answer:
Uncertainty in position of the bullet is
Explanation:
It is given that,
Mass of the bullet, m = 35 g = 0.035 kg
Velocity of bullet, v = 709 m/s
The uncertainty in momentum is 0.20%. The momentum of the bullet is given by :
Uncertainty in momentum is,
We need to find the uncertainty in position. It can be calculated using Heisenberg uncertainty principal as :
Hence, this is the required solution.
