When a wire is made shorter, the resistance decreases.
When a wire is made thinner, the resistance increases.
speed at end is accn of gravity x time

Answer:
Focal length, f = 16 cm
Explanation:
Image distance, v = 24 cm
Object distance, u = -48 cm
We need to find the focal length of the lens. It can be determined using the lens formula as :


f = 16 cm
So, the focal length of the converging lens is 16 cm. Hence, this is the required solution.
