Answer:

1.

Resistance of wirr before cutting = R

Resistance of wires after cutting = R'

R' = 5/R + 5/R + 5/R + 5/R + 5/R

R' = 25/R

R'/25 = R

R / R' = 1/25

(a) 1/25 is correct.

2.

(b). IR^2

3.

P = V× I

100w = 110 × I

I = 100/110

= 10/11

Now, P = VI

= 110 × 10/11

= 10 × 10 = 100W

Hope it helps..
