Calculate the energy needed to heat 4 kg of water from 25°C to 45°C. heat = 80 Kcal 100 Kcal 280 Kcal 180 Kcal

answer

c, on a nylon carpet in a dry area. give me brainliest

explanation:

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
