v = 5 m s^(-1) W = mg = 100 N m = 10 kg Kinetic energy ??

A circuit has a fuse of 5 A. What is the maximum number of 100 W (220 V) bulbs that can be safely used in the circuit ?

In a large building, there are 15 bulbs of 40 W, 5 bulbs of 100 W, 5 fans of 80 W and 1 heater of 1 kW. The voltage of electric mains is 220 V. The minimum capacity fo the main fuse of the building will be :

A circuit has a fuse having a rating of 5 A. What is the maximum number of 100 W-220 V bulbs that can be safely connected in parallel in the circuit?

The resistance of a certain paltinum resistance thermomter is found to be 2.56 Omega at 0^(@)C and 3.56 Omega at 100^(@)C . When the thermometer is immersed in a given liquid, its resistance is observed to be 5.06 Omega . The temperature of the liquid
