An electric heater working at 230 V produces 1000 J energy in one second. Calculate the resistance of the heating coil used in it.

When breast feeding is replaced by less nutritive food low in proteins and calories the infants below the age of one year are likely to suffer from

a calorie is a unit of heat or energy and it equals about 4.2J, where 1J=1kgm^2s^(-2) . suppose we employ a system of units in which the unit of mass equals alpha kg, the unit of length equals beta meter, the unit of time is second. show that a calorie has a magnitude 4.2alpha^(-1)beta^(-2)gamma^2 in terms of new units.

An electric heater working at 230 V produces 1000 J energy in one second. Calculate the heat generated by it when it works for 5 minute.
