A body cools in a surrounding of constant temperature `30^(@)C`. Its heat capacity is `2J//^(@)C`. Initial temperature of the body is `40^(@)C`. Assume Newton's law of cooling is valid. The body cools to `36^(@)C` in `10` minutes.
When the body temperature has reached `36^(@)C`. it is heated again so that it reaches to `40^(@)C` in `10` minutes. Assume that the rate of loss of heat at `38^(@)C` is the average rate of loss for the given time . The total heat required from a heater by the body is :
