A hot body placed in air is cooled down according to newton's law of cooling the rate of decrease of temperature being k times the temperature difference from the surrounnding Starting from `t =0` The time in which the body will lose half of the maximum heat is `(xLn2)/(2k)` Find the value of x .

A hot body placed in air is cooled down according to Newton's law of cooling, the rate of decrease of temperature being k times the temperature difference from the surrounding. Starting from t=0 , find the time in which the body will lose half the maximum heat it can lose.

A hot body placed in air is cooled down according to Newton's law of cooling, the rate of decrease of temperature being k times the temperature difference from the surrounding. Starting from t=0 , find the time in which the body will loss half the maximum heat it can lose.

A hot fbody placed in air is cooled down according to Newton's law of cooling, the rate of decrease of temperature being k times the temperature difference from the surrounding. Starting from t=0 , find the time in which the body will loss half the maximum heat it can lose.

A hot body placed in air is cooled down according to Newtons Law of cooling, the rate of decrease of temperature being beta times the temperature difference from the surrounding. Starting from t = 0, the time in which the body will loose half the maximum heat it can loose,

Derive Newton's law of cooling to show that the rate of loss of heat from the body is proportional to the temperature difference between the body and its surroundings.

In the circuit shown the resistance R is kept in a chamber whose temperature. is 20^(@) C which remains constant. The initial temperature and resistance of R is 50^(@)C and 15 Omega respectively. The rate of change of resistance R with temperature is (1)/(2)Omega//^(@)C and the rate of decrease of temperature of R is In (3//100) times the temperature difference from the surrounding (Assume the resistance R loses heat only in accordance with Newton's law of cooling) If K is closed at t = 0, then find the (a) value of. R for which power dissipation in it is maximum. (b) temperature of R when power dissipation is maximum (c) time after which the power dissipation will be maximum
