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 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,

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 .

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.

Newton's law of cooling holds good provided the temperature difference between the body and the surroundings is .

In an experiment of Newton's law or cooling the graph between the rate of cooling of the body and excess of temperature with the surrounding is ______

Newton’s law of cooling, holds good only if the temperature difference between the body and the surroundings is
