What are the factors does the heat emitted by a hot body depend?
The heat emitted by a hot body depends on its temperature, surface area, and emissivity. The Stefan-Boltzmann law states that the total amount of heat radiation emitted by a body is directly proportional to the fourth power of its absolute temperature.
When the distance travelled by a body is directly proportional to time then it is travelling with?
constant speed.
Name one quantity that must be know in order to determine the amount of heat associated with a body?
There are three: Energy absorbed by a body is directly proportional to the rise in temperature of a body Heat energy absorbed by a body is directly proportional to the mass of the body Heat energy absorbed by a body depends upon its nature and is commonly called specific heat capacity.
How does thermal radiation change as a body emitting it changes temperature?
As a body's temperature increases, its thermal radiation also increases. This is because thermal radiation is directly proportional to the fourth power of temperature according to the Stefan-Boltzmann law. This means that a small increase in temperature results in a significant increase in the amount of thermal radiation emitted.
When the distance travelled by a body is directly proportional to the time than the body is said to have?
Constant speed. (Acceleration isn't necessarily zero, and velocity isn't necessarily constant.)
What is newton's cooling law?
rate of change of cooling is directly proportional to the temperature distance between the body and the surrounding at the instant.

Is there any option for retun back from Newtons third law to second law?
The rate of change of momentum of body is directly proportional to the force,and the body moves in the direction of force applied.
Why the newtons law of cooling is not valid for high temperature?
According to the Wikipedia article, a non-mathematical explanation of Newton's Law of Cooling is: "The rate of heat loss of a body is proportional to the temperature difference between the body and its surroundings."In other words, it is assumed that the rate of heat loss will increase linearly with temperature. This is basically correct if you consider only conduction; however, in the case of radiation, the radiation emitted by a body is proportional to the fourth power of the absolute temperature (for example, temperature measured in Kelvin). This will give you a curve, not a straight line; for small temperature intervals, you can approximate this with a straight line, but it will not be exact.

How does oxygen consumption affect metabolic rate?
Oxygen consumption is directly proportional to metabolic rate. As the body metabolizes nutrients to produce energy, it requires oxygen to carry out this process. Therefore, an increase in oxygen consumption indicates a higher metabolic rate, while a decrease in oxygen consumption indicates a lower metabolic rate.
What is newtons law of cooling?
AnswerNewton's law of cooling describes the rate an object will cool at when placed in surroundings of lower temperature. The law is derived by some basics of calculus, but based on one fact: the rate of cooling of an object is proportional to the difference in temperature between the surroundings and the object. It does assume some things and simplifies others (such as where the energy goes after leaving our object and the energy flow through the object between areas with different temperature - inside and outside) but is generally a very good approximation. Various forms of the original equation can be used depending on purpose, but solving is a lot simpler. dTt/dt = -ΔTt/t0, where Tt is the temperature of the object at a given time, t is time, and t0 is a time constant. This is a differential equation, and can be integrated to give us a solution: ΔTt = ΔT0 * e-rt, where r = 1/t0 is the time constant and e is the natural log base.
