Which branch of government has the power to ratify treaties?
That body is the United States Senate. Treaty ratification takes a super majority vote of 2/3.
Definition of emissive power and absorptive power of a black body?
Emissive power is defined as the energy radiated from a body per unit area per unit time at any given temperature.
What substance is most absorptive to visible light?
This ideal material is called "black body".
Is there any perfect black body in the universe?
No. The black body is an "ideal thing" or a construct, and there isn't anything that "perfect" in nature.
Is there exists any perfect black bodies in the universe?
There are no perfect black bodies on the universe. But there are a lot of them which can be approximated (with good precision) by the black body description.
What happens to radiant heat when it falls on a body?
The way a body reacts to incident radiation depends upon the absorptive, reflectivity and transitivity. These are functions of the type of material and its color. For example black color metal would reflect more radiation than a black coloured plastic.
How does the color of something affect radiant energy?
The color will determine if it can reflect light energy being a perfect black body that does not reflect and a perfect white body
What is a perfect black body?
A perfect blackbody absorbs all radiation incident on it and It emits electromagnetic radiation in the form of thermal radiation from its surface. OR A perfect blackbody is a perfect emitter and perfect absorber.
What is a perfectblack body?
If it is capable of emitting and absorbing radiations having wavelength right from 0 to infinite, then it is declared as perfect black body. Sun is a black body. Now it is in the emitting phase.
Why does some object appear black?
It's one of the colour. Black colour absorb all colour. A perfect black body radiates heat.
What surface emits heat radiation best?
A matt black surface is best. A theoretical perfect radiator is called a black body.
When blood levels of glucose amino acids and insulin are high and glycogenesis is occurring in the liver the body is in the?
absorptive state. (absorbed, used and stored)
Why a hole in the wall of cavity radiator is called a black body?
Black is the color which absorbs or radiates all frequencies equally. The perfect black body is only a theoretical object; in the real world there is always some limit to the frequency range. However, a hole in a cavity radiator comes close to being a black body.
