Answer:An object that absorbs ALL radiation falling on it, at all wavelengths, is called a blackbody. When a blackbody is at a uniform temperature, its emission has a characteristic frequency distribution that depends on the temperature. ... As its temperature increases further it becomes yellow, white, and ultimately blue-white
Explanation:
Because there is water everywhere by which the water gets hot and vaporised so that's why near the sea temperature is low.
The smallest unit of an element that has all the properties of the element is an atom. This has all the properties of an atom, including the particles.
The position of the mass is given by (in cm):

The velocity is the derivative of the position:

Substituting t=0.40 s, we can find the velocity at this time:
