Answer:absorbs and emits electromagnetic radiation at all wavelengths
Explanation:
A blackbody is a believed to be a perfect absorber and reflector of radiation. Blackbody, in physics, refers to a surface that absorbs all radiant energy that falls on it. It is supposed that because incident visible light will be absorbed rather than reflected, the surface will appear black.
Explanation:
it is reflected all the other colors such as red is absorbed
Answer:
Mass of banana is 
Kg
Explanation:
Step 1: Determine the equation of speed of an object moving in an harmonic motion
Speed of moving in an harmonic motion is given by
Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.
In this question , 
because only at this position maximum speed occurs
So the simplified equation becomes -
OR
Substituting the given values in above equation we get -
Assume spring constant is 
N/m
Mass of banana is Kg
Density - Describes how compact the matter is in a substance. ...
Color - Describes how light reflects off a substance.
Luster - Describes how shiny a substance is. ...
Texture - Describes the smoothness/roughness of a substance.
Odor - Describes the smell of a substance.
Answer: The color of an image is equal to the color of the item forming the picture. When you have a take a observe your self in a mirror, the color of your eyes would not alternate. The reality that the color is equal is proof that the frequency of light would not alternate upon reflection.
