<u>The color of an object is related to the wavelengths of light that are reflected and the wavelengths that are absorbed because:</u>
Visible light is light that has wavelengths that can be detected by the human eye. The wavelength of visible light determines the color that the light appears. The light with the longest wavelength is red, and light with the shortest wavelength is violet.
An opaque object doesn’t allow light to pass through it. But, it reflects or absorbs the light that strike it. Some objects like the leaves reflect one or a few wavelengths of visible light and absorb the others. The reflected wavelengths are used to find the color of an object as it is seen by the human eye. Example: The leaves are in green as they reflect green light and absorb the other wavelengths light. A transparent or translucent material, such as window glass, transmits some or all of the light that strikes it. This means that the light passes through the material rather than being reflected by it. Hence, we see the material because of the transmitted light. So the wavelength of the transmitted light is used to find the color that the object appears.
By definition, we have that the gravitational force is given by:
Where,
G: gravitational constant
m1: mass of object number 1
m2: mass of object number 2
r: distance between both objects.
Therefore, for the gravitational force to increase, the following conditions must be met:
1) Increase the mass of the objects so that the numerator of the equation is greater.
2) Decrease the distance between the objects so that the denominator of the equation is smaller.
Answer:
A change that will always result in an increase in the gravitational force between two objects is:
increasing the masses of the objects and decreasing the distance between the objects
I believe you are correct, it is B: Diagnostic Services.
Diagnostic services are services like the staff at hospitals and the people who run machines that are related to medical needs.
<em>If this is incorrect, please, don't refrain to tell me.</em>
The big bang theory describes and claims that the universe has been created through cosmic expansion originating from a single point.
Where it was explained that the nature of now objects in space being in constant space was due to once a high density and high density point produce a scattering or explosion of the cosmic energy . Other theories have also supported this theory originally and first documented by Georges Henri Joseph Édouard Lemaître an astronomer and physicist.
