<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.
It indicates that you should proceed with caution. You should slow down and be prepared to stop to safely navigate this intersection.
Answer:
Mass of 17.854 kg is only attached to the spring
Explanation:
We have given time period in first case is 22 sec
Let initially mass is m
After 22 kg are added the period becomes 33 sec
Time period of spring mass system is
, here m is mass and k is spring constant
From the relation we can see that
Squaring both side
m = 17.584 kg
So mass of 17.854 kg is only attached to the spring
Answer:
0.6
Explanation:
Angular acceleration is equal to Net Torque divided by rotational inertia, which is the rotational equivalent to Newton’s 2nd Law. Therefore, angular acceleration is equal to 3.6/6 which is 0.6. Hope this helped!
