Answer:
Yes. Check reason below
Explanation:
Yes the color of materials has a role in regulating the heat. This is because colors vary in their abilities to absorb heat energy.
The ability of colors to absorb heat decreases with a decreasing wavelength. As the wavelength decreases, the color becomes cooler because of a decrease in the rate of heat absorption. Red, Orange, Yellow, Green, Blue, Violet ( In order of decreasing wavelength)
The higher the ability to absorb heat energy, the hotter the body is. Black color absorbs more heat than other colors, hence is hotter than other colors. Colors that have high reflective ability ( ie. reflect back a large portion of the light that falls on them) are a lot cooler than those with high absorptive ability. An example is white ( a combination of all visible lights)
Therefore, in designing the seating of a wheel the color should be highly considered for heat regulation.
Slower towards the black hole
Answer: B. Galaxy (happy to help)
Explanation:
Kinetic energy has a formula
Kinetic energy = 1/2 * mass * velocity ^2
