Answer:
Every object has a different density and therefore carries different properties. When rays of white light strike an object, each ray light strikes the object with different frequency and therefore is absorbed and reflected differently from the host object.
In case if all the frequencies are absorbed by the object, it turns out to be black in color. Whereas on the other hand, if it is a mix of absorption and reflection, it makes different colors based on its frequencies and other properties of the object.

Explanation:
I legit just had this question on my homework.
Answer:The typical power plant burns three units of fuel to generate just one unit of electricity. Renewable sources, such as wind and solar, burn no fuel and release no greenhouse gases. They are far more effective at converting energy into electricity, keeping waste minimal, while saving money
