Answer:
(a) and (b)
Explanation:
Energy is the capacity to do work, and exists in various forms. These forms can be converted one to another by the use of appropriate means. Some examples are sound, mechanical, solar, light, which causes the sensation of vision, etc. energy is measured in Joules (J).
The rate of transfer of energy is called power.
i.e Power =
It is measured in Watts (W).
When a white light is disperses into its colors, gray and black are not part of the colors. And a black sometimes could be as a result of the absorption of all other colors of light.
Answer:
The force constant of the spring, k = 3.15N/m
The maximum velocity Vmax = 1.44m/s
amax = 4.21m/s
Explanation:
The amplitude I half the distance between the points 1.06m and 2.05m. = 0.495
The complete solution can be found below in the attachment.
Thank you very much for e reading and I hope this is helpful to you.
the reason why sound travels faster in solid is because the molecules in solid is more close to each other and they allow the waves of the sound to travel quickly or easily. and same reason why the sound travels fast in liquid that gas, it's because the molecules in liquid is closer to each other than the molecules in gas but they're not as close as solid hence why solid is the fastest at traveling sound
