Its tangential speed is constant although its velocity is changing. As the object changes direction, it results in a changing of positive and negative signs of the velocity. Although, the magnitude of the velocity (speed) is not changing.
The answer would be a radio wave
Answer:
16.7 s
Explanation:
T= <u>Vf - Vo</u> a= <u>F</u>
a m
4,500 / 3000 = 1.5 (a)
30 - 5 / 1.5(a) = 16.7 s
Answer:
Explanation:
We need to find the frequency of green light having wavelength o
. It can be calculated as follows :
So, the required frequency of green light is equal to 
.
A water wave is an example of a mechanical wave. A wave that can travel only through matter is called a mechanical wave.
