<u>Answer:</u>
Speed of Hawk's shadow on the level ground = 3.29 m/s
<u>Explanation:</u>
When the sun is directly above the head of hawk shadow will be directly below hawk. So the speed of hawk's shadow will be equal to speed of hawk's in X -direction.
Velocity of hawk = 5.35 m/s
Angle from horizontal = 52.00⁰
Horizontal component = 5.35 cos 52.00⁰ = 3.29 m/s
So speed of hawk's shadow = 3.29 m/s
Answer:
Answer :- In a light wave the property of wave which tells about the color of light is it's Wavelength .
Wavelength is the distance between one crest and one through , also it is the distance after which the wave repeat itself !
It's SI unit is meter !
It is scalar quantity !!
Different Wavelength of light have different color !!
• VIBGYOR
i.e, Violent , Indigo , Blue , Green , Yellow Orange, and Red along with their shades are the colors which we can see !!
• They almost range from 400nm to 700nm ( visible range of light ) !!
Answer:
19.2 m/s
Explanation:
The train is moving at 18 m/s and you are walking in the same direction (east) so the speeds are added
18 + 1.2 = 19.2
If you were walking backwards (west) your velocity with respect to the ground would be
18 - 1.2 = 16.8
Answer:
10 ms^2
Explanation:
this is because F =MA
thus, 300N divided by 30 = 10 ms^2
