The vertical velocity is affected by the acceleration of gravity (ignoring the effects of air resistance usually)
The wavelength of the radio wave is 0.303 m.
<h3>
Wavelength</h3>
The wavelength of the wave is the distance traveled by the wave.
c = fλ
where;
- c is speed of light = 3 x 10⁷ m/s
- f is frequency
- λ is wavelength
λ = c/f
λ = (3 x 10⁷ ) / (99 x 10⁶)
λ = 0.303 m
Thus, the wavelength of the radio wave is 0.303 m.

Answer:
Explanation:
Distance traveled by light = 2 x 550 m = 1100 m
time taken by light to travel this distance = 1100 / 3 x 10⁸
= 366.67 x 10⁻⁸ s
angle between two consecutive slots = 2π / 500 rad
= .004π
angular velocity of wheel = angle moved / time taken
= .004π / 366.67 x 10⁻⁸
= 1091π radian / s
b ) linear speed of a point on the edge of the wheel
= ω R , r is radius of wheel , ω is angular velocity.
= 1091π x 5 x 10⁻²
= 1712.8 m /s
I believe the correct answer is d. thermosphere.
