The horse is rolling on wheels while the horse's hooves have traction to the ground.
The wavelength of a microwave of 3 x 10^9 Hz frequency is 0.1 m.
The wavelength of a microwave of 3 x 10^9 Hz frequency is calculated using the equation λ = c/f, where λ is the wavelength, c is the speed of light, and f is the frequency.
The speed of light is approximately 3 x 10^8 m/s. Therefore, the wavelength of a microwave of 3 x 10^9 Hz frequency can be calculated as follows:
λ = 3 x 10^8 m/s/3 x 10^9 Hz
= 0.1 m.
Therefore,the wavelength of a microwave of 3 x 10^9 Hz frequency is 0.1 m.
Microwaves are electromagnetic waves that have a frequency between 300 MHz to 300 GHz and a wavelength from 1 mm to 1 m. Microwaves have a variety of uses, including communications, radar, and cooking. Microwave radiation is absorbed by water, fats, and sugars, which is why it is used for cooking.
The frequency of a microwave is usually expressed in megahertz (MHz) or gigahertz (GHz). One megahertz is equal to one million hertz and one gigahertz is equal to one billion hertz. The frequency of a microwave determines its wavelength; the higher the frequency, the shorter the wavelength.

Explanation:
We know that :
u = 29 mph = 12.96 m/s
S = 471 ft = 143.5 m
t = 8.5 sec
143.5 = 12.96 * 8.5 + 1/2 * a * 72.25
a = 66.68 / 72.25
a (Acceleration) = 0.92 m/sec^2
= 3.01 ft/sec^2
