(a)The frequency of the broadcast is 1.2 × 10⁻¹⁰ Hz.
(b) It is a FM radio station.
(a) The wavelength of electromagnetic radiation = 1 quarter mile
= 0.25 mi
∴ Wavelength = Speed of light / Frequency
λ = v / f
f = v / λ
= (299792.458 m/s ) / 0.25 mi
= 1199169.832 Hz
= 1.2 × 10⁻¹⁰ Hz
Therefore, the frequency of the broadcast is 1.2 × 10⁻¹⁰ Hz.
(b) The station is FM as it ranges in a higher spectrum from 88 to 108 MHz. (OR) 1200 to 2400 bits per second. The signal that is going to be sent in FM modulates the frequency of a radio wave known as the "carrier" or "carrier wave." The phase and amplitude stay constant.
Compared to AM, FM is less prone to interference. However, physical obstructions have an impact on FM broadcasts. Due to its greater bandwidth, FM has better sound quality. twice the result of the frequency variation and the modulating signal frequency.

Answer:
Speeed
Explanation:
The speed of an object is defined as the rate of change of distance:
where
d is the distance covered by the object
t is the amount of time needed to cover that distance
Speed is measured in meters per second (m/s). It should be noted that speed is a scalar quantity, so it only has a magnitude (and no direction).
Answer:
48 m
Explanation:
An object is said to be moving in uniform motion if its velocity is constant.
For an object in uniform motion, its average speed is given by the equation:
where
v is the average speed
d is the distance covered
t is the time taken
For the object in this problem, we have:
v = 6.0 m/s is the average speed
t = 8.0 s is the time taken
Solving for d, we find the distance traveled:
