The wavelength of the radio waves is 3.04 cm.
<h3>Calculation:</h3>
λf = c
λ = c/f
where,
λ = wavelength
c = speed of light
f = frequency
Given,
f = 98.6 MHz = 98.6 × 10⁶
c = 3 × 10⁸
To find,
λ =?
Put the values in the formula,
λ = c/f
λ = 3 × 10⁸/98.6 × 10⁶
= 0.0304 × 10² m
= 3.04 cm
Therefore, the wavelength of the radio waves is 3.04 cm.

Answer:
anywhere between 100000 to about 400000 human years .
Explanation:
1 horsepower is equal to 746 W, so the power of the engine is

The power is also defined as the energy E per unit of time t:

Where the energy corresponds to the work done by the engine, which is

. Re-arranging the formula, we can calculate the time t needed to do this amount of work:
C. The sun is 400 times farther from Earth than the moon is.
Explanation:
because the acceleration is negative, this indicates a deceleration (or slowing down) . Hence we can say that:
The car is decelerating (slowing down), i.e its velocity is decreasing, at a constant rate of 5m/s².
