Answer:
Mars
Explanation:
The closest planet to the sun is Mercury, then follows Venus, then our Earth, and in fourth place comes Mars, which therefore becomes the outermost of he four mentioned planets
Answer: wavelength is equal to 150 m
Explanation: To solve for the wavelength we will use the formula of frequency which is the ratio of wave speed per unit wavelength and derive to find wavelength.
wavelength = wave speed / frequency
= 1500 m/s / 10 Hz
= 150 m
