A surfer is riding a wave with an amplitude of 6 feet and a period of 24 feet. If the wave completes a period in 8 seconds.The speed of the surfer is 3ft/sec.
A wave's amplitude is defined as its largest displacement on either side of its mean location.
The quantity of oscillations a wave makes in a second is referred to as frequency of wave.
The amount of time it takes to complete one vibration, from A to B, is referred to as time period.
As we know,
ν = λf
where, ν = speed
λ = wavelength
f = frequency
also,
Putting in the values in equation ν = λf gives us,
ν = 24 × ( period of wave must means wavelength of 24ft)
ν = 3ft/sec.

Human building a drainage system could affect the water cycle because :
C. water would be directed to a new location because of the drains
This could potentially changed the natural occurrence that usually happened within the water cycle
hope this helps
Answer:
Rusting!
Explanation:
Rusting is a chemical reaction because it is the process of oxidation of a metal.
Answer: The terrestrial planets, Mars, Earth, Venus, and Mercury all have relatively high densities and low gas content, e.g., they are small and rocky. The Jovian (or giant planets), Jupiter, Saturn, Uranus, and Neptune, are very large and have rather low densities, e.g., they are gaseous.

Answer: Microwaves
Explanation:
RADAR stands for radio detection and ranging. Radio waves range from 300 GHz to 30 Hz. Modern radar uses higher frequency of waves for detection. These waves are microwaves (300 MHz-300 GHz). Microwaves are types of radio waves and are used in the radar detection.
The electromagnetic wave which has highest frequency is gamma wave but it is not used for radar detection.
Hence, the correct answer is microwaves are the type pf radio waves which have the highest frequency and are used in radar detection.
