The wave height is equal to twice the _____.wave period wave height wave amplitude wave velocity wavelength
Archy [21]

The wave height is equal to twice the amplitude of the wave.

The wave height of a wave of given wave with amplitude, period and wavelength is equal to twice the amplitude of the wave.

The amplitude of a wave is the maximum displacement of the wave, starting from the zero position of the wave. The wave height measures twice the maximum displacement of the wave.

Thus, we can conclude that the wave height is equal to twice the amplitude of the wave.

An airplane maintains a speed of 627 km/h relative to the air it is flying through as it makes a trip to a city 787 km away to t
amid [387]

Answer:1.33 hr

Explanation:

Given

Speed of airplane relative to air=627 km/h

Distance traveled =787 km

Speed of wind=38.4 km/h

Wind is blowing in opposite direction therefore net speed is

v_{net}=627-38.4=588.6 km/h

thus time taken is

t=\frac{distance}{speed}

t=\frac{787}{588.6}=1.33 hr
