A water wave is 3m tall. Taking a picture of the wave, you measure 7m between peaks. With your stopwatch, you measure .8 seconds between a peak and a trough. Write the wave function for this water wave. Ignore the initial phi.

The water wave function is given as                                

Explanation:

Water waves are surface waves, which is a mixture of longitudinal and transverse waves.

The general wave equation is given as;

where;

A is the amplitude = 3 m

λ is one wavelength = 7 m

t is period for one complete oscillation, T = 8 s

v is the velocity of the wave;

for each period, the wave  travels one wavelength, v = λ/T = 7/8 = 0.875m/s

Therefore, the water wave function is given as

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.

explanation:

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)
