For a short time after a wave is created by wind, the height of the wave can be modeled using y = a sin 2 pi t/ t , where a is the amplitude and t is the period of the wave in seconds.
how many times over the first 5 seconds does the graph predict the wave to be 2 feet high? show work

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

hello, never fear papaguy is here!

step-by-step explanation:

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
