An engineer is testing an experimental engine for its efficiency. The engineer runs the

engine

under load and measures its output at intervals of thours. At the beginning of the test the

engine was outputting 2900 watts. At the first interval the engine was down to 2892.75

watts. Write an exponential decay formula to model this situation.

i dont know sorry

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
