The voltage across an element is v(t) = 16e-8t v. the current entering the positive terminal of the element is i(t) = 4e-3t a. find the energy absorbed by the element in 0.055 s starting from t = 0.

Explain using examples, what is simple harmonic motion and why it is an important area of study in physics.

25pts the diagram shows the positions of the sun, moon and earth during spring tides, when the high tides are at their highest and low tides at their lowest. what is it about these positions that causes these high and low tides?

Athermometer is removed from a room where the temperature is 70° f and is taken outside, where the air temperature is 10° f. after one-half minute the thermometer reads 60° f. what is the reading of the thermometer at t = 1 min? (round your answer to two decimal places.) ° f how long will it take for the thermometer to reach 30° f? (round your answer to two decimal places.)
