Aquestion for the physicists out there:
during a thunderstorm, the potential difference between the thunderclouds and the ground builds up to v. in each stroke of lightning, 30c of charge passes between the thunderclouds and the ground. lightning strokes to the ground occur, on average, and 2 minute intervals.
calculate:
i) the average current between the thunderclouds and the ground,
ii) the energy transferred in each stroke of lightning.
i already know the answer, i'm just seeing who here is good at physics ; )

An equinox occurs when a. neither end of earth's axis is tilted toward or away from the sun. b. the north end of earth's axis is tilted away from the sun. c. the north end of earth's axis is tilted toward the sun. d. earth's axis is parallel to the sun's rays. select the best answer from the choices provided a b c d

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

Aspring has a natural length of 8 m. if a 12-n force is required to keep it stretched to a length of 10 m, how much work w is required to stretch it from 8 m to 16 m? (round your answer to two decimal places.)
