C.3 a) A square wire loop 8 cm on a side is perpendicular to a magnetic field of 5·10-3T. C.3 b) Calculate the magnetic flux through the loop? C.3 c) The field drops to 0 in 0.1s. Calculate the average emf which is induced in the loop during this period of time?

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)

In an experiment, how can i change human errors? be specific.

The law of reflection states that the angle of reflection is equal to the angle of
