Aclosely wound rectangular coil of 100 turns has dimensions of 27.0 cm by 50.0 cm . the plane of the coil is rotated from a position where it makes an angle of 37.0 ∘ with a magnetic field of 1.20 t to a position perpendicular to the field. the rotation takes 9.00×10−2 s . (note that the coil is perpendicular to the area vector of the coil.) what is the average emf induced in the coil?

Clothes dryer uses about 7 amps of current from a 240 volt line. how much power does it use?

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
