Not secure-gauss. vaniercollege. qc. ca integrated concepts: an mri technician moves his hand from a region of very low magnetic field strength into an mri scanner's 2.04 t field with his fingers pointing in the direction of the field. a) find the average emf induced in his wedding ring, given its diameter is 2.17 cm and assuming it takes 0.255 s to move it into the ield. mv b) what current is induced in the ring if its resistance is 0.0101 ω? c) what average power is dissipated? mw d) what magnetic field is induced at the center of the ring? what are the directions of the induced magnetic field and current, respectively, relative to the mri's field? a. into mri, counterclockwise b. out of mri, counterclockwise c. into mri, clockwise d. out of mri, clockwise

1point) a skydiver weighing 130 lb (including equipment) falls vertically downward from an altitude of 14,000 ft and opens the parachute after 20 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.85|v|0.85|v| when the parachute is closed and is of magnitude 17|v|17|v| when the parachute is open, where the velocity vv is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. find the speed of the skydiver when the parachute opens. speed is 150.6121788 ft/s find the skydiver's height when the parachute opens. height is 2338.98591 ft find the limiting velocity vlvl after the parachute opens. (think about whether this should be positive or negative.) vl=vl= 7.647 ft/s

How much force was applied to an object if was moved 2 meters and the work done on the object was 8 joules? a. 0.25 n b. 4 n c. 6 n d. 16 n
