Acircular loop made from a flexible, conducting wire is shrinking. its radius as a function of time is r = r0e-bt. the loop is perpendicular to a steady, uniform magnetic field b. find an expression for the induced emf in the loop at time t.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

sodium is solid at rt

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
