A uniform electric field of increasing strength also passes through the ring, parallel to the wire. The magnetic field through the ring is zero. a. At what rate is the electric field strength increasing?
b. Is the electric field in the direction of the current or opposite to the current?

What is friction? how does it affect the motion of an object?

Matter that emits no light at any wavelength is called

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
