As a new electrical technician, you are designing a large solenoid to produce a uniform 0.170 TT magnetic field near the center of the solenoid. You have enough wire for 4000 circular turns. This solenoid must be 52.0 cm long and 2.80 cm in diameter. What current will you need to produce the necessary field?

Arock collection comes from which part of earth?

What are similarities and differences of reflection, refraction, diffraction and absorption?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
