You are given a certain volume of copper from which you can make copper wire. to insulate the wire, you can have as much enamel as you like. you will use the wire to make a tightly wound solenoid 20 cm long having the greatest possible magnetic field at the center and using a power supply that can deliver a current of 5 a. the solenoid can be wrapped with wire in one or more layers. a) should you make the wire long and thin or shorter andthick? explain.

would it be shorter and thick because b= μ0ni is tha magnetic field at the center (n=n/l)so if you wrap it a greater number of time and have a shorterlenght the b would be greater?

b) should you make the solenoid radius small or large? explain.

radius small b/c using same equationn=n/2πr so a smaller r the greater n and the greaterb

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.

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.
