For a research project, a student needs a solenoid that produces an interior magnetic field of 0.0500 T. She decides to use a current of 1.00 A and a wire 0.500 mm in diameter. She winds the solenoid in layers on an insulating form 1.00 cm in diameter and 10.0 cm long.
1) Determine the number of layers of wire needed.
2) Determine the total length of the wire.
Suppose you want to connect your stereo to remote speakers; it requires 20 m length of wire per speaker, how does the resistance changes
A muon is produced by a collision between a cosmic ray and an oxygen nucleus in the upper atmosphere at an altitude of 50 km, What is the velocity of a muon at the surface
A point charge, q1 = +2C, is placed at the origin (0m,0m), a second point charge, q2 = -3C, is located at (2m, 0m), and a third point charge, q3 = -4C, is located at (0m, 3m)
The coefficient of kinetic friction between a 20 Kg box and the floor is 0.40. How much work does a pulling force do on the box in pulling it 8.0 m at the constant speed? The pulling force is directed 390 above the horizontal.
Much of the material making up Saturn's rings is in the form of tiny dust grains having radii on the order of 10-6 m. These grains are located in a region containing a dilute ionized gas, and they pick up excess electrons. As an approximation, sup..
If the balloon is 24.9 cm in diameter when child loses it, what is its diameter at an altitude of 1510 m? Assume that the balloon is very flexible and so surface tension can be neglected.
A landing airplane makes contact with the runway with a speed of 78.0 m/s and moves toward the south. After 18.5 seconds, the airplane comes to rest. What is the average acceleration of the airplane during the landing?
A 60.0 resistor is connected in parallel with a 116 resistor. This parallel group is connected in series with a 20.0 resistor. The total combination is connected across a 15.0 V battery.
