A piece of wire with mass per unit length 78 runs horizontally at right angles to a horizontal magnetic field. A 6.5 current in the wire results in its being suspended against gravity. What is the magnetic field strength?
Near Earth the density of protons in the solar wind(a stream of particles from the Sun) is 8.70 cm-3 and their speed is 470 km/s. Find the current density of these protons.
Calculate the magnitude of the forces due to an electric dipole of dipole moment 3.6x10^-29 Cm on an electron 25 nm from the center of the dipole, along the dipole axis. Assume that this distance is large relative to the dipole's charge separation
The sound of the blow twice (once through the air and once through the rod), with a 332 ms interval between them. How long is the rod?
A rectangular air mattress is 2.00 m long, 0.500 m wide, and 0.100 m thick. If it has a mass of 2.8 kg, what additional mass can it support in water? The acceleration of gravity is 9.8 m/s2
The time it takes to complete 1 cycle, T. Units? [s] Frequency: # of complete cycles per unit time, f. Units? What is the amplitude, period, and frequency of the following motion? Period?
A 29 g bullet is fired straight upward into an at rest 1.40kg block and the bullet is embedded in the block. The velocity of the bullet is 510 m/s. Show the conservation of mechanical energy and conservation of momentum are inconsistent before an
In a diesel engine, the piston compresses air at 304 K to a volume that is 0.0629 of the original volume and a pressure that is 48.2 times the original pressure. What is the temperature of the air after the compression?
Four 8.0 kg spheres are located at the corners of a square of side 0.58 m. Calculate the magnitude and direction of the gravitational force exerted on one sphere by the other three.
