Values appropriate for the earth''s magnetic field

Reference no: EM13544621

Assume the magnitude of the magnetic field outside a sphere of radius R is B = B0(R/r)^2, where B0 is a constant. (a) Determine the total energy stored in the magnetic field outside the sphere. (b) Evaluate your result from part (a) for B0 = 5e-5 T and R = 6e6 m, values appropriate for the Earth's magnetic field.

What is the work done by the force of gravity : A 255 kg piano slides 4.2 m down a 30° incline and is kept from accelerating by a man who is pushing back on it parallel to the incline (Fig. 6-36). The effective coefficient of kinetic friction is 0.40 Figure 6-36

What is the magnitude of the EMF in millivolts : An astronaut who is repairing the outside of her spaceship accidently pushes away a 98.9-cm-long steel rod, which flies off at 10.5 m/s, never to be seen again. As it happens, the rod is oriented perpendicularly to the magnetic field in that region o..

Find the work done by the dogs after pulling the sled : A 100 kg sled is slid across a smooth ice field by a group of four dogs tied to the sled pulling with a 350 N force along a rope at an angle of 20 degrees above the horizontal. (a) If the sled travels at a constant speed, find the drag force on the s..

What is the magnitude and direction of the velocity of m2 : A cart of mass m1 = 0.500 kg moves with a velocity of 0.900 m/s to the right on a frictionless track. It collides with another cart of mass m2 = 0.500 kg at rest. Car m1 stops and m2 moves in the direction that m1 was traveling. What is the magnitude..

Charge on the capacitor and the current in the circuit : An LC circuit like the one in Figure CQ32.8 contains an 82.0 mH inductor and a 17.0 micro Farad capacitor that initially carries a 180 micro Coulomb charge. The switch is open for t

Determine the radius of curvature of p of the turn : An airplane, traveling at a constant speed of 50 m/s, is executing a horizontal turn. if the plane is banked at theta = degrees, when the pilot experiences only a normal force on the seat of the plane, determine the radius of curvature of p of the tu..

Power is required of force motor exerts on cab via cable : A fully loaded, slow-moving freight elevator has a cab with a total mass of 1150 kg, which is required to travel upward 49 m in 3.1 min, starting and ending at rest. The elevator's counterweight has a mass of only 1025 kg, and so the elevator motor m..

Other forces also act on the particle : Force on a Particle A force F = (4.0 N)i + (c N)j acts on a particle as the particle goes through displacement d = (4.0 m)i - (2.0 m)j. (Other forces also act on the particle.) What is the value of c if the work done on the particle by force F is eac..
