Three conducting loops are situated side-by-side in the plane of the page. A clockwise current flows in the center loop B, and its magnitude is decreasing in time. The induced currents in loops A and C: A) flow in opposite directions,A clockwise, B counterclockwise) b)both flo...
A 100 gram resistive slider (thick line) moves without friction along a vertical U-shaped conducting track (thin line) that is 50 centimeters wide in a magnetic field of 5 Tesla as shown. The slider's resistance is 20 Ohms. It falls under the influence of gravity. What is ...
6.A current of 20 mA flows in a single circular loop with a radius of 2 meters. A uniform magnetic field of 1.2 T points parallel to the plane of the loop. What is the magnitude of the magnetic moment of the loop in A-m^2? b. What is the magnitude of the torque on the loop in ...
1.A proton travels at 4 x 10^6 m/s in a direction that is at an angle of 60 degrees to a magnetic field of 0.5 T. What is the magnitude of the force on the proton in Newtons? 2.What is the acceleration of the proton?
a proton flying to the east near the surface of the earth at 1000mls. what is the magnitude of the force the proton feels due to earths magnetic field
Two spherical conducting wires A and B are connected to the same potential difference. Wire A is three times as long as wire B, with a radius double that of wire B and resistivity doubles that of wire B. What is the power delivered to wire A to the power delivered to wire B?
a metal wire has a resistance of 8 Ohms at a temperature of 20 degrees. if the same wire has a resistance of 8.40 Ohms at 70 degrees. What is the resistance of this wire in Ohms when its temperature is -10 degree celsius
an insulating sphere of mass m and positive charge is attached to a string of height h and spring constant k. What is the tangent of the angle theta (tan theta) between the string and the vertical in terms of E,ke.q,m,and g?
a)If a Magnesium nucleus is fixed a distance away from a charge, what is the magnitude of the electrostatic force it experiences in Newtons (yes, it is a small force in Newtons)? b)If the charge is at the origin and the Magnesium nucleus is from the origin in the direction, at...
