The two-loop wire circuit is 112.688 cm wide and 75.125 cm high. The wire circuit in the figure is located in a magnetic field whose magnitude varies with time according to the expression B = (0.001 T/s) t and its direction is into the page. Assume The resistance per length of the wire is 0.089 Ω/m.
When the magnetic field is 0.5 T, find the magnitude of the current through middle leg PQ of the circuit.
Answer in units of μA.
A fluid in an insulated, flexible bottle is heated by a high resistance wire and expands. If 9kJ of heat is applied to the system and it does 5kJ of work, how much does the internal energy change?
A rotating cylinder about 12.00 km in length and 8.00 km in diameter is designed to be used as a space colony. With what angular speed must it rotate so that the residents on it would experience the same acceleration because of gravity on Earth.
A positively charged light metal ball is suspended between two oppositely charged metal plates on an insulating thread as shown below. After being charged once, plates are disconnected from the battery. define the behavior of the ball.
How much work must be done to bring three electrons. calculate the mass of an ice cube.
A person is standing at the edge of the water and looking out at the ocean (see figure). The height of the person's eyes above the water is h = 1.8 m, and the radius of the Earth is R = 6.38 x 106 m. (a) How far is it to the horizon? In other word..
When the afternoon Sun reaches an angle of 30° above the horizon, sunlight ceases to clarify any part of the bottom of the tank. How deep is the tank.
find out the magnitude of their acceleration. If the blocks move determine the magnitude of the tension in the string. If the blocks do not move determine the sum of magnitude of the forces of friction acting on the blocks. Show all the work.
Blocks with masses of 2 , 4 , and 6 are lined up in a row on the frictionless table. All three are pushed forward by a 56 force applied to the 2 block. How much force does the 4 block exert on the 6 block.
how fast does it move after the bullet emerges. The critical angle of refraction for calcite is 68.4^0 when it forms a boundary with water. use this information to find the speed of light in calcite.
The density of free electrons in gold is 5.90 x 10^28 m-3. The resistivity of gold is 2.44 x 10-8 at a temperature of and the temperature coefficient of resistivity is 0.004 ()-1. A gold wire, 1.30mm in diameter and 27cm long, carries a current of..
Sam, who's mass is 79 kg, takes off across level snow in his jet powered skis. The skis have a thrust of 204 N and a coefficient of kinetic friction on snow of 0.1. Unfortunatately the skis run out of fuel after only 13 s.
explain the magnitude of the centripetal acceleration. At what two locations on the x-axis (xpositive, xnegative) is the potential zero.
