An aluminum wire with a diameter of 0.105 mm has a uniform electric field of 0.295 V/m imposed along its entire length. The temperature of the wire is 55.0° C. Assume one free electron per atom.
(a) Use the information in this Table of Resistivities and Temperature Coefficients to determine the resistivity of aluminum at this temperature.
(b) What is the current density in the wire?
J = MA / m2
(c) What is the total current in the wire?
I = mA
(d) What is the drift speed of the conduction electrons?
vd = µm/s
(e) What potential difference must exist between the ends of a 2.50-m length of the wire to produce the stated electric field?
An automobile club plans to race a 780 kg car at the local racetrack. The car needs to be able to travel around several 170 m radius curves at 85 km/h. What must the banking angle of the curves be so that the force of the pavement on the tires of the..
What is magnitude of the unknown force
A 4 kg mass is hung from a string which is wrapped around a cylindrical pulley (a cylindrical shell). If the mass accelerates downward at 4.90 m/s2, what is the mass of pulley.
When 50-ml of a liquid is heated through 20 degree centigrade, its apparent expansion was 0.5 ml. If the coefficient of linear expansion of the container is 9 x 1/1000000 per K, find the coefficient of real expansion of the liquid.
how much weight must each man support. by how much would the temperature of the air rise over a period of 2.0 h due to the metabolism of the people.
David is driving a steady 21 m/s when he passes Tina, who is sitting in her car at rest. Tina begins to accelerate at a steady 2.20 m/s^2 at the instant as David passes.
Determine the time it takes for the particle. A particle is traveling in a straight line at a constant speed of 28m/s. Suddenly, a constant force of 15.6N acts on it, bringing it to a stop in a distance of 66.8m.
