Consider a rectangular metal loop of length of 0.15m and width of 0.08m. This loop is located at the edge of a constant 1.2T magnetic field directed out of the page. The loop is then pulled out of the field with a force F to the right, which produces a constant speed of 8.0m/s.
Determine the emf induced in the wire on the left side of the loop.
Determine for how long a current will flow in this loop.
Evaluate (a) the acceleration of each object, (b) the tension in the string, and (c) the coefficient of kinetic friction between m2 and the incline.
Illustrate what should be the other mass so that the displacement of either mass during the first second following release is 0.34 m? Assume a massless, frictionless pulley and a massless string.
A uniform electric field of magnitude 395 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 3.00 cm. (a) What is the work done by the field on the electron? J (b) What is the change in..
A uniform rod of mass 2.65×10?2kg and length 0.450m rotates in a horizontal plane about a fixed axis through its center, find the angular speed of the rod after the rings leave it
what is the velocity of plane with respect to the ground. A nonconducting sphere has radius R = 2.53 cm and uniformly distributed charge q = +6.00 fC. Take an electric potential at the sphere's center to be V0 = 0.
What is the difference between mass and weight? On earth, what is the weight of a 1 kg mass?
A moving particle encounters an external electric field that decreases its kinetic energy from 9800 eV to 8350 eV as the particle moves from position A to position B. The electric potential at A is -43.0 V, and that at B is +23.0 V. Determine the ..
A long solenoid has 80 turns/cm and carries current i. An electron moves within the solenoid in the circle of radius 3.10 cm perpendicular to the solenoid axis. The speed of an electron is 0.0330c (c = speed of light). Find current i.
You hang the rod vertically and attach a 74 kg mass to the bottom, and you observe that the bar becomes 1.74 cm longer. From these measurements, it is possible to conclude the stiffness of one interatomic bond in titanium.
The K-shell ionization energy of copper is 8979 eV. The L-shell ionization energy is 951 eV. Determine the wavelength of the Kα emission line of copper. What should be the minimum voltage be on an x-ray tube with a copper target in order to see the K..
A computer is reading data from a rotating CD-ROM. At a point that is 0.037 m from the center of the disc, the centripetal acceleration is 120 m/s2. What is the centripetal acceleration at a point that is 0.054 m from the center of the disc
Using kinematic equations prove that if two balls are released simultaneously from a table, one with zero velocity and other with horizontal velocity, they will both reach ground at the same time.
