We usually ignore the kinetic energy of the moving coils of a spring, but let's try to get a reasonable approximation to this. Consider a spring of mass M, equilibrium length L0, and spring constant k. The work done to stretch or compress the spring by a distance L is , where X = L - L0.Part AConsider a spring, as described above, that has one end fixed and the other end moving with speed v. Assume that the speed of points along...

A current-carrying wire moves toward a coil A long straight wire carrying current I is moving with speed v toward a small circular coil of radius r containing N turns, which is attached to a voltmeter as shown. The long wire is in the plane of the coil. (Only a small portion of the wire is shown in the diagram.) Voltmeter N turns radius r The radius of the coil is 0.02 m, and the coil has 11 turns. At...

Please write clearly and show
your work. Thank you!
A 15-cm diameter circular wire loop spins at 250 rpm on an axis parallel to a 750-T magnetic field. Write an expression for the emf induced in this loop as a function of time. Include numbers in your expression wherever possible, and don't worry about getting the formula formatting exactly right. (Also, you may assume the initial magnetic flux to be zero if it makes this problem easier for you.)
