m = 0.190 g
to threads of length L as shown in the figure.
There are two strings in the figure. The top of each string is connected to the ceiling, and both strings are connected at the same point. The bottom of each string is connected to a spherical mass labeled m. Both strings have length Land hang at an angle of θto the vertical, with the two strings on opposite sides of the vertical.

- You are working in a factory that produces long bars of copper with a square cross section. In one section of the production process, the bars must slide down a plane inclined at an angle θ = 21.0° to the horizontal. It has been found that the bars travel with too high a speed and become dented or bent when they arrive at the bottom of the plane and must be discarded. In order to prevent this waste, you devise a way to deliver the bars at the bottom of the plane at a lower speed. You replace the inclined plane with a pair of parallel metal rails, shown, separated by a distance ℓ = 2.00 m. The smooth bars of mass m = 1.00 kg will slide down the smooth rails, with the length of the bar always perpendicular to the rails. The rails are immersed in a magnetic field of magnitude B, and a resistor of resistance R = 1.00 Ω is connected between the upper ends of the rails. Determine the magnetic field necessary in your device so that the bars will arrive at the bottom of the plane with a…arrow_forwardYou are working for a company that manufactures motors and generators. At the end of your first day of work, your supervisor explains to you that you will be assigned to a team that is designing a new homopolar generator. You have no idea what that is, but agree wholeheartedly to the assignment. At home that evening, you go online to learn about the homopolar generator and find the following. The homopolar generator, also called the Faraday disk, is a low-voltage, high-current electric generator. It consists of a rotating conducting disk with one stationary brush (a sliding electrical contact) at its axle and another at a point on its circumference as shown in the figure below. B A uniform magnetic field is applied perpendicular to the plane of the disk. When superconducting coils are used to produce a large magnetic field, a homopolar generator can have a power output of several megawatts. Such a generator is useful, for example, in purifying metals by electrolysis. If a voltage is…arrow_forwardYou are working as an expert witness in a civil case. You have been hired by the attorney for a company that manufactures compasses. The company is being sued by a novice hiker who used one of the company’s top-level compasses. The hiker claims that the compass was defective, sending him off in a different direction from his desired direction. After taking off in the erroneous direction, he dropped and lost his compass so that he could not take subsequent measurements. As a result, he became lost for days, with the subsequent ill effects on his health and lost wages from missed days at work. The hiker has provided the exact location at which he took the erroneous compass reading. You take a trip to this location and look around. You notice that there is an electric power transmission line directly above your location, running in a north–south direction. Using trigonometry, you determine that the power line is a vertical distance of 6.65 m above the ground. Upon returning to your…arrow_forward
