Concept explainers

A machine is a device that accepts energy in some available form and utilizes it to do a type of work. Energy, work, or power has to be transferred from one mechanical part to another to run a machine. While the transfer of energy between two machine par…

Kinetic Energy and Work-Energy Theorem

In physics, work is the product of the net force in direction of the displacement and the magnitude of this displacement or it can also be defined as the energy transfer of an object when it is moved for a distance due to the forces acting on it in the d…

Chapter 7, Problem 37P

GO Figure 7-40 gives the acceleration of a 2.00 kg particle as an applied force F → a moves it from restalong an xaxis from x= 0 to x = 9.0 m. The scale of the figure’s vertical axis is set by a_s = 6.0 m/s². How much work has the force done on the particle when the particle reaches (a) x= 4.0 m, (b) x= 7.0 m, and (c) x = 9.0 m? What is the particle’s speed and direction of travel when it reaches (d) x= 4.0 m, (e) x = 7.0 m, and (f) x= 9.0 m?

1. A large power cable carries I = 200 A in a straight line East-West for L = 100 m to a device and returns the same current to the power source in the opposite direction. The return path is also straight and runs parallel to the first path directly above it. Up > North ○ South West- East Device 100 m Current Source Down The cable is made of copper with resistivity po = 17.2×10 Qm and mass density pcu = 8960 kg/m³. The cable has a diameter of d = 8.00 cm. a) What force (magnitude and direction) is exerted on the outgoing (+) cable by the magnetic field of the earth? Use a value of B = 40.0 μT for the earth's field, and assume it points, straight north. [1 point] b) Is there a force between the two cables, and is it attractive or repulsive? Briefly explain your answer. [0.5 points] c) How far apart should the two cables be kept so that the force between them is less than 1.0 N? [1 point] d) Suppose the cables are set apart at the distance you got in c). How much torque is exerted on the…
