The principle of equivalence states that all experiments done in a lab in a uniform gravitational field cannot be distinguished from those done in a lab that is not in a gravitational field but is uniformly accelerating. For the latter case, consider what happens to a laser beam at some height shot perfectly horizontally to the floor, across the accelerating lab. (View this from a nonaccelerating frame outside the lab.) Relative to the height of the laser, where will the laser beam hit the far wall? What does this say about the effect of a gravitational field on light? Does the fact that light has no mass make any difference to the argument?

LO10.3You are a management accountant for Time Treasures Company, whose company has recently signed an outsourcing agreement with Spotless, Inc., a janitorial service company. Spotless will provide all of Time Treasuresâ janitorial services, including sweeping floors, hauling trash, washing windows, stocking restrooms, and performing minor repairs. Time Treasures will be billed at an hourly rate based on the type of service performed. The work of common laborers (sweeping, hauling trash) is to be billed at $8 per hour. More skilled (repairs) and more dangerous work (washing outside windows on the 23rdfloor) are to be billed at $18 per hour. Supervisory time is to be billed at $20 per hour. Spotless will submit monthly invoices, which will show the number and types of hours for which Time Treasures is being charged. The outsourcing contract is simple and straightforward. What are some of the internal control problems you foresee as a result of outsourcing the janitorial service with this contract?Explain recommendations to control risk that would you suggest after reviewing the contract.

Distances between points in a plane do not change when a coordinate system is rotated. In other words, the magnitude of a vector is _invariant_ under rotations of the coordinate system. Suppose a coordinate system S is rotated about its origin by angle \varphi to become a new coordinate system \text{S}^{\prime} , as shown in the following figure. A point in a plane has coordinates ( _x_ , _y_ ) in S and coordinates \left( {x^{\prime},y^{\prime}} \right) in \text{S}^{\prime} . (a) Show that, during the transformation of rotation, the coordinates in \text{S}^{\prime} are expressed in terms of the coordinates in S by the following relations: \left\\{ \begin{matrix} {x^{\prime} = x\ \text{cos}\ \varphi + y\ \text{sin}\ \varphi} \\\ {y^{\prime} = \text{−}x\ \text{sin}\ \varphi + y\ \text{cos}\ \varphi} \end{matrix} \right.. (b) Show that the distance of point _P_ to the origin is invariant under rotations of the coordinate system. Here, you have to show that \sqrt{x^{2} + y^{2}} = \sqrt{{x^{\prime}}^{2} + {y^{\prime}}^{2}}. (c) Show that the distance between points _P_ and _Q_ is invariant under rotations of the coordinate system. Here, you have to show that \sqrt{{(x_{P} - x_{Q})}^{2} + {(y_{P} - y_{Q})}^{2}} = \sqrt{{({x^{\prime}}_{P} - {x^{\prime}}_{Q})}^{2} + {({y^{\prime}}_{P} - {y^{\prime}}_{Q})}^{2}}.

The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer dives from it, starting just before the swimmer steps on the board until just after his feet leave it.

A solid cylindrical conductor of radius _a_ is surrounded by a concentric cylindrical shell of inner radius _b_ . The solid cylinder and the shell carry charges + _Q_ and – _Q_ , respectively. Assuming that the length _L_ of both conductors is much greater than _a_ or _b_ , determine the electric field as a function of _r_ , the distance from the common central axis of the cylinders, for (a) r < a; (b) a < r < b; and (c) r > b.

Critical Thinking A microscope has the objective lens 6.00 mm from an object. The focal length of the objective lens is 4.00 mm. The eyepiece has a focal length of 50.0 mm and is initially 25.0 mm from the objective lens. (a) The objective lens is moved to 5.00 mm from the objective, effectively lengthening the microscope. How does this affect the magnification of the microscope? (b) Does moving the objective increase closer to the object increase or decrease the magnification, or does it remain the same? (c) Do you think moving the objective from 6 mm to 7 mm from the object will increase or decrease the magnification of the microscope, or will it likely remain the same? (d) What indicates whether the image is upright or inverted?
