Revolution Records will build a new recording studio on a vacant lot next to the operations center. The land was purchased five years ago for $450,000. Today the value of the land has appreciated to $780,000. Revolutionary Records did not consider the value of the land (it had already spent the money to acquire the land long before this project was considered). The NPV of the recording studio was $600,000. Should Revolution Records consider the land in the NPV analysis? If yes, what value should be used, $450,000 or $780,000?

Solution: For this situation, the version of the torque formula is simplest to apply: τ1 = r1F1 (CCW direction) τ2 = r2(F2cos30°) (CW direction) Combine into a net torque: τnet = r1F1 - r2(F2cos30°) Calculating Torque In the diagram, two forces act on a disk: F1 at radius r1 and F2 at radius r2. The net torque around an origin at the center of the disk is τnet. Treat CCW as the positive direction. F1 = 22.0N r1 = 3.24m F2 = 15.0N r2 = 1.64m τ = N.m

Consider an electromagnet, shown by the field lines in the attached figure, capable of producing a maximum magnetic field of (1.50 + A) T (teslas). A circular loop with N = (D + 15) turns of wire with a diameter of D = (4.50 + B)cm (centimeters) is placed between the poles of the electromagnet. What is the induced EMF in the loop, if the electromagnet is turned on to full strength in (1.20 + C)ms (milliseconds)? Assume the loop is perpendicular to the magnetic field. Calculate the answer in volts (V) and rounded to two significant figures. Do NOT post your work or your values for A, B, and C, just your answer. Your answer is either marked with 2 points, if it is correct or you are welcome to submit a second attempt by clicking on the REPLY TO DISCUSSION button at the top of the CAT Forum. If it is incorrect a second time, the answer will be provided.
