Since the graph is parabolic and increasing with the variable along x-axis. We know that the induced emf is directly proportional to area of the coil and the area of coil is proportional to square of the diameter of coil. So as the diameter increases the induced emf will increase parabolically. From the given options we can easily see that the correct option is option D. I,e
Diameter of the coil.

Question 6 1 pts Suppose after investigating the relationship between induced emf and diameter of the coil your group came up with a trend that was hard to differentiate between linear and quadratic. What should your group do next? Make your best guess Redo the experiment and try to reduce the uncertainty in both emf and diameter change the way the magnet is falling through the coil Redo the experiment with a different set of coils

Question 43 2 pts The rms voltage across and the rms current through a single circuit element connected to an ac generator are, respectively, Vrms = 131 volts and Ims = 37 A. The angular frequency of the generator id w = 78. It is observed that the current leads the voltage by 90°. The element that is connected to the ac generator is either a capacitor, an inductor, or a resistor (only one of the three)....

Question 35 2 pts A charged particle (with q = 1.0 x 10-2 C) that is moving through a uniform magnetic field has a velocity v = (6.0 x 105m/s) i + (4.0 x 105m/s) k when it experiences a force F due to the magnetic field. If B = (-3.0 x 10-3T)i + (4.0 x 10-3T)j + (5.0 x 10-3T)k, calculate the force, in N (in terms of unit vectors). Equation: F=qvxB OF=-(3.0 N)i - (6.0N)j...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
