In a region where there is a vertical magnetic field of 1.96 times 10^-2 T, a ring of radius 1.02 cm is flipped in the air as one would flip a coin, so that it begins rotating about a horizontal axis at the rate of 54.0 rev/s. (a) Find the maximum instantaneous emf induced in the ring if the ring has a resistance of 1.10 times 10^-4 Ohm. Find the maximum current if the ring has a resistance of 1.10 times 10^-4 Ohm.
(b) What effect does the magnetic field have on the rate of rotation?

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
