A single-loop circuit contains a battery (nominal emf 12V & internal resistance r), a motor (resistance Rm), and a cable (resistance Rc). The circuit is part of an experiment in your lab that is not working properly because the motor is turning too slowly. You are trying to determine which component is faulty. The information for this equipment says that the battery should have no more than 0.020 Ù internal resistance, the motor no more than 0.150 Ù resistance, and the cable no more than 0.040 Ù resistance. When you close a switch to turn the motor on, you measure 11.4 V across the battery, 3.0 V across the cable, and a current of 50 A. Which component is faulty?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?
