Physics 1101 Prelab

Physics 1101 Experiment 3 Pre-Laboratory Assignment Name and PSID TA You must show and explain all work neatly to receive credit. Please show each step for calculations, YOU MUST TURN IN THIS SHEET to have your assignment graded. 1. Assume the radii used for the experiment are 13.00 cm and 21.00 cm. Calculate the value of Ax for each of these radii. Remember that the circumference of the circle is divided into 36 equal parts. (4 pts) 2. NOTE: The following question must be solved using guly symbolic algebra. (a) During the experiment, if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was Vo initially? (b) Now, if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was Vo initially? (c) If, during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially Fg? (12 pts) 3. Compute the Moon's centripetal acceleration in its orbit around the Earth. Recall that the Moon orbits the Earth every 28.0 days and about 240000 miles from the Earth. What force causes this acceleration? Be sure to convert to SI units. Report the answer using symbolic algebra first and then report numerical value. (4 pts) Page 1 of 1
