Trucks carrying garbage to the town dump form anearly steady procession on a country road, all travelingat 19.7 m/s in the same direction. Two trucks arriveat the dump every 3 min. A bicyclist is also travelingtoward the dump, at 4.47 m/s. (a) With what frequencydo the trucks pass the cyclist? (b) What If? A hill doesnot slow down the trucks, but makes the out-of-shapecyclists speed drop to 1.56 m/s. How often do thetrucks whiz past the cyclist now?
PH 1120 - Electromagnetic Induction - Lab Report Your Name: Jordan Counsel& Section: 1F Partner’s Name: Katharine Conroy Date: 12/9/2016 1. State the value of the Earth’s magnetic field magnitude that you measured, and comment on the field orientation that you observed at your station. Bmax−bmin .06095−(−.2131) B= | 2 | = | 2 | = .137 T 2. Consider the magnetic induction situation when the magnet is rapidly inserted into a coil, held motionless, and then rapidly removed from the coil. Explain briefly the circumstances in this 3-step process that produce an induced EMF, and why their polarities are different. In the three step process we increase the EMF by inserting the magnet which is put
