Review we will use a video to study faraday's law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will horizontal scale attached to the air track are in millimeters. enter the answer with two significant figures in meters per second. view available hint(s) 6.00×10-2 m/s 1. examine some of the main principles behind faraday's law. 2. apply lenz's law to determine the direction of the induced emf. 3. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. 4. use the horizontal scale provided to determine the speed of the coil 5. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field. submit previous answers all attempts used; correct answer displayed part j figure < 1 of 4 > based on the emf value measured at frame 700, what is the average magnitude of the magnetic field inside the magnet assembly? note that the loop has 10 turns; in other words, the total emf is the sum of the emfs generated in each turn. in your calculations, use 26 mv for the magnitude of the total induced emf and 0.060 m/s for the speed of the loop. express your answer in teslas and use two significant figures. view available hint(s) o aco r o p ? submit

Apositive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
