Suppose the first coil of wire illustrated in the simulation is wound around the iron core 6 times. suppose the second coil is wound around the core n2 = 12 times. shortly after the switch has been closed, the flux through the second coil of wire changes from 1.9 wb per turn to 2.4 wb in each turn of wire over a time interval of 0.2 s. find the magnitude of the emf induced in the coil.

Sundar used linear combination to solve the system of equations shown. he did so by multiplying the first equation by 5 and the second equation by another number to eliminate the y-terms. what number did sundar multiply the second equation by? 2x+9y=41 3x+5y=36

Mackenzie needs to determine whether the rectangles are proportional. which process could she use? check all that apply.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
