Can someone help please it keeps coming up incorrect:

Part 1)

Consider a transformer as pictured below. The transformer consists of two coils wound around a common ferromagnetic iron core. The input end of the transformer has N1 = 39 turns, while the output end of the transformer has N2 = 20] turns. Ferromagnetic Iron Core Voltage Out: V2 Voltage In: V1 Current In: |1 Current Out: I2 I' I' l' l' I' l' I' l' I' t' I' I' I vA'A'A'A'A'A'A'A'A'A'A'A" Is this a step up or step down transformer? (No answer given] An amount of data was collected for this transformer for various input powers. The input voltage Vi input current I1and output currentlg are measured and presented in the table below. Complete the table by calculating the input power P1 [In WA1TS], the output voltage V2 and the output power Pg. it is a good idea to hit the 'check' button as you go to make sure you aren't making a mistake :l. (Here, don't worry about significantgures'. 3 Sig Figs is a good idea to keep to).

This can be rearranged to give: Edit 2 thI'B. Remember that the EMF. 8, is the voltage. In the questions below it is useful to think about integrating this expression over the relevant time periods. 1. According to Faraday's law, what is the magnitude of the total area under ONE SIDE of the graph? Herer one side means the part of the cu rue that is either the magnet entering or leaving [as a hint: they both should be the samel). {To get the '1' symbol in the box. type Phi} 2. Over the course of the magnet's fall, what will be the TOTAL change in flux through the coils? Herer consider both the magnitude and the sign of the area under both sides of the graph. 3. Which of the following variables is the size of the peak (i.e. the highest magnitude voltage on the graph) proportional to? Velocity Number of Turns l_. Orientation of Magnet 4. In these experimental results, the second peak has a larger magnitude than the rst peak - why? The magnet exits the coil faster than it enteredr due to gravity
