A 150Ω resistor is connected to a coil with 30 turns and a cross sectional area of 0.02m2. A magnet is lowered as shown in the figure. The magnetic field increases from 0.01T to 0.06T in 20ms. Find the magnitude of the current going through the resistor. I = 0.1 A
I = 0.2 A
I = 0.01 A
I = 0.02 A
I = 0.001 A

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
