Please Help Its Due Now! An electromagnet is a coil of wire with a current running through it. This creates an electromagnetic field. An additional magnet and its poles interact with the electromagnet, causing an electromagnetic motor to turn. What are some ways you could make an electromagnetic motor stronger, and how could you apply these principles to everyday life? In three to five sentences, explain this phenomenon in real life and hypothesize about how you could strengthen it.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

The temperature in gavin's oven is a sinusoidal function of time. gavin sets his oven so that it has a maximum temperature of 280°f and a minimum temperature of 240°. once the temperature hits 280°, it takes 20 minutes before it is 280° again. gavin's cake needs to be in the oven for 30 minutes at temperatures at or above 270°. he puts the cake into the oven when it is at 260° and rising. how long will gavin need to leave the cake in the oven? (round your answer to the nearest minute.)
