An inductor in an electric circuit is essentially a coil of wire in which the voltage is affected by a changing current. Bydefinition, the voltage caused by the changing current is given by VL=L(di/dt), where L is the inductance (in H). If VL=9.0−0.4t for a 3.0-H inductor, find the current in the circuit after 20 s if the initial current was zero.

After 20 s, the current is A.

Two friends went to get ice cream sundaes. they each chose a flavor of ice cream from a list of vanilla and chocolate and toppings from a list of hot fudge, strawberries, sprinkles, peanuts, and whipped cream. use the sets below describing their choices and find b'. let a = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream} let b = {vanilla, hot fudge, sprinkles, whipped cream} let c = {chocolate, hot fudge, peanuts, whipped cream} {vanilla, hot fudge, sprinkles, whipped cream} {chocolate, strawberries, peanuts} {chocolate, strawberries} {vanilla, strawberries, peanuts}
