An inductor (l), a resistor (r), a battery (v), and a switch are all connected in a single loop series circuit. immediately after the switch is closed,
a. the current in the circuit is l/r.
b. the current in the circuit is zero because the inductor resists the change in its current state.
c. the current in the circuit is v/r.
d. the current in the circuit is zero because the circuit contains a resistor.

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

Aracecar driver has to hold on tightly when going around a banked curve. approximately what is the centripetal force on a 2220.0 kg car going around a circle with a diameter of 190.0 meters at 25.0 m/s?
