Explain what would happen if you use a wooden toothpick to close a circuit 1.Electric current will flow through the circuit because the toothpick is a conductor.
2.Electric current will flow through the circuit because the toothpick is an insulator.
3.Electric current will not flow through the circuit because the toothpick is a conductor.
4.Electric current will not flow through the circuit because the toothpick is an insulator.

An object has a weight of 500 on earth what is the mass of this object

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
