Astrand of 10 lights is plugged into an outlet. how can you determine if the lights are connected in series or paralle
question 2 options:
a. unscrew one light. if the other lights stay on, it's a series circuit.
b. unplug the strand. if the first light stays on, it's a series circuit.
c..unscrew one light. if the other lights turn off, it's a series circuit.
d. cut the strand in half. if the plugged in half stays on, it's a series circuit.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

Acar of mass m goes around a banked curve of radius r with speed v. if the road is frictionless due to ice, the car can still negotiate the curve if the horizontal component of the normal force on the car from the road is equal in magnitude to 101) a) mv2/r b) mg/2. d) mg e) tan[v2/(eg)]
