Astrand of 10 lights is plugged into an outlet. how can you determine if the lights are connected in series or parallel?
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.

measure their densities same density, same sub

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
