Part 10: Use of Power by Lightbulbs Investigation 25. Design a simple circuit using one lightbulb and the instructions from step 1.
Set the power source at 20 V. Use the ammeter to determine the total current in
the circuit as an indication of its use of power.
IF
What happens to the bulbs' use of power if you add a second bulb with the same
resistance in series with the first?
Remove the second lightbulb, and then design a parallel circuit using two
lightbulbs that have the same resistance. How does the use of power in the
parallel circuit compare to the use of power in the simple circuit with one
bulb?

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

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.

not copied too! hope this !

h o h o hope you have a merry christmas!
