1) Draw a circuit diagram containing a battery with 2 dry cells in series, one pathway with an open switch and a lamp. Show the direction of electron flow. 2)Draw a circuit diagram containing a battery with 2 dry cells, one pathway with a closed switch and a lamp.

3)Draw a circuit diagram containing a battery with 3 cells in series, two pathways with a lamp on each path. Add a switch that would control the lamps on both paths.

4) Draw a circuit diagram containing a battery with 4 cells in series, three pathways and a lamp on each path. Add switches to control each of the lamps and a fourth switch to control all of the lamps.

less than one you can't create energy

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
