Apower source supplies a prescribed voltage and is used to power a light bulb if another light bulb is connected in series to the first how would it affect the current in the power source? .

It would decrease.

Explanation:

From Ohm's law:

I = V/R

I = current

V = voltage

R = Resistance

The power source supplies a fixed voltage (V). Let the resistance of each light bulb be R.

When a light bulb is connected across voltage V, current I = V/R flows in the circuit.

When another bulb is added in series, the net resistance increases:

R' = R + R = 2 R

Because of increase in resistance, the current drawn in circuit decreases.

⇒ I' = V/2 R = I/2

write a paragraph or story to explain the transformation between potential and kinetic energy as shown in your picture or model.  

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))
