Diagram 1 Diagram 2 1.What components do the letters A, B and C represent?

A Wires B Battery C..Lights.

2.What is the name given to the way the bulbs are arranged in Diagram 1?

Series circuit

3.What is the name given to the way the bulbs are arranged in Diagram 2?

Parallel circuit
4.In a series circuit, like in Diagram 1, how is the brightness of the first bulb affected when the second bulb is connected? Explain why this happens?





5.In a parallel circuit, like in Diagram 2, how is the brightness of the first bulb affected when the second bulb is connected? Explain why this happens?



6.Give one example of where we might find a series circuit in everyday life.



7.Give one example of where we might find a parallel circuit in everyday life.



8.Explain one advantage of using a parallel circuit rather than a series circuit.



9.Dan and Tom build a circuit like the one shown below.

(a)Name the component labelled X

(b)What are Dan and Tom using the component labelled X to measure?

(c)Dan says, “Ammeter 1 will show a lower reading than Ammeter 2 because the bulbs in the circuit use up the current.”
Tom says, “Ammeter 1 will show the same reading as Ammeter 2 because current is not used up.”
Who is right?

(d)If Ammeter 1 has a reading of 1.5A, what reading will Ammeter 2 show? A

10. (a) The circuit above contains 2 cells. Describe what would happen to the bulbs if Dan and Tom added another cell.



(b) Describe how the reading on the reading on the ammeters would change if another cell was added to the circuit.

answer would be d.) i hope this

explanation:

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

so here is the information for current research:

-nrel's geothermal analysts, scientists, and engineers perform a full range of research from developing advanced methods of locating and accessing geothermal resources to exploring innovative technologies to extract and produce clean energy from the heat of the earth

and here is the information for the technology of geothermal energy:

-it's clean and sustainable

-resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma

-almost everywhere, the shallow ground or upper 10 feet of the earth's surface maintains a nearly constant temperature between 50° and 60°f (10° and 16°c)

-geothermal heat pumps can tap into this resource to heat and cool buildings

-a geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building

-in the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system

-in the summer, the process is reversed, and the heat pump moves heat from the indoor air into the heat exchanger

-the heat removed from the indoor air during the summer can also be used to provide a free source of hot water

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
