This is a physical science multiple choice questions test...…...                                            I need this done today by 7pm Please I have attached the pictures for questions 1, 5, and 10 at the bottom.  1.   Go to this website to open the Circuit Construction Simulator: http://phet.colorado.edu/en/simulation/circuit-construction-kit-dc If you can not get the simulation to run right away, please check the following: Make sure you have Java installed and updated. https://www.java.com/verify Make sure your security settings (Apple Menu > System Preferences > Security & Privacy > General tab) allows apps downloaded from anywhere. You can change this back after running the simulation if you wish. Click and drag one battery, two resistors, and seven wires from the white box to the left of the screen. Arrange the pieces into a circuit with the battery on top and the two resistors on the bottom: "LOOK AT PICTURE 1-1" (ATTACHED) Click on the battery and use the slider to change the voltage to 9.0V.  Click on the left resistor and change the value to 10 Ohms. Click on the right resistor and change the value to 20 Ohms. "LOOK AT PICTURE 1-2" (ATTACHED) Click the non-contact ammeter button in the middle of the green box. Place the crosshairs of the non-contact ammeter on the wire several places around the circuit to find the current in the wire.  What is it? " LOOK AT PICTURE 1-3" (ATTACHED) 0.15 A 0.30 A 0.45 A 0.60 A 2. Is this circuit arranged in series, in parallel, or in both formations? Series Parallel Both series and parallel 3. Based on your answer from #2, use one of the following equations to calculate the total resistance of the circuit. Resistance in series: Rtotal=R1+R2 Resistance in parallel: 1/Rtotal=1/R1+1/R2 6.67 Ohms 10 Ohms 20 Ohms 30 Ohms 4. Now, using Ohm's Law: I=V/R and the total resistance calculated in #3, what is the total current of this circuit? 0.15 A 0.30 A 0.45 A 0.60 A 5. Click the voltmeter.  A voltmeter measures the difference in the voltage between 2 places on a circuit. This is called the voltage drop. Place the contacts of the voltmeter on the circuit on either side of the battery. Note: The voltmeter tells you the voltage drop between the two points in the circuit touched by the probes.  Voltage works in a similar fashion to gravitational potential energy based on height.  Balls will only roll down board if one end is higher than the other (so it is sloped). The ball (electron) at the higher end of the board (wire) has lots of potential energy (voltage). The ball will roll down the board (electron will move through the wire) to the lower end of the board that has less gravitational potential (less voltage). You could use a ruler to measure the height difference between the high point of the board and the low point where the ball moves to. This would be the change in height or how hard the ball dropped in height. For the electron, you would use a vol.

1. This is a physical science multiple choice
questions test...…...
I need this done today by 7pm
Please I have attached the pictures for questions 1, 5, and 10 at
the bottom.
1.
Go to this website to open the Circuit Construction Simulator:
http://phet.colorado.edu/en/simulation/circuit-construction-kit-
dc
If you can not get the simulation to run right away, please check
the following:
Make sure you have Java installed and updated.
https://www.java.com/verify
Make sure your security settings (Apple Menu > System
Preferences > Security & Privacy > General tab) allows apps
downloaded from anywhere. You can change this back after
running the simulation if you wish.
Click and drag one battery, two resistors, and seven wires from
the white box to the left of the screen.
Arrange the pieces into a circuit with the battery on top and the
two resistors on the bottom:

2. "LOOK AT PICTURE 1-1" (ATTACHED)
Click on the battery and use the slider to change the voltage to
9.0V.
Click on the left resistor and change the value to 10 Ohms.
Click on the right resistor and change the value to 20 Ohms.
"LOOK AT PICTURE 1-2" (ATTACHED)
Click the non-contact ammeter button in the middle of the green
box. Place the crosshairs of the non-contact ammeter on the
wire several places around the circuit to find the current in the
wire. What is it?
" LOOK AT PICTURE 1-3" (ATTACHED)
0.15 A
0.30 A
0.45 A
0.60 A
2. Is this circuit arranged in series, in parallel, or in both
formations?
Series
Parallel
Both series and parallel

3. 3. Based on your answer from #2, use one of the following
equations to calculate the total resistance of the circuit.
Resistance in series:
Rtotal=R1+R2
Resistance in parallel:
1/Rtotal=1/R1+1/R2
6.67 Ohms
10 Ohms
20 Ohms
30 Ohms
4. Now, using Ohm's Law:
I=V/R
and the total resistance calculated in #3, what is the total
current of this circuit?
0.15 A
0.30 A
0.45 A

4. 0.60 A
5. Click the voltmeter. A voltmeter measures the difference in
the voltage between 2 places on a circuit. This is called the
voltage drop. Place the contacts of the voltmeter on the circuit
on either side of the battery.
Note:
The voltmeter tells you the voltage drop between the two points
in the circuit touched by the probes.
Voltage works in a similar fashion to gravitational potential
energy based on height. Balls will only roll down board if one
end is higher than the other (so it is sloped). The ball (electron)
at the higher end of the board (wire) has lots of potential energy
(voltage). The ball will roll down the board (electron will move
through the wire) to the lower end of the board that has less
gravitational potential (less voltage). You could use a ruler to
measure the height difference between the high point of the
board and the low point where the ball moves to. This would be
the change in height or how hard the ball dropped in height. For
the electron, you would use a voltmeter to measure how much
the voltage dropped from one point to another.

clicking on the battery and selecting “Change voltage”.

Note:
If you receive decimal points for any of your voltmeter

adding and comparing.
