Does polarity reverse in both wire in an ac circuit?
If you use 'polarity' in the sense of electric charge, no, it does not. Voltage is simply another word for potential difference and potential difference doesn't have an electric charge. Potential, on the other hand does, but its charge polarity depends on from where it is being measured. If you use 'polarity' in the sense of direction, then, yes, it does. You can allocate direction to a voltage.
How does water polarity affect it being a solvent?
It dissolves all polar and ionic substances .
In an closed circuit will the lights be on or off?
Lights are on in closed circuit. It means that is a current flowing when circuit is being closed.
What is used to measure the intensity of current flow in a circuit or branch in a circuit and is wired in series with the circuit being evaluated?
An Amp Meter
How do you de-energize a circuit?
To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.
When is it important to make sure to match the polarity of the meter leads to the polarity of the circuit being tested?
This is important when meter cannot display negative values, e.g. it is analogous meter with scale. Most digital meters can display negative values. P.S. I am amateur in elecrtonics.
How does voltmeter loading affect a circuit being tested?
Meters are designed to have a high input impedance so that the circuit being tested is minimally affected.
When resistance and continuity test are made on electronic circuit components the circuit being tested should be?
Open
What is the important part of an experiment that is not being tested and is used for comparison?
The control group
What is the most important thing consider when designing an experiment?
The Hypothesis being tested

What is a factor being tested in a experiment?
The factor being tested is the dependent variable.
What factor Is being tested in a controlled experiment?
The factor being tested is the dependent variable.
What is the importance of control set up in an experiment?
So you can make sure the results you gain are only due to the independent variable and not a variable not being tested.
How do you find out what systems are damaged after connecting the battery in reverse on a 1989 Ford F-150?
You can count on the alternator diodes being fried. But you might be able to have it tested. After that, much of the OTHER stuff has protection. Unfortunately, polarity protection is difficult if not impossible with an alternator.
Why are cows being tested in California?
Cows are being tested because Scientists need it to test it for MILK
What percentage of animals get side effects after being tested on?
Well that depends on what they are being tested on and what animals are you speaking of.
