Women continue developing until about 25 sometimes this is due to hormone fluctuations & weight gain if pregnancy isn't a factor
How can connect security camera to internet?
You can purchase security cameras that will do this for you.
They have a wireless adapter which will connect to your existing WiFi system and connect to the internet via your wireless access point.
Alternatively. You can connect a camera via USB adapter for AV input, to your computer. The computer must be online. Sign up to a webcam host site and link to your camera.
What is RMS value of an AC Sinusoidal Waveform and the power they carry?
Hi,
RMS is voltage X .707 and the power is voltage X current.
Hope that helps,

a contactor is generally looks like a small box connected to an electric circuit. it is what controls electricity flow to a motor. in the middle is normally a way to push in the contactor to manually check to see if either the motor works or if you have electricity.
Where should you put rear speakers for surround sound?
Ideally you want them behind you with one to the left of you and the other to the right. You can do a search on the net for surround sound speaker layout and you'll get a couple of examples as to where to put them. If you have satellite speakers for the surround (these would be the smaller speakers) than you will want them mounted on the wall (with speaker mounts due to the positioning of the speakers) so that they are pointed at the location you will be watching television. This goes for all the speakers. The receiver should have a set up feature that will either have you inputing information as to the location of every speaker (distance in feet the speaker is from where you will be sitting) or if you have a higher end model than you might just have to plug in the mic (will come with the receiver) and put it where you will be sitting and let the receiver run through a series of sound checks to figure out the best settings based on your positioning.
Any logical function can be implemented with only NOR gates?
Yes.
_____
A----|_____NOR------Q
This is an inverter. A NOR gate is an OR gate with an inverter on the end, so adding the above configuration after another NOR gate would give you an OR gate.
__
A----|__NOR---\
__ NOR------Q
B----|__NOR---/
This is an AND gate. By adding the inverter, you can get a NAND gate.
A____
|__
_|__NOR----------------\
| | \
| |___ NOR----Q
B __| |___NOR-----\ /
|_____ NOR --/
|_____NOR-----/
By combining an AND gate, an OR gate, and a NAND gate, and canceling out a couple of inverters, you get this operator, which is a XOR gate.

How do you turn off the hourly beep on an Aspen p-jadae watch?
I'm not sure how closely it resembles my Aspen P-JADDC but please see below.
Button Legend:
1 - Illuminate (top left)
2 - Mode (bottom left)
3 - Start / Stop (top right)
4 - Reset (bottom right)
To turn hourly beep / chime on and off:
While holding #4, press #2. You should see the days of the week at the top of the display either show up or disappear.
I hope this helps...
An LDR (light-dependent resitor) is a particular type of semiconductor (A material with a conduction rating in between that of a conductor and an insulator i.e. electricity flows through a semiconductor slower than through a conductor, but quicker than through an insulator).
Consider an atom as made up of just a nucleus with bound electrons. These electrons require varying amounts of energy to 'escape' from the atom. The semiconductor, as all known matter, is made up of atoms.
Light can currently be explained as being made up of packets of waves called photons where the frequency of these waves determines how much energy they are associated with (Energy = h * frequency: where h is a constant).
Therefore, if light associated with enough energy stikes the semiconductor, then the electrons requiring the equivalent energy to break the bonds will escape.
Electricity is concerned with a flow of electrons, therefore electrons escaping means there is an increase in electrical current.
This increased electrical current is equivalent to a drop in resitance and thus fluctuation in particular frequencies of light affects the resistance of the semiconductor.

Do the clocks get turned back or forwards at the end of Daylight Saving Time?
Clocks get turned BACK one hour - an easy way to remember this operation is "Spring Forward, Fall Back."
A dead zone in an read that is between cell phone towers. It is usually located where there are no overlapping towers. Areas between tall buildings and mountains can also be dead zones.
Is it worth fixing an iron that keeps blowing fuses in your house?
It may not be the iron that is the problem. It might be what else is on that same circuit that you plug the iron into. To check the problem out, unscrew the fuse and see what else on the circuit shuts off. If there are any loads that can be unplugged do so. Then try the iron again and see if the fuse blows. Try the iron in another plug from a different circuit, if a different fuse blows then its time to get a new iron.
