What does the snooze button do?

well lets put it this way, on a day that you need to go somewhere early in the morning and CANT be late, set your alarm 30 min before you need to leave, then when the alarm goes off, hit snooze over and over and over again, repeating the process about 10 times or so, then tell me what your boss or girlfirend, etc., thinks after you get there

In what form geothermal energy is stored?

Geothermal energy is energy stored in the form of heat beneath the surface of the solid earth.

Do you think online games should be banned?

Nope. Its the only way that some people can socialize with others. If they were banned, I would have nothing to live for, no friends no games no nothing. No life! Plus, you don't even HAVE to play them.

Why is magnesium not used for making car boodies?

Because boys lick girls boodies and have sex with them!I want to have sex with all of the boys in the world!

What is A microwave leak detector?

A portable handheld radio receiver operating in the microwave band, that when it detects microwave RF above a certain strength it gives some form of warning signal. This warning may be audible, visual, or be shown on the face of a meter.

Can you recover Purged Messages from Outlook Express?

To recover outlook express data try to use following programming method below

What is Proximity Searching?

Proximity searching is a way to define what results you see. It lets you use a specific key word to then narrow down your results.

How do you use the video feature on a Canon Powershot A540?

Step 1: Select the shooting mode to video. (If U can't do this plz see the Quick/full reference guide.)

Step2: Full press the shutter button to start recording

step3: Full press the sutter button to stop recording.

Regarding how much (time) of video you can record at a one go plz refer to the camera manual. This depends upon your available amount of space. There some restrictions when you shoot in video mode. Plz refer to the guides to understand the restrictions.

Is it possible to solder aluminum?

Short answer YES it is possible.
Long answer below:
Aluminum soldering can be simple but has a number of critical areas that need tight process control. Tenacious aluminum oxide makes most attempts to solder using conventional means difficult. In addition, care must be taken regarding alloy choice due to potential galvanic corrosion consequences because of aluminum’s dissimilarity with many conventional solders. The varieties of aluminum alloys, gauges, and tempers often display widely varying soldering results, and how aluminum accepts or rejects heat during soldering must be carefully studied for each individual job.
Soldering can be done with either soft solders (Sn-based, lower temperature) or hard solders (Zn-based, higher temperature) and with appropriate fluxes to fit processing temperature ranges. By definition, soldering is a low-temperature joining process. Therefore, less distortion of the aluminum component is expected by soldering than by brazing, welding, or other fusion joining processes. Soldering temperatures of 225 to 490°C are well below the 661°C aluminum melting temperature, although 490°C is above the annealing point. Stresses in the aluminum from shearing, drawing, and heat treating are changed by the localized heating encountered during soldering, and distortion may result. Preheating, noncontinuous joints, and careful selection of joint geometry becomes critical.
Various aluminum alloys have different solderability: 1xxx, 2xxx, 3xxx, 4xxx, and 7xxx are easier to solder than the 6xxx series alloys. Due to their magnesium content, 5xxx series alloys are the most difficult to solder.
Dangers of Overheating
Due to its low melting temperature, aluminum may be annealed or tempered at temperatures as low as 325–350°C in a relatively short time. This suggests that any joining process approaching these temperatures for more than a brief interval may begin to alter the properties of the base metals being joined. Overheating may result in stress relieving, sagging or warping panels, altering hardness, temper, surface condition, re-alloying of the base metal in the immediate joint area, hot cracking, or even a dreaded meltdown.

There are aluminum solders that do not require fluxes. Instead of flux, they require the use of a stainless steel brush to remove the aluminum oxide from the surfaces to be soldered. The melting point is 388°C / 732°F. One such product is Durafix. You can find the videos of it in use at Youtube.com

Is it true that putting cassette tapes in the freezer revitalises them?

No, putting cassette tapes in the freezer will not revitalize them. This will damage the tapes. However, putting batteries into the freezer will revitalize the battery charge.

Disadvantages of electronic media?

A disadvantage of electronic media is that even though our ways of communication have improved greatly, we've lost a great deal of depth in our communication. We are losing person to person relationships with each other and self-understanding that came from normal communication.

What are the characteristics of electronic media?

Characteristics of electronic media include an invisible audience, invisible boundaries, speed, mass audiences, and false identities. Electronic media brings mass audiences together in the same place, overcoming physical and emotional boundaries.

Contribution of technology to man development?

Without technology, humans would not have evolved into what we've become. To primitive man, fire was the technology that was most important. As humans developed and learned to use tools and farm, a larger population was able to be supported. As time moved on, technologies improved,and an even larger population could be sustained. Improving on technologies as humans have evolved is the key to survival of the species.
