- Q: I had a little fire in my toaster oven and used my &shop size& fire extinguisher to put it out. I just pulled the trigger for a split second and it was out. Just from that the gauge has gone from &full& to &empty&. Is this just a safety measure? How can it be empty when I only used a tiny squirt?I'm going to buy another one, since it's better to have two than nonebut my question is, can you use a fire extinguisher more than once?
- there are at least 3 grades of resin, fast, medium and slow. personally i use almost only the slow, and give it overnight to fully harden. i would suggest a slower curing resin. or a slight reduction in the amount of hardner used. COLD days, use extra, HOT days, use less. some danger in using extra, as it can increase the heat of the curing process to the point of starting a fire. but if you use too little, it just wont set up properly and you'll be stuck scraping it out.
- Q: I've always wondered if someone were to create a small batch of napalm (less than or equal to an ounce) and let it burn on the side walk or concrete slab without touching anything else, would it start burning a hole into the ground, or would it just burn itself out after 8 hours+?They also say if you deprive it with oxygen, the fire will go out. Would blanketing the substance with a power based fire extinguisher stop it?PLEASE NOTE:I don't want to try thisat all. I've just always wondered. Thanks!
- I have the same problem and i got a very high endurance broom by dirt devil and it work use no vacum foam to lift any access hair dirt and odor
- Q: Ok so I know I'm a bad kid, but it's the end of my junior year and i'll feel like such a failure if I can't throw one party, my moms going out of town, i live with my dad, but she locks up the house and has a burglar alarm, I know of and unlocked door and I won't set off the alarm, you don't need to warn me, but i don't know the code, and in the living room there's this weird motion detector and when you walk past it not only does it light up, but so does the main alarm pannel it just holds a solid red light, i'm not planning to trash her house, i love and respect my mommy, i just want to throw a party, will cops come?
- Well, I doubt this really should be taken as a hydraulics problem, with nozzle losses, etc. so let's look at it as a conservation of energy problem. At the nozzle, we have a radius Rn and a water velocity Vn. From the radius we can compute the cross-sectional area, and with the area and velocity we can compute the volume of water pumped out every second. volume / time area x length / time area x velocity Taking the density of water to be 1, we can go from volume per second to mass per second and compute the the kinetic energy of the mass. In addition, taking the fire truck as the origin, the water experience a potential energy gain of mgh as it is pumped up to the nozzle. Since we are given h, have computed m, and can assume that we are on the surface of the earth and so use 9.8 m/s^2 for g, we can determine the increase in potential energy per second. Now that we have the potential and kinetic energy gains per second, we can sum them to get the total power required and go back to the fire truck. We know the radius of the hose and the volume of the water pumped per second, so we can compute the velocity of the water in the pump/hose. Then: Power force x velocity (If this isn't clear, consider Work force x distance Power work/time force x distance / time force x velocity) and we know the velocity and the power required, so we can compute the force needed. Force pressure x area and given the radius we can compute the cross-sectional area of the hose. Since we know the force, that gives us the pump pressure.
- Q: how to connect steel pipe with pvc pipe?
- Amps is the amount available sort of. Here is an over used but helpful analogy: think of it like a water hose you can have 2 hoses a fire hose, and a garden hose. if the water is comeing out at the same speed/force out of both hoses they have the same voltage 12units however because the fire hose is bigger it will have more volume 7 units, when the garden has only 4 units. As long as the water doesnt come out of the hose too fast(voltage high) you can still water delecate plants with a fire or garden hose. it just will get done faster with the fire hose(more water) As lond as your circuit board is designed to use in that range of power it will be fine odds are that it is. although it is possible to hurt if if it has too many amps but only 3 amp differnce it will make little differnce. if t was 10 or 20A difference id worry but not with 3

- Q: Its about 6ft. below it and my smoke detector has gone off a couple of times for no apparent reason
- Horizontal force on the wall, Fh rate of change of horiz. momentum of water jet (Newton 2) Initial horiz. vel, Vh (45.50 s 25) m/s Net change in Vh accounting for velocity reversal on impact .. ?Vh 2 (45.50 s 25) m/s .. .. ?Vh 82.47 m/s ? Net force (Fh) Rate of change in horiz. mom .. .. (in kg.m/s per s) Fh (m.?Vh / t) (m/t). ?Vh .. .. (m/t 16.90kg/s) Fh 16.90kg/s x 82.47m/s .. .. ?Fh 1393.70 N [ As the vertical velocity is unchanged, no vertical momentum is transferred to the call .. so Fv 0 ..and Fh is the net force on the wall ]
- Q: im making a deadmou5 head out of paper mashe, its basecly a dead mouse helmet. im still paper mashing it but if it doesnt come out as strong as i need it i may need to add something to it in order to make it stronger so it wont bend or easly fold. is there anything i could use in order to add either in the outside or the inside of the head to make it stronger/more resistant?im also planning on sanding it down to make it as smooth as possible so i can add some chrome spray paint onto it for a metallic look, would this work on paper mashe? and will the paint come off easy or does it stay on? i need spray paint that will stick permanently onto the paper mache.
- Good luck however if you are researching the overpaid government agency personnel. You really need to start with Senators and Congressional representatives. Also make sure that you include any extras. Such as the $1.5 Million that each senator and congressional representative receives as an extra expense account. Lets not forget while you are at it the fuel for the Air Force Jet that the speaker of the house uses two to three times each week to travel between the District of Columbia and her home in California. That for sure is a major waste of the taxpayers money. When you get it all figured out you can multiply it by that of 200 senators and 435 congressional representatives. This is just a start and a drop in the bucket of the congressional waste in each department of the federal and state government agencies. One of our major problems is that they refuse to correct their internal waste. Their approach is the same as that of any congressional blunders that they are responsible for. Let the taxpayers pay for it. After all section 8 of the constitution and the 16th amendment gives them the power to rob the poor to feed the rich and make the high ranking government officials even richer.
