Q:Do you think working a job selling vacuum cleaners would be a sucky job?

yes. I am the worst salesperson ever. I am too empathic and honest.

Q:Are you scared of vacuum cleaners too?

No. The cats and dogs are afraid of the vacuum.

Q:If One doesn't care about phase-frequency or voltage and need a high speed generator can current be fed to the rotor so that these motors can be used as a generator?One more question:What voltage is needed for the rotor? Say for example the120 volts single phase motor's normal running speed is 10,000, what voltage needs to be fed to the rotor so that if one is turning the motor at this speed it would generate around 120 Volts. I know there is a lot of problem with this set up but since its being converted to DC and used in a hydrogen production system, Voltage or frequency isn't a big issue.

Plug-in drills and vacuum cleaners have usually been universal motors, essentially the same thing as series connected DC motors. I don't believe they can be used as generators without changing the internal connections. The Dyson vacuums apparently use permanent magnet motors as do battery powered drills. Those motors would probably make good generators, but you would need to eliminate the electronic control and connect directly to the motor coils. Any motor that can be used as a generator would generate the rated voltage at the rated speed for which it was designed as a motor.

Q:must be taken in order to be 90% confident that the margin of error will not exceed 50 hours? Please show work

The 90% confidence z-value from the normal probability table is 1.645 Sample size n = [ (1.645) SD /error] ^2 n = {(1.645)(400)/50]^2 n =173.18 ≈ 174

Q:have headlights?

I don't know about the vacuum cleaners but the lights on the mower are so you can get home from the bar safely!

Q:1. Vacuum Cleaners2. Straws3. American Idol4. or ????

or Ryan Seacrest?

Q:i tend to want a cannister because it easier to get underneath beds, tables, sofa......gimme brands and models if you can,,,XOXOXO

I'd okorder

Q:ok i was going to vacuum both the carpet and hardwood but i don't know how to change the sliding thing on the bottom of the vacuum and where to put it should i just put it on hard? making sure because i dont want to ruin the hardwood Thanks!!!!!

most vacuums will scratch up hard wood floors so it is better to dust mop it.

Q:I have 2 vacuum cleaners, both need new electrical cords! How do I replace them?

I ran over my cord one time and had to take my vacuum cleaner to a repair shop to have a new cord put on. It was cheap. Maybe it was about 12 or 15 dollars.

Q:Why are vacuums so loud?

I find them not so loud when I'm not hungover lol
