Could somebody help explain and answer this problem for me? I'm rather confused. A fire hose ejects a stream of water at an angle of 33.1° above the horizontal. The water leaves the nozzle with a speed of 23.0 m/s. Assuming that the water behaves like a projectile, how far from a building should the fire hose be located to hit the highest possible fire?Thanks!
Try replacing the battery. Weak batteries are the most common cause of triggering smoke detectors. Good luck!
It's no small irony. Benjamen Franklin was condemned as a heretic for his invention of the Lightning Rod. Until the gunpowder exploded in a church in Lisbon during a lightning storm.
everything you listed and include running a mile before you eat breakfast. that way it kick starts your metabolism early and you'll be burning calories all day. also, lay off the alcohol. it kills your metabolism.
That's the standard signal for a low battery. You need to take the detector down and put new batteries in it probably 9 volt. Blinking red every 20 seconds and the green LED just let you know it's working and the battery isn't completely dead yet, but it still should be replaced. Note: After you replace the battery, the low battery alarm might continue to go off for a few minutes before it resets itself. Just ignore it and it will stop. Additional: Ok, that's a little different. The three loud beeps is probably still a low battery warning (the alarm going off would beep a lot more than three times), but it's warning about the backup battery. The green led indicates you have wired power. If your wired power fluctuates some, the alarm could be warning you every time the backup battery has to come on line to compensate.
