Nah, I realize that you have to be a sparky in all weather, but it's still better than returning phone calls.

I was doing a re-pipe on the west side of Colorado Springs a few years back. Changing out the old galvanized water pipe for copper. Well, this old house had only a small access door, maybe 24X24, to the crawlspace located outside. Well, I got volunteered to crawl under and start pulling down the old galvie. I lay down flat and start crawling on my belly toward the other side of the house. I get about half way across when I see green eye shine heading for me at about mach 1. Well, there was no where for me to go, so I just covered my head and waited for it to be over.
I feel something run across my back and shoot out the door. My boss yells down, "You OK?" I say yeah, what the hell was that, a cat? He says, "NO, BIG ASS RACOON!!"
I think I peed just a little bit......
You should have used a commanding voice and said, "Stop right there sir! I'm notifying the police!"
Now is a bad time to break into the electrical trade. There just isn't much work going on. I bid my butt off, and if I put any profit into the job you can bet I won't even be in the running. Very competitive. Alot of companies are buying jobs and banking on change orders to not lose their ass.
I've been hearing a lot of that, but I can't wait until it is a good time. I'm looking for another job right now, and I'll just study up on what I can find in the mean time to make myself more marketable as an apprentice.
Can some one help me understand why I got this quiz question wrong? I'll lay it all out.
10. You are told that an air conditioner has cooled a room by 500 Btu over a certain period of time. What is this amount of energy in KWh?
(a) 147 kWh
(b) 14.7 kWh
(c) 1.47 kWh
(d) 0.147 kWh
I chose (a), but the book tells me the answer is (d). I've never been good at conversions, so this was my process.
1 Btu = 1055 joules
1 J = 1 Ws
So I did 500 Btu * 1055 J = 527,500 Ws
527,500 / 3600 = 146.5
I divided by 3600 because that is how many seconds are in an hour and I need kWh instead of kWs.
EDIT: Never mind, I see that I solved for Wh, and when you convert to kWh, you just move the decimal to the left three spots. Otherwise, did I go about solving this correctly?
