This is a Physic's problem. Can anyone guide me through the following problems.?
Cute, no real problem here. Without friction, noise produced & such all kinetic energy must end up as heat. So get the kinetic energy. Maybe only trick is to use standard units. Take the km/hour into m per second. Energy = 1/2 mass * velocity^2 You have two cars, so twice the energy. Have a go. Post more if you get stuck on something, telling us where you got stuck: otherwise it's quite easy homework.
Will bad valve guides and/or bad valve seals ruin your engine?
Valve seals will only cause an oil consumption problem - if bad enough, might result in fouling a spark or two occasionally. Bad guides however can result in the valve not seating properly and will eventually cause cylinder leakage past the valve and a resulting dead cylinder. Drive it until it exhibits some driveability concerns - it won't result in any more repairs than it already needs.
Idiots guide to an oil change?
I was hoping someone could give me a VERY detailed, step by step for changing the oil on my car, a 92 Probe. I know nothing of cars (what oil to buy, what tools are needed, what to look for under the car, etc...) but because of various issues I must do it myself. If you could help, thanks a ton.
Train crew job study guide question..?
Ah yes, the lowly anglecock. But, before turning it, the brake pipe must be reduced to full service and equalized before doing so. To do so while the air is still flowing through the brake pipe can cause an undesired release of the brakes. The engineer will inform by radio or whistle signal when the brake pipe pressure has equalized. Air has many of the same properties of water, except air can be compressed. But, when flowing through the brake pipe, if one turns the anglecock, the air runs into it and sloshes backwards, like a small wave made in your bath tub. It gets to the far end, piles up and washes backwards. It only takes a 2psi increase in brake pipe pressure to release the brakes, or 1 1/2 psi to initiate a release where brake equipment on the cars has the "accelerated service release" feature. This feature allows a portion of air from the brake cylinder to flow back into the brake pipe when released with a portion of the air exhausted to atmosphere. Standard equipment vents all air from the brake cylinder to atmosphere during a release.
Building the RC car in Rage?
Yeah, I've got the same guide. Unfortunately, you can't build an RC bomb car by that time, you only get the schematics for the car during a later mission. It seems that someone posted the wrong text in that area, because that text is reused during a later mission where you return to that area and can open that door. Basically, don't worry about that door just yet, when you come back to the area, then you can get it. Edit: I went through the same thing when I hit that area, I kept thinking that perhaps I did something wrong, or missed something, but it was just an accident with the guide. Since the guides tend to be made during the development of the game, there are bound to be some changes between that point of the development to the finished game, leading to problems with the guide. Plus, the workers for the guide are only human, so there are bound to be some problems like misplace words or paragraphs in this case.
