Ok What do you remeber??

question 48 is wrong in a naturaly asperated motor the air enters the the cylender with the suction of the piston hence suck squwze boom blow, there is one othe question 26 that is wrong too the one where the center light bulb is seperated buy a switch all three lighs would come on unless the line from the 1 st and second and second and third light were seperated.. if the three lights were wired in series then the switc tag ends would have no effect.. help me understand why i got these two q's wrong

Current follows path of least resistance.....middle bulb doesn't lite. I missed this one too.
I had to think about it.

I missed the light, however I think it is a bit of a trick question, it would light, not as brightly depending on the resistance of the bulb, the wire etc. Of course maybe I'm overthinking it. Thank goodness my record low score is holding up.

i'm a freak about that kind of thing i have no memorative thought at all i have to figure every thing out.. all the lights will light up wire it up and try it....i have to re read the question i thought the last time i bought a suction pump it was called a suction pump not a low pressure situation. what brings the air into a cylender is SUCTION CREATED BY THE PISTON MOVING DOWN...

I got the light question right, since the current would follow the path of low resistance and bypass the middle light. But I missed the piston question. Seems to me both answers should be correct, whether you call it suction or atmospheric pressure pushing into a vaccum is describing the same phenomenon.

78%/390. Oddly only had the "Correct!" window pop up on one question. I did the test before reading down the thread, but now I don't feel so badly. :-) High school physics plus a first year physics course at Carleton U in Canada...
The pulley questions killed me.

i sir have a doctorate degree from the school of hard nocks ( ( and the southern tennesee school of faith heailing an other related tendencies)) let me enlighten you people on some things you need to know
1 to be a electritian.......whitey to whitey- blackey to blackey and stuff the reddy back in and dont let the smoke out...
2 to be a Plumber **** runs down hill paydays friday and dont lick your fingers.
3 carpenter- work real hard try your best paint and putty will do the rest
4 architect- nothin
5 interior designer----less than that
OK ILL QUIT NOW
CAN YOU TELL THE SEASON OVER AND ITS RAINING HERE

In the one with the wire bypassing the lamp, the lamp will not light up if the wire has 0 resistance, which is not possible in real life. If the wire was 1 ohm and the lamp 100 ohm, 1 percent of the current would flow through the wire.
On the vacuum question, you are creating a lower than atmospheric pressure in the cylinder, atmospheric pressure then pushes the air into the cylinder. I got 90%, guess I am ready for diesel mechanic school, and to switch on and off light-bulbs!

82% - I was doing pretty well until my A.D.D. kicked in.
Thanks for reminding me I need to work on the Tractor.
Looks like I'm in good company @ 82%

I guess so far that makes me the winner at 96%. What do I get Tom? 
The electrical question is definitely only 2 lights. All the questions were hypothetical ideal circumstances such as 0 pulley friction or 0 ohms resistance. Yes, a little tiny bit of current would probably still flow through the bulb but not enough to make it glow.
Regarding suction vs. atmospheric pressure, there is no such physical property as "suction". Yes, you are suctioning in air but that's just a term not used in physics. Technically you are reducing pressure.
As far as my own missed questions, I got the fans wrong. I knew in advance it would be a problem because it didn't stipulate whether the "direction" would be the direction of the fanblade in relation to the fan (one clockwise and one counter) or in relation to the direction of airflow.
Then I got the one about the water pipe with the A and B stacks wrong. I think I might still be correct on this one because I figured that water passing rapidly past the B stack would actually create a venturi affect and actually suck air rather than raise water. Maybe one of you can help me with this one.
