Science & Mathematics - 6 December 2006

Ok, I'm lost on this section. This is an unassigned HW question I think would help me to figure out if I could see how to do this the question is to find a general form for x'-y^2=2x or dx/dy - y² = 2x and then to show it is really the answer.
I can't figure this out, any help?

ok my teacher wants us to figure out how a boy a hundred years ago got the solution to this problem in few seconds
the problem goes. whatr is the solution of all the NATURAL numbers added together. thas 1+2+3+4+5+6+7+8+9+10+11+12+13+14+15..........+100
(you add all the numbers from 1 to 100 together, and get the solution in a fast way)
ps. if you can give the the solution to the addition

Could you also explain what matter is in laymen terms or in other words dumb it down or say it in a way I can understand.

the correct Lewis structure for SOCl2?

It breaks the octet rule.

At first guess, from looking at photos of counter-rotation blades, I would imagine that there is a gear system which changes the rotation of one set of blades (on a common shaft) in the opposite direction to the other set of blades.

Does anyone have a clear way of explaining this to me? Or better yet, does anyone have a diagram of the internal workings of the counter-rotation process?

It starts from rest and travels 40 m in 3 seconds. I know accel = v-vo/time. But I don't get how to get that stuff. So how would I find accel and velocity and vo from this info

A lumberjack (mass = 98 kg) is standing at rest on one end of a floating log (mass = 280 kg) that is also at rest. The lumberjack runs to the other end of the log, attaining a velocity of +2.8 m/s relative to the shore, and then hops onto an identical floating log that is initially at rest. Neglect any friction and resistance between the logs and the water.
(a) What is the velocity of the first log just before the lumberjack jumps off? (Indicate the direction of the velocity by the sign of your answers.)
in m/s
(b) Determine the velocity of the second log if the lumberjack comes to rest on it.
in m/s
