Here is my concern,
In my physics class I learned that a dipole moment always goes from the - charge to the + charge. But as I was reading my Organic Chemistry book, it says that the dipole goes from + to -! how can this be?
P = Qd
Does anyone know about this?

2nd problem
ok the hyp that you got is good.
a^2 + b^2 = c^2
a= 16
b = .182
c = 16.001 using the formula. Good you got until this point.
2nd step= get the angle theta. (see diagram)
90-tan (16/.182) = theta
step 3 = Get the tension by adding the Forces on the y axes. See diagram
First problem (sail boat)
check the attachment
Fx = F(east) - F(northwest)Xcos45 = -12339 N
Fy = F(northwest)Xsin45 = 39739 N
Fnet = Squareroot of (Fx^2 + Fy^2)
then, Fnet = ma
a = Fnet/mass = 3.4 m/s
1st step is to draw a gaussian surface
2nd step is to find the flux = EA = E 2(pi)(r^2)
3rd step is to find the charge from the equation, rho = Q/V ; Q = rho * Volume =
(rho)[(2)(pi)(r^2)(d)]
4th step is to use gauss law, EA = Q/8.85X10^-12 and solve for E.
Epsilon = 8.85X10^-12
