I switched the result of [m2][m1] with where [m3] was suppose to be. Thanks for you help, so here is what I have for my mFinal: mfinal = \left(\begin{array}{cc} 2.675 + di & 16.75 -.67di\\ -.067 & .67\\ \end{array} \right) the negetive I have from my m2 matrix, I posted...

I did it that way and that is how I got mFinal. I don't know if my math is not right or if something else is not right.

I multiplied [m1] [m2] I then took the result and multiplied it by [m3].

Homework Statement The problem is: The left end of a long glass rod 10.0 cm in diameter, with an index of refraction 1.5, is ground and polished to a convex hemispherical surface with a radius of 5.0cm. An object in the form of an arrow 2.00mm tall, at right angles to the axis of the rod, is...

would you calculate Z the same way with the capaicitor and reisitor in parrallel?

How do I figure out energy/time? would this be (16800 x 10 x 10^-3) or about 168 watts where 16800 is the total voltage of the transformer and 10 x 10^-3 is the current? with part c would this be 140 times greater than the current in the second transformer?

A resistor with a resistance of 500 ohms and a capacitor with with a capacitance of 2 x 10^-6 f are connected in parrallel to an ac generator that supplies an rms voltage of 260 v at an angular frequency of 377 rad /s find the current amplitude in the resistor (Ir)peak. I know I have to...

I have a homework question that states: A transformer connected to a 120 V rms ac line is to supply 16800 V(rms) for a neon sign. To resuce shock hazard, a fuse is to be inserted in the primary circuit; the fuse is to blow when the current in the secondary circuit exceeds 10.0mA. a) What is the...

I have been trying to figure out what the equation is for this problem: A glass tube filled with gas has electrodes at each end. When a sufficiently high potential difference is applied between the two electrodes the gas ionizes; electrons move towards the positive electrod, and the positive...

I got E by \sigma = 25 * 10^-6 C/m^2 then I took that and divided by 2e0 with e0 being 8.85 *10^-12 I took that answer(1.4 * 10^6) and multiplied it by the charge of the ball which is 3 X 10^10 C which gave a force of 4.23 X 10^-4.

okay so if I am correct I would take the atan of my answer and get about 6.2 degrees is this correct?

a small .4g sphere carries a charge of 3 X 10^-10 and is attached to one end of a silk fiber 8cm long. The other end of the fiber is attached to a large vertical insulating sheet that has surface charge density equal to 25 X 10 -6 C/m^2. The sphere on the end of the fiber is repelled outward and...

I have a physics question that states: An amount of positive charge is distributed uniformly along the positive y-axis between y=o and y=a. A negative point charge -q lies on teh positive x=axis a distance r from the origin. Derive the x and y compontes of the force that the charge distribution...

thank you for the help.

I believe this is the right place for this question. I am strugling with getting this homework problem setup. The question is: A charge q1 = -3 nc is placed at the origin of an xy-cordinate system, and a charge q2=2.00nC is placed on the positive y Axis at y=4cm. If a third charge q3 =4nC is...
