I'm still not very confident in analyzing circuits. Here's what I know: 1) v_o=v_IN - v_T 2) id=k/2*(v_IN-v_T)^2 3) v_o=v_S-(k/2)(v_IN-v_T)^2*RS 4) v_o = v_S-id*Rs iDS = v_o/RS The answer I chose in the photo was based off of other online discussions. I'm very confused and don't have the...

Right! Thanks.

Wouldn't it just be the three since your given all the resistances available in the set E12?

The link is an image with the question and circuit representation: http://i49.tinypic.com/2mmwg8l.png Here are the equations I used: V_out/V_in = R_2/(R_1 + R_2) {using the node method} R_thevenin (R_th) = R_2*R_1/(R_1+R_2) And given the conditions => 10 < R_th < 30...

Thank you, I found out what I was doing wrong.

A stationary destroyer is equipped with sonar that sends out pulses of sound at 30.000 MHz. Reflected pulses are received from a submarine directly below with a time delay of 60 ms at a frequency of 29.958 MHz. (a) If the speed of sound in seawater is 1.55 km/s, find the depth of the...

So the integral is gross?

If C is the curve given by r(t)=<1+3sin(t), 1+5sin^2(t), 1+5sin^3(t)>, 0≤t≤π/2 and F is the radial vector field F(x, y, z)=<x, y, z>, compute the work done by F on a particle moving along C. Work= int (F dot dr) If F is the potential function(?), do I integrate F with respect to each...

Q1) The amplitude of an electromagnetic wave is E0 = 471.0 V/m. Find the following values. (a) Erms 333.047 V/m (b) Brms __ nT (c) the intensity I __W/m2 (d) the radiation pressure Pr __nPa Q2)(a) For a given distance from a radiating electric dipole, at what angle (expressed...

Thank you!

Use cylindrical coordinates to evaluate the triple integral , sqrt(x^2+y^2) where the region integrated is the solid bounded by the circular paraboloid z=9-16(x^2+y^2) and the xy-plane. I'm having trouble deciding what the bounds for r would be.

I found my error. Thank you for replying.

The figure below shows two long, straight wires in the xy plane and parallel to the x axis. One wire is at y = −6.0 cm and the other wire is at y = +6.0 cm. The current in each wire is 19 A. If the currents are both in the −x direction, find the magnetic field at the following points on the y...

The answer is asked to be given as a vector.

Q:What is the force on an electron that has a velocity equal to 2e6 m/s i - 3e6 m/s when it is in a region with a magnetic field given by 0.75 T i + 0.45 T j - 0.60 T k? F=q(v X B) I took the determinate of the electron's velocity and magnetic field and came up with <1.8e6,1.2e6,3.15e6>...
