One surface of an infinitely large ideal conductor plate is at the planex -0 of the Cartesian coordinate system, with the x-y plane being the plane of the paper and the z axis represented by the dot, as shown in the figure. The conductor plate is grounded (i.e. at a potential 0). A positive point charge O is located at (d, 0, 0). Assuming free space (i.e. vacuum, with permittivity &o). find the following: (1) The electric field and potential...
3. Polar Coordinates. (a) Given a rectangular coordinate point (x, y), how do you compute the equivalent polar coordinates: (r, 0)? (b) Given a polar coordinate (r, o), how do you compute the equivalent rectangular coordinate: (x, y)? (c) Consider the drawing in Figure 1. Compute the coordinate of each small circle. (d) What if the circle is centered at the point (cx, cy) (and not the origin). How does the formula change?
a) Consider a coordinate system where the x and y coordinates are both zero when the ball passes through the pivot and lands on the top of the table at that same level (y = 0). The ball then starts at y = 0 and reaches y = 0 again when landing on the table. The range R will simply be the x coordinate where it hits. Draw your theoretical quantitative predictions for the range R as a function of...
1.12 marks Suppose the measurements of ore lode in a deposit of gold are described by the func- L(x,y,z)-(10 32-y - 3y +0.4ry), where z is the vertical coordinate, with z = 0 at the surface and z < 0 being below ground. The tion (z+3)2 distances are measured in tens of metres (a) Draw contours of the function at a depth of z-3. Use Matlab, Octave or similar. You might like to include the range [x,y] E (-5,5) (b)...

(a) f'(x) > 0. and F"(x) > 0 (b) f'(x) <0. and f"(x) = 0 (c) f'(x) = 0.and f"(x) < 0 6. (12pts) Find all critical numbers of f(x) = x + Then use the second-derivative test on each critical number to determine whether it leads to a local maximum or minimum. Show your work to get a full...
A lamina occupies the part of the rectangle 0≤x≤3, 0≤y≤7 and the density at each point is given by the function ρ(x,y)=5x+6y+4. A. What is the total mass? B. Where is the center of mass?
Consider the following initial value problem, (1 - z2)y"+zy' - 12y-0, (0)3, y' (0)-0. Note: For each part below you must give your answers in terms of fractions (as appropriate), not decimals (a) This differential equation has singular points at Note: You must use a semicolon here to separate your answers. (b) Since there is no singular point at z 0, you can find a normal power series solution for y(x about z0,i.e. m-0 As part of the solution process...
