Adrawing of electric field lines will immediately reveal (1) the relative magnitude of different charges (proportional to the number of lines that begin or end on each), (2) the sign of different charges (since lines go into negative charges and come out of positive charges), (3) the relative magnitude of the electric field at any point (because the magnitude of the field is proportional to how closely spaced the field lines are), and (4) the symmetry of the charge distribution (since they match the symmetry of the underlying field).

sfjjA)rule 1,3,5 are brokenB)rule 2,3 are brokenC) rule 2 are brokenD) rule 2,3 are brokenE)rule 2 are brokenF)noneG) rule 3,4 are brokenH) rule 2,4,5 are broken

Explanation:

This solution were gotten by examining the diagrams and figuring out the rules that are broken

For A

we see that the two charges are positive so rule 1 is broken,on the same diagram we see that there is no radial symmetry close to the charge so rule 3 is broken then looking again at the diagram A we can see that the electric field is not tangent to any electric line at any point hence rule 5 is broken

For B:

We see that the number of lines are not proportional to the magnitude of the charge hence rule 2 has been broken

secondly looking again at the diagram we see that the line are not uniformly distributed near the charge hence rule 3 is broken

For C:

We see that the number of line is not proportional to the magnitude of the charge hence rule 2 is broken.

For D:

we see that the number of lines are not proportional to the magnitude of the charge hence rule 2 has been broken

secondly looking again at the diagram we see that the line are not uniformly distributed near the charge hence rule 3 is broken

For E:

We see that the number of line is not proportional to he magnitude of the charge hence rule 2 is broken.

For F

Looking at the diagram we see that none of the rules are broken

For G:

looking at the diagram we see that the line are not uniformly distributed near the charge hence rule 3 is broken

taking another look at the diagram we see that the spacing of the lines are not indicating the magnitude of the charge hence rule 4 is broken

For H:

We see that the number of line is not proportional to he magnitude of the charge hence rule 2 is broken.

taking another look at the diagram we see that the spacing of the lines are not indicating the magnitude of the charge hence rule 4 is broken

Looking again at the diagram we see that the at any point on the electric field line that the electric field itself is not tangent to the electric field line hence rule 5 is broken

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.

From center station, a train departs every 30 minutes on the fast line and a train departs every 50 minutes on the state line. if two trains depart from center station at 8: 00 a.m., one on each of the two lines, what is the next time that two trains, one on each line, will depart at the same time?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.
