Two long, charged, thin-walled, concentric cylindrical shells have radii of 4.3 and 7.0 cm. the charge per unit length is 4.8 × 10^-6 c/m on the inner shell and -6.4 × 10^-6 c/m on the outer shell. what are the (a) magnitude e and (b) direction (radially inward or outward) of the electric field at radial distance r = 6.1 cm? what are (c) e and (d) the direction at r = 12 cm?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
