(a) a consequence of the average potential theorem is that all extrema of the electric potential occur on the boundary surface s of a volume v. use this together with gauss' law to prove that for a charge-free region of space whose boundaries have well defined potentials, the solution to laplace's equation is unique 2. 5] (b) apply the uniqueness theorem in part (a) to calculate the surface charge density that is induced on a grounded conducting plate of infinite extent (of finite thickness) when a point charge q is placed at a distance d above the plate. the potential positionfdue to a point [9] [hint: you may need to use the result at charge q at position , v(r)= q/(4te- )] (c) what is displacement current and why is it a necessary modification to ampere's law in arriving at maxwell's equations

An important dimensionless parameter concerned with very high-speed flow is the mach number, defined as v/c, where v is the speed of the object such as an airplane or projectile, and c is the speed of sound in the fluid surrounding the object. for a projectile traveling at 1170 mph through air at 50 ˚f and standard atmospheric pressure, what is the value of the mach number?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
