If a negative charge is released in a uniform electric field, it will move.

A. from low to high potnetial
B. in ciruclar motion
C. in the direction of the electric field
D. from high to low potential
E. In a direction perpendicular to the electric field

Will you chech and finish these for me, because i am stumped with them.

The material that keeps its new shape after it is stretched is called?

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.
