In a spherical metal shell of radius r, an electron is shot from the center directly toward a tiny hole in the shell, through which it escapes. the shell is negatively charged with a surface charge density (charge per unit area) of 6.40 × 10^-13 c/m^2. what is the magnitude of the electron's acceleration when it reaches radial distances (a) r = 0.690 r and (b) 2.00r?

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction

Your answer would be, the due process clause of the 14th., and 5th. amendments differ the clause in the 14th. amendment has been interpreted, to mean that state government must provide some of the protections within the bill of rights.your answer would be, the clause in the 5th. amendment was specifically written to restrict a new powerful government.hope that !
