Aparallel-plate capacitor is constructed of two square plates, size l×l, separated by distance d. the plates are given charge ±q. let's consider how the electric field changes if one of these variables is changed while the others are held constant. part a what is the ratio e(final)/e(initial) of the final to initial electric field strengths if q is doubled?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
