Calculate the electric field at the point x meters on the axis of the ring if the total charge on the ring = Q, and there is a point charge of strength q in the center of the ring. Given: Q = +39 nanocoulombs. q = -19 nanocoulombs. x = 1.5 m. Radius = a = 0.4 m.

The answer is b hope this

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.
