How does the electrostatic force compare with the strong nuclear force in the nucleus of an atom? a. the electrostatic force is only repulsive and acts over longer distances. b. the electrostatic force acts over shorter distances and is weaker. c. the electrostatic force acts over longer distances and is stronger. d. the electrostatic force is only repulsive and acts over shorter distances.

The correct option is A.
In the nucleus of an atom, the nuclear force, which bind the protons together is very strong and powerful at short distances. The repulsive electrostatic force, which exist between the protons is comparatively weaker. But as the distance of the atom shells increases, the nuclear force becomes weaker while the electrostatic force becomes stronger.

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.
