The distance between a charge and the source of an electric field changes from 3 mm to 6 mm. As a result of the change, the electric potential energy of the charge is

Alkaline earth metals are found in group 2 of the periodic table.

An atom that has fewer electrons that protons is called a positive ion.

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.
