Although it contributes only 0.02 percent to Earth's total mass, the water in Earth's oceans is still quite massive. Suppose the water of the
oceans could somehow be drained, kept in liquid form, and moved as
far from Earth as the moon is. How large would the gravitational force
between the water and Earth be? Assume the mass of the ocean's water
to be 1.4 x 1021 kg, the mass of Earth to be the same with water (5.98 X
1024 kg), and the Earth-moon distance to be 3.84 x 10 m.

The correct choice is c

Good moring let me you on this question the answer the electric force  have a good day ; )

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
