Answer:
The number of electrons transferred from one ball to the other is 2.06 x 10¹² electrons
Explanation:
Given;
magnitude of the attractive force, F = 17 mN = 0.017 N
distance between the two objects, r = 24 cm = 0.24 m
The attractive force is given by Coulomb's law;

The charge of 1 electron = 1.602 x 10⁻¹⁹ C
n(1.602 x 10⁻¹⁹ C) = 3.298 x 10⁻⁷

Therefore, the number of electrons transferred from one ball to the other is 2.06 x 10¹² electrons
Answer:
5 . the correct answer is option 3rd , these continents were once single landmass !
6. correct answer is option 2nd ! Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e. estimated age). In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.
B. An increase in your mass
Because acceleration is inversely proportional to the mass of the object.

By raising a position of an object, Its potential energy increases.
