Answer:
This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate movement, collided. ... Artist's conception of the 6,000-km-plus northward journey of the "India" landmass (Indian Plate) before its collision with Asia (Eurasian Plate).

I think the correct answer would be option C. Adding one proton to an atom of lithium with 3 protons, 4 neutrons and 3 electrons would form a beryllium ion. The new atom have 4 protons and 4 neutrons since Be has a mass number of 9 then it has to form an ion.
Answer:
q2 = 9.02*10^{-4}C
Explanation:
To find the value of the other charge you use the Coulomb's law:
k: Coulomb's constant = 8.98*10^{9}Nm^2/C^2
q1: charge 1 = 55*10^{-6}C
r: distance between charges = 90cm = 0.9m
F: electric force = 550N
By doing q2 the subject of the formula and replacing you obtain:
hence, the value of the other charge q2 is 9.02*10^{-4}C
