Water molecules are made of slightly positively charged hydrogen atoms and slightly negatively charged oxygen atoms. which force keeps water molecules stuck to one another?
a.) strong nuclear
b.) gravitational
c.) weak nuclear
d.) electromagnetic

D. Electromagnetic is what holds the H2o molecules together.

D) Electromagnetic Force

Explanation:

As we know that when two charged particles are placed at some distance from each other then the force between the charge particles is given by Coulomb's law

It is given by the equation

so here we can say that whenever two charges are separated by some finite distance then they exert electrostatic force on each other

This force would be attraction force if two charges are opposite in sign and this force will be repulsive force if the charges are of same sign

Since here hydrogen and oxygen atom is having few positive and negative charges on them so the force between them is electromagnetic force

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
