Answer: Option (c) is the correct answer.
Explanation:
It is known that the expression for potential energy related to charges and distance between their separation is as follows.
where, 
and 
are two charges
r = distance of separation between the charges
k = electrostatic constant
So, when both the charges are carry the same charge and r is small then the value of potential energy will be positive in nature.
Whereas if the distance of separation between the charges is infinitely large then the potential energy calculated will be zero everywhere.
Thus, we can conclude that the statement one object is negatively charged and the other one is positively charged, is incorrect.
Answer:
more inelastic
Explanation:
Assume the price of gasoline doubles tonight and remains at that price for the next two years. The price elasticity of demand for gasoline measured tomorrow will be <u>more inelastic</u> when compared with the price elasticity of demand for gasoline measured two years from now.
Inelastic refers to the static quantity of a good or service when its price changes.
The ballerinas takes advantage of the moment of interia by not stretching her hands out etc. and by doing so decreasing the moment of interia and therefore a smaller torque is produced to rotate at a faster rate.
It’s B. Na+2 HOPE THAT HELPED!
C. Usually when an atom loses or gains an electron, it is because it is trying to satisfy the Octet Rule. The Octet Rule states that an atom is at its stablest when it has 8 valence electrons (two in helium's case)
If you look on the periodic table, elements on the left (Alkaline Metals) are the most reactive because they only have one valence electron (or electron in the outer shell). Elements on the right (Noble Gases) are the least reactive because they have a full outer shell of 8 valence electrons.
Later on you will find that as stability decreases as you go down the periodic table but that is a discussion for a different time.
