Answer:
Distance between two point charges, r = 0.336 meters
Explanation:
Given that,
Charge 1, 
Charge 2, 
Electric potential energy, U = -0.5 J
The electric potential energy at a point r is given by :



r = 0.336 meters
So, the distance between two point charges is 0.336 meters. Hence, this is the required solution.
Answer:
In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
Explanation:
BOOM!!!
Protons have a positive energy charge, while neutrons have a neutral charge
The type of reaction that occurred in the test tube is ACID BASE REACTION.
Acid base reaction is a type of chemical reaction in which an acid and a base react together to form salt and water molecules. It is also known as neutralization reaction. For the question given above, the applicable chemical reaction is as follows:
HF + NaOH = NaF + H2O
From this chemical reaction, it can be seen that, hydrogen fluoride, which is a weak acid react with sodium hydroxide which is a strong base to produce sodium fluoride, which is a salt and a molecule of water.
Answer:
False because igneous rocks are formed from a volcano and sedimentary never move they stay in one spot
