Answer:
divergent
Explanation:
Plates move apart at a divergent boundary
Density is the measure of a material's mass per unit volume, used in many aspects of science, engineering and industry. Density can be calculated by dividing an object's mass by its volume. Since different materials have different densities, measuring an object's density can help determine which materials are in it. Finding the density of a metal sample can help to determine its purity.When measuring liquids and regularly shaped solids, mass and volume can be discovered by direct measurement and these two measurements can then be used to determine density. Using a pan balance, determine and record the mass of an object in grams. Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object's mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.

Answer:
PH scale is a universal indicator of strongness of base and acid
Answer:
quantum mechanical theory; it says that quantized energy makes the location of electrons uncertain
Explanation:
According to the wave particle duality theory, particles have wavelike properties and vice-versa.
We can not measure both the velocity and position of a particle simultaneously.
The quantum mechanical model now introduces the idea that the electron is not localized at a particular position within the atom. Hence, the exact location of the electron within the atom is uncertain. This is quite in line with the Heisenberg uncertainty principle
