Answer:
The answer would be stress
Explanation:
A force that acts on rock to change its shape or volume is stress. Stress adds energy to the rock. The energy is stored in the rock until it changes shape or breaks. Three different kinds of stress can occur in the crust—tension, compression, and shearing.

atoms are made of 3 types of sub atomic particles; neutrons, protons and electrons
atomic number is the number of protons which is characteristic for the element. Atoms of the same element have the same number of protons.
mass number is the sum of the neutrons and protons.
Isotopes are atoms of the same element with different mass numbers. since they are the same element number of protons are the same but number of neutrons vary.
therefore 2 isotopes are of the same element so they have the same number of protons.
Answer:
20% of phosphorus
Explanation:
A fertilizer is used to improve the fertility of soils. Most fertilizers contains the element nitrogen, phosphorus and potassium.
They are often designated NPK fertilizers.
Now we know that the numbers 10-20-20 depicts the nitrogen-phosphorus and potassium content of the fertilizer.
From the designation,
The actual percentage is 20% of phosphorus.
10% of nitrogen
20% of potassium
Answer:
their ability to conduct heat and electricity.
Explanation:
Answer:
1 - e, 2 - k, 3 - a, 4 - i, 5 - b,
Explanation:
The ratio of the amount of analyte in the stationary phase to the amount in the mobile phase. --- Retention factor.
Time it takes after sample injection into the column for the analyte peak to appear as it exits the column. -- Retention time
The process of extracting a component that is adsorbed to a given material by use of an appropriate solvent system. -- Elution
Measure of chromatographic column efficiency. The greater its value, the more efficient the column. -- Theoretical plate number
Gas, liquid, or supercritical fluid used to transport the sample in chromatographic separations. -- Mobile phase
Immiscible and immobile, it is packed within a column or coated on a solid surface. -- Stationary phase
