Answer: A degenerate pressure will generate a large force to repel further compression.
Explanation: In the production of new stars from the core of old dying white dwarf stars, the inner parts of the star will experience contraction with the release of heat , as they contract, their atoms will be squeezed such that their electrons start to overlap, and because of the Pauli's exclusive principle which states that no two electrons can occupy same space, the electrons will begin to repel each other and an opposing pressure called degenerate pressure will create a force so that the electrons cannot continually be crushed or overlap. With the limit of contraction, the outer parts of the star will expand and be repelled releasing the old stars called nebula and creating space for the inner new stars to form.
Answer:
Answer is A
Explanation:
Important physical properties that affect fertility include soil structure and texture. Structure is the amount of aggregation and pores in soil and texture is the proportion of clay and sand particles in soil. Both affect soil fertility by affecting water movement through soil, root penetration and water logging.
For the volume of a solid or liquid
Density = mass/ volume so
volume = mass / density
For the volume of a liquid
Moles = volume x concentration
Volume = moles / concentration
For the volume of a gas
Volume = moles x 24
There are many other formulas as well :)
Answer:
A.
Explanation:
melting of ice will increase water in oceans due to which water in oceans will increase and salinity will decrease. hence, melting of ice caps near the north pole affects salinity of the ocean
