Answer:
Electromagnetic waves transfer energy through vibrations of electric and in magnetic fields. For sound waves the energy is transferred through the vibration of air particles or particles of a solid. Waves also carry energy, the amount of energy they carry depends on their frequency and their amplitude. The more energy and the higher frequency amplitude, the more energy waves are ^‿^
1500m = 1 sec
9000m/1500 = 6
So, it would take 6 sec to go 9000m
A. an accelerating charged charged particle or changing magnetic fields
Degeneracy pressure arises when sub-atomic particles are packed as tightly as the laws of quantum mechanics allow an object becomes as small as or smaller than Earth.
Answer: Option A
<u>Explanation:
</u>
Degeneracy pressure is the outcome of quantum degeneracy. As stated by Pauli’s exclusion principle, that two electrons of same quantum number cannot occupy the single shell, this leads to compression of shells.
So when the shells are getting compressed, the pressure will be created in the nucleus due to this compression which will be opposing the compression of space of the subatomic particles.
So the more the sub-atomic particles will be packed tightly, the more degenerate levels will be created leading to more compression of size of the atoms even smaller than Earth. This leads to increase in the degeneracy pressure as the interaction will increase between the nucleus and delocalized electrons on decreasing the size of atoms.
Answer:
A derived unit is called so because it is the product of two more basic units. The basic unit of area is the cubic meter (m³) for volume. By derived unit, it refers to any given quantity which cannot be measured directly with any device. For eg., We can't measure density of a substance with a rule, or scale, or bucket.
