Answer: Option (b) is the correct answer.
Explanation:
It is known that in a gas, molecules are away from each other due to more kinetic energy between its particles. As a result, there are more number of collisions between them.
So, when we apply pressure on a gas then its molecules come closer to each other. Due to which there occurs decrease in its volume.
Thus, we can conclude that to investigate the compressibility of a gas increase the pressure on it.
Environmental selective pressures. In other words, natural selection took place. It was the environment that caused these changes. Birds on the islands with the most suitable traits for survival thrived while the birds that didn't die.
Max Planck was studying the emission of light by
hot objects. He believed that the hot objects did not emit energy continuously,
as would be expected if it were in the form of waves. Instead he suggested that
the object emits the energy in small, specific amounts called quanta. A quantum
is the minimum quantity of energy that can be lost or gained by an atom. He
proposed the following relationship between a quantum of energy and the
frequency of the radiation: E = hn.
E represents the energy in joules of a quantum of radiation, n<span> is the frequency of the radiation emitted, and
h is a constant known as Planck’s constant. Albert Einstein introduced the idea
that electromagnetic radiation has a dual wave-particle nature. Example: white
light exhibits many wavelike particles, it can also be thought of as a stream
of particles. Each particle of light carries a quantum of energy. He called
these particles photons. A photon is a particle of electromagnetic radiation
having zero rest mass and carrying a quantum of energy.</span>
OK now that’s a lot to ask for but if you want someone to actually do that you’re gonna need a lot more points
