Answer:
Energy of a photon is
Explanation:
Given:
Frequency of the photon is, .
Energy of a photon of frequency is given as:
, where, is called Planck's constant.
So, energy of a photon is:
Therefore, the energy of a photon whose frequency is Hz is .
Answer:
When a sound wave moves from water to air, the speed of the sound wave decreases.
Explanation:
This is because the transfer of motion that produces the wave.
C.an equal and opposite reaction
Answer:
the ratio of marginal benefits to price should be identical across all goods.
Explanation:
In equilibrium, the ratio of marginal benefits to price should be identical across all goods.
marginal benefit is the the maximum amount of money a customer is willing to pay for an additional good or service. The consumer satisfaction tend to decrease as the consumption increases. And for equilibrium to exist the ratio of marginal benefits to price should be identical across all goods
Answer:
<h2><em>Potential energy.</em></h2>
Explanation for yall who dont get:
Basically, the energy that is changing during a phase change is potential energy. Why? Cuz, during a phase change, the heat added (Potential Energy INCREASES) or released (Potential Energy DECREASES) allow the molecules to move apart or be together.
