Explanation:
1.
Given parameters:
Frequency of the radiation = 8.4 x 10¹⁴Hz
Unknown:
Energy of the wave = ?
Solution:
The energy of a wave is given by the expression below;
E = hf
E is the energy
h is the Planck's constant = 6.63 x 10⁻³⁴m²kg/s
f is the frequency
Now insert the parameters and solve;
E = 6.63 x 10⁻³⁴m²kg/s x 8.4 x 10¹⁴Hz
E = 5.57 x 10¹ x 10⁻²⁰J
E = 5.57 x 10⁻¹⁹J
2.
Given parameters:
Wavelength = 2.13 x 10⁻¹³m
Unknown:
Frequency of the wave = ?
Solution:
The frequency of a wave can be determined using the expression;
C = f∧
C is the speed of light = 3 x 10⁸m/s
f is the frequency
∧ is the wavelength
f = = = 1.41 x 10²¹hz
The molecules of propane gas slow down as the gas is compressed. As a result, during liquefaction, a large portion of the kinetic energy lost by the propane molecule is released into the environment.
Thus, as we transition from a gas to a liquid, our molecules get closer to one another. And because our particles are moving from being far apart to being close to one another in the liquid form, we will see an increase in the intermolecular forces as our molecules become more attracted to one another. And since we're effectively creating bonds here, energy will be released. And utilizing Barth's barf, we may recall this. When bonds are broken, energy is absorbed. However, energy is released as bonds are created. We are now creating stronger ties as a result. We are therefore expending energy.
<h3>
What is liquefaction?</h3>
In physics and chemistry, the process of a solid turning into a liquid (also known as melting or condensation) is referred to as liquification. Melting point is a term used to describe the temperature and pressure at which a solid becomes a liquid (sometimes referred to as the liquefaction point).
<h3>
What is Kinetic energy?</h3>
Kinetic energy is the name for the force that pushes an object in motion. Its basic nature is that of a moving mass's energy. As a scalar quantity, kinetic energy merely conveys the amount of an event rather than its direction. It is unimaginably good.

Answer:
you need to show more thing cause we not going to know what we have to do
Explanation:
and show more detaills
<span>A) high to low pressure </span>
The higher in altitude the colder the temperature. Temp. drop 4°F every 1000 feet. That means that 75° at the bottom and 10000 feet up it will be 35°.
This colder temp does affect plant growth but it also affects the soil which in turn affects plant growth. Mountain vegetation (depending on the elevation) is comparable to the vegetation in areas of high latitude. Areas found up in the northern regions are affected by the colder temp as are the soils - same happens in mountainous areas.
You tend to see more evergreens and soils are more acidic and less rich (poor nutrients). You will also get your permafrosts. Eventually a treeline occurs - mountain tops become treeless as does the north arctic areas. You find mosses growing in and around the rocks with some shrubs whereever there is enough soil for the roots to take.
"An increase in altitude, such as climbing a mountain is similar to heading north (in the northern hemisphere) plant and animal species will be similar at a mountain top to those which are further north. "
Hope this helped can u mark me as brainlist plz
