Answer:
a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall—to generate electricity.
Explanation
Answer:
Temperature
Explanation:
Because Temperature is a measure of the average kinetic energy of all the molecules in a gas. As the temperature and, therefore, kinetic energy, of a gas changes, the RMS speed of the gas molecules also changes. The RMS speed of the molecules is the square root of the average of each individual velocity squared.
Answer : The frequency of a photon of radiation is,
Explanation : Given,
Wavelength of the radiation = 670.8 nm
First we have to convert wavelength form 'nm' to 'm'.
Conversion used :
So, the wavelength of the radiation = 670.8 nm =
Now we have to calculate the frequency of a photon of radiation.
Formula used :
where,
= frequency of a photon of radiation
= wavelength of the radiation
c = speed of light =
Now put all the given values in the above formula, we get the frequency of a photon of radiation.
Therefore, the frequency of a photon of radiation is,
Answer:
The answer is
<h2>4.5 × 10²²</h2>
Explanation:
To find the number of atoms of titanium , given it's number of moles we use the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 0.075 mol
We have
N = 0.075 × 6.02 × 10²³
We have the final answer as
<h3>4.5 × 10²²</h3>
