The answer has to be c because the freezing and melting points cannot physically be the same
Answer:
The frequency of this light is .
Explanation:
Wavelength of the light =
Speed of the light = c =
Frequency of the light =
The frequency of this light is .
According to the kinetic molecular theory for an ideal gas, all gas particles "<span>have collisions that decrease the total energy of the system" but this is not always the case. </span>
Explanation:
It is known that 1 SCF produces approximately 1000 Btu of thermal energy.
As it is not mentioned for how many hours the gas is used in this process. Therefore, we assume that the total number of hours natural gas used in this process are as follows.
= 8760 hours
Now, we will calculate the annual cost of natural gas used in the process as follows.
= 555384000 SCF
Hence, annual cost of natural gas used in this process = loss of thermal energy
This will be equal to,
= 555,384,000,000 BTU
Thus, we can conclude that the annual cost of natural gas used in the process is 555,384,000,000 BTU.
Both the elements combine together due to incomplete outermost shell.
Two atoms of element Q mixed with element E in order to achieve stability because both the elements have incomplete outermost shell which make them very reactive. In element E we can see that it has 7 electrons while on the other hand, element Q has 5 number of electrons.
For gaining stability, each element has to reach 8 electrons so that's why both the elements react with each other and get stability so we can conclude that both the elements combine together due to incomplete outermost shell.
