Lithium atomic number = 3
Li atom has 3 protons,3 electrons.Then it has no charge.
So the charge of Li atom here is zero.
<u>Option b: 0 is the right answer.</u>
Answer:
200 W
Explanation:
Formula of Power is
P= W/T
where
W= Work and T= Time
so
4000/20 = 200J/s or 200 W
Answer:
Technician B.
Explanation:
The claim of technician B that the PCM will add fuel if the IAT indicates that the incoming air temperature is cold is correct.
For a given peak intensity of radiation of a star that occurs at a wavelength of 2 nanometers, this is located at the spectral band of an X-ray. An X-ray's wavelength typically goes from 0.1 nano meters to 10 nano meters. Given that, the wavelength of the star fits perfectly into the range of an X-ray
