Its the second one. Add the exponents and you'll get 7
Protons is the number of the element on the periodic table. Electrons are the same number of protons and i'm sorry I do not know neutrons, I hope I helped!
Answer:
The speed of an electron is 0.01908 m/s.
Explanation:
De-Broglie wavelength is given by:
where, = wavelength of a particle
h = Planck's constant =
m = mass of particle
v = velocity of the particle
Velocity of an electron = v
Mass of an electron =
Wavelength of electron is twice the displacement in seconds which is velocity of an electron.
Then.wavelength of an electron =
v = 0.01908 m/s
The speed of an electron is 0.01908 m/s.
Answer:
Cellular respiration.
Explanation:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Because the chemicals are different
