Answer: Option (C) is the correct answer.
Explanation:
An atom consists of three subatomic particles which are protons, neutrons and electrons.
The protons and neutrons are present inside the nucleus. Whereas electrons revolve around the nucleus.
Whenever there is a bond formed by loss, gain or sharing between any two atoms then it is due to the electrons.
Hence, we can conclude that atoms may be bonded together by losing, gaining, or sharing electrons.

Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that
Potential well dimension =
Mass of electron
So energy required to electron to jump from ground state to 3rd state
Answer:
6 kg
Explanation:
F=ma
F is Force(newtons)
m is mass(kg)
a is acceleration(m/s^2)
Plug in the numbers
3000 = m(500)
divide both sides by 500 to cancel out the 500.
3000/500=6
6 = m
6kg is the mass
Answer:
28.75 %
Explanation:
porosity is the term which is defined as the volume of voids present in the soil to the total volume of the soil.
it is denote by n where
A porous material is one which contain pores, if a material is porous it will allow the water to pass through it.
the porosity of the gravel sample is 28.75%
