Answer:
Explanation:
Given
Volume of fixed chamber
Initial Temperature
Final Temperature
Heat Supplied
From First law of thermodynamics
Change in internal energy of the system is equal to heat added minus work done by the system
as the volume is fixed therefore work
thus
for mono-atomic gas is
and 1 mole contains
thus No of molecules
No of molecules
Answer:
The charge on the dust particle is
Explanation:
From the question we are told that
The length is
The width is
The charge is
The mass suspended in mid-air is
Generally the electric field on the carpet is mathematically represented as
Where is the permittivity of free space with value
substituting values
Generally the electric force keeping the dust particle on the air equal to the force of gravity acting on the particles
