The changes in internal energy of the system <u>75.1 J.</u>
The internal energy of a thermodynamic system is the total energy contained in it. It is the energy required to create or prepare a system in a given internal state and includes contributions of potential energy and internal kinetic energy.
Calculation:
Internal energy = 162.4 j - work done
= 162.4 j - 87.3 j
=<u> 75.1 J</u>
<u />
Internal energy, in thermodynamics, is the property or state function that defines the energy of matter in the absence of capillary action or external electric, magnetic, or other fields.
Internal energy is the microscopic energy contained in the matter given by the random and disordered kinetic energy of the molecules. It also includes the potential energy between these molecules and the nuclear energy contained in the atoms of these molecules.

What’s the weight and how high is the clif
Answer: Physical is the blank space
Explanation: Your welcome
Explanation:
P= rho×g × h (g=10 m/s²) ,
(rho=1000 kg/m³)
P= 1000×10×5= 50,000 N/m² (C)
Answer:
Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C
Explanation:
given,
surface charge (q) = 3.3 × 10⁻⁶ C
to calculate electric flux = ?
a) radius = 0.76 m
area of sphere = 4 π r²
electric flux = 
electric flux = 
flux = 0.373 × 10 ⁶ N m²/C
electric flux in the other two cases will also be same as electric flux is independent of area
so, Electric flux in a) , b) and c) is same which is 0.373 × 10 ⁶ N m²/C
