Answer:
B) m<1 + m<2 < m<2 + m<3 + m<4
Answer:
Some of the irreversibilities are listed below:
- Plastic deformation of solids
- Transfer of heat over finite difference of temperature
- When two fluids are mixed together the process is irreversible
- Combustion of a gas
- Current flowing through a finite resistor
- Diffusion and free compression or expansion of gas
- Relative motion of body with force of friction
- Processes involving chemical reactions(spontaneous)
Answer:
0.
Explanation:
To find the electrical force per unit area on each sheet we start defining our variables,



We find the electric field for each one, this formula is given by,

Substituting each value from the three charged sheets, we have



The electric field is



Force on each sheet is,


The total force is 0
