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:
29 percent
Explanation:
The transportation sector is the highest contributing factor to greenhouse gas emissions in the world. Vehicles such as cars, motorcycles, airplanes, ships etc all emit these gases which causes global warming.
Electric cars is known not to little or zero direct emission and known to be safer. It however emits nitrogen oxide which is fog like in a very minute quantity.
Answer:
4.2
Explanation:
The "allowance" is the difference between the maximum shaft size and the minimum hole size.
maximum shaft = C +D = 8.5 +0.1 = 8.6
minimum hole = A -B = 4.8 -0.4 = 4.4
Allowance = 8.6 -4.4 = 4.2
__
For an interference fit, the allowance is negative.
Answer:
The heat transferred to water equals 1600 kJ
Explanation:
By the conservation of energy we have
All the kinetic energy of the moving vehicle is converted into thermal energy
We know that kinetic energy of a object of mass 'm' moving with a speed of 'v' is given by
Thus
Thus the heat transferred to water equals
