Answer and Explanation:
The crack formation growth that takes place in an environment corrosive.
Stress corrosion cracks can be defined as the spontaneous failures of the metal alloy as a result of the combined action of corrosion and high tensile stress.
Some of the characteristic features of stress corrosion cracks are:
- These occur at high temperatures.
- Occurrence of failures in metals mechanically.
- Occurrence of sudden and unexpected failures under tensile stress.
- The rate of work hardening of the metal alloy is high.
- Time
- An environment that is specific for stress corrosion cracking.
They do in fact heat up while receiving energy.
Answer:
investor claim is acceptable
Explanation:
given data
Win = 0.25 kW
Qc = 3000 J/s = 3kW
Th = 293 K
Tc = 270 K
solution
we get here coefficient of performance of cycle is
coefficient of performance = 
..................1
put here value and we get
coefficient of performance = 
coefficient of performance = 1.2
and
coefficient of performance of ideal refrigeration is
coefficient of performance = 
..................2
coefficient of performance = 
coefficient of performance = 11.74
and
we can see here that coefficient of performance of ideal refrigeration is is more than real cycle coefficient of performance
so investor claim is acceptable
