Answer:
Entropy generation==0.12 KW/K
Explanation:



Mass flow rate= 


mass flow rate=
So by putting the values
Mass flow rate=2.97 kg/s
So entropy generation=(2.97)(0.0412)
=0.12 KW/K
Answer:
the ability to absorb or avoid damage without suffering complete failure and is an objective of design, maintenance and restoration for buildings and infrastructure
Explanation:
B. watch your surroundings
Solution :
The spring is expanded by 2 times of the block when it moves down an inclined by x times.
Here,
= 39 mm
= 225 mm
a). From the work energy principal,
Work forces = kinetic energy





b). calculating the distance travelled by the block before it comes to rest.
Substitute the value of
in (1),






x = 0.20 m
