Answer:
The term Accuracy means that how close our result to the original result.
Suppose we do any experiment in laboratory and we calculate mass = 7 kg but answer is mass = 15 kg then our answer is not accurate.
And the term Precision means how likely we get result like this.
Suppose we do any experiment in laboratory and we calculate mass five times and each time we get mass = 7 kg then our answer is precised but not accurate.
Answer:
Coaching or mentoring
Coaching or mentoring can share similar qualities to hands-on training, but in this type of employee training, the focus is on the relationship between an employee and a more experienced professional, such as their supervisor, a coach, or a veteran employee.
The one-on-one mentoring style creates a relationship between employees that carries far beyond training. Lecture-style training
Important for getting big chunks of information to a large employee population, lecture-style training can be an invaluable resource for communicating required information quickly.
However, use this type of employee training sparingly.

Given:
Pressure, 
= 1300 kPa
Temperature, 
= 
= 100 kPa
velocity, v = 40 m/s
A = 1
Solution:
For air propertiess at
= 1300 kPa
=
= 793kJ/K
= 
and also at
= 100 kPa
= 401 KJ/K
= 
a) Mass flow rate is given by:
Now,
= 46.51 kg/s
b) for the power produced by turbine, 
= 18.231 MW
