Answer:
Following are given the answers one-by-one with explanation:
(a) 8 records
As records are the horizontal rows of data and we have 8 of them.
(b) 5 fields
As fields are vertical columns of data and we have 5 of them.
(c)E3000
As by sorting Makers_names in ascending order the last one would be Rany and by sorting Processor_type we have two option with Rany that are B1500 and E3000. We can see that E3000 will come at the end.
(d) Computer_type
As only two choices (Laptop and PC ) are being used under the column computer_type so it can be amended to contain Boolean data.
(e) format check
This will check that the field should contain one alphabet (capital letter) followed by 4 digits each.
i hope it will help you!
Answer:
Input power of the geothermal power will be 686000 J
Explanation:
We have given density of brine
Rate at which brine is pumped
So mass of the pumped per second
Mass = volume × density = kg/sec
Acceleration due to gravity
Depth h = 200 m
So work done
Efficiency is given
We have to fond the input power
So input power
So input power of the geothermal power will be 686000 J

Answer:
14.27 mm
Explanation:
Force = 80 Newton
Pressure exerted = 5 bar = 5×10⁵ Pa
Pressure exerted = Force/Area
Area = Force/Pressure
Area of the cylinder=πd²/4
Hence diameter of cylinder 14.27 mm
