Answer:
Temperature change is 0.0345 degree rankine
The change in temperature is therefore small
Explanation:
Please see attached for the workings.
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:
150 W
Explanation:
Power is energy per unit time. The power generated by the engine is ...
(3000 J)/(20 s) = 150 J/s = 150 W
The engine generated 150 watts.
Answer:
x=2.19in
Explanation:
This is the equation that relates the force and displacement of a spring
F=Kx
m=mass=12.5lbx1slug/32.14lb=0.39slug
F=mg=0.39*32.2=12.52Lbf
then we calculate the spring count in lbf / ft
K=F/x
K=5.7lbf/1in=5.7lbf/in=68.4lbf/ft
Finally we calculate the displacement with the initial equation
X=F/k
x=12.52/68.4=0.18ft=2.19in
