Answer:
Volume of face centered cubic cell=
Explanation:
Consider the face centered cubic cell:
1 atom at each corner of cube.
1 atom at center of each face.
Consider the one face (ABCD) as shown in attachment for calculation:
Length of the all sides of face centered cubic cell is L.
Volume of face centered cubic cell= L^3
Now Consider the figure shown in attachment:
According to Pythagoras theorem on ΔADC.
(a is the atomic radius)
(Put in the formula of Volume)
Volume of face centered cubic cell= L^3
Volume of face centered cubic cell= 
Volume of face centered cubic cell= 
Volume of face centered cubic cell=
Answer:
Cost = $2527.2 per month.
Explanation:
Given that
Discharge ,Q = 130 L/min
So

Cost = $0.45 per cubic meter
1 month = 30 days
1 days = 24 hr = 24 x 60 min
1 month = 30 x 24 x 60 min
1 month = 43,200 min
Lets x
x = 0.13 x 43,200

So the total cost = 5616 x 045 $
Cost = $2527.2 per month.

Answer:
Time taken by airplane to cover given distance = 2 hour
Explanation:
Given:
Distance cover by airplane = 1,000 miles
Velocity of airplane = 500 miles per hour
Find:
Time taken by airplane to cover given distance
Computation:
Time taken = Distance / Velocity(Speed)
Time taken by airplane to cover given distance = Distance cover by airplane / Velocity of airplane
Time taken by airplane to cover given distance = 1,000 / 500
Time taken by airplane to cover given distance = 2 hour
