Answer: 
= 28800 Pa or 28.8 kPa
Explanation: To determine the pressure of a liquid in a rotating tank,it is used:
p = 
- γfluid . z + c
where:
is the liquid's density
w is the angular velocity
r is the radius
γfluid.z is the pressure variation due to centrifugal force.
For this question, the difference between a point on the circumference and a point on the axis will be:
= 
- γfluid.
- (
- γfluid.
)
= 
- γfluid( -)
Since there is no variation in the z-axis, z = 0 and that the density of oil is 0.9.10³kg/m³:
=
= 28800
The difference in pressure between two points, one on the circumference and the other on the axis is = 28800 Pa or 28.8 kPa
Answer:
(A) Adding Nitrogen
Explanation:
R11 or R123 are flammable substance under certain conditions when mixed with Oxygen, adding Nitrogen is a safety procedure used in displacing any R11 or R123 which are considered as hazardous when mixed with Oxygen.
Answer:
Which human resource skill helped Alex convince the client? its nagotiation
Explanation:
got it right on the test.
The answer is C because the word graphic means picture.
Answer:
void bubble_sort( int A[ ], int n ) {
int temp;
for(int k = 0; k< n-1; k++) {
// (n-k-1) to ignore comparisons of already compared iterations
for(int i = 0; i < n-k-1; i++) {
if(A[ i ] > A[ i+1] ) {
// swapping occurs here
temp = A[ i ];
A[ i ] = A[ i+1 ];
A[ i + 1] = temp ;
}
}
}
}
