Hello!
To solve this problem use the following steps, the procedure is attached.
1. draw the complete outline of the problem
2. Use the continuation equation that states that the volumetric flow at the inlet of the pipe is the same as it should come out, remember that the flow is the product of the cross-sectional area by the flow rate, finally use algebra and input data to Find the exit diameter.
Helium and nitrogen because they are both from the noble gas group.
Answer:
C. Security baggage scanners, because X-rays either pass through or are absorbed by the objects in the baggage, creating an image of the objects
Answer:
1476 J
Explanation:
From the question,
Net Work done = Net force× distance moved by net force.
W' = (F-F')×d................... Equation 1
Where W' = Net work done, F = force applied, F' = Frictional force, d = distance moved.
Given: F = 150 N, F' = 37 N, d = 12 m
Substitute these values into equation 1
W' = (150-37)×12
W' = 123×12
W' = 1476 J.
hence the Net Work done by the object is 1476 J
