Answer:
C
Explanation:
Because you can feel vibrations through solids but not through gases
Hello.
The formula for Power is Work divided by Time; however, we do not have our value for Work - yet.
To find for the Work inputted, we need to use its formula: Force * Distance.
Let's multiply our Force by our Distance. Remember that our Force is always measured in Newtons (N), and our Distance is measured by Meters (M).
35,000 * 25 = 875,000 J (Unit for Work is "J" or "Joules")
Now that we have the value for Work, let's apply it to our Power formula.
P = 875,000 / 45; 19,444.44~
The Power required to lift the girder is 1944.44~ W (Unit for Power is "W" or "Watts").
I hope this helps!
Answer:
P_v = 31.2 KPa (abs)
Explanation:
-Cavitation may occur in the converging section of the pipe when the pressure equals the vapor pressure of the fluid i.e water.
- From Table B.2 , In Appendix B for water at 70 C we can look up the vapor pressure of the water to be equal:
P_v @70C = 31.2 KPa (abs)
The birth rate would be increasing due to the increasing population. The age structure would therefore be becoming more diverse as more people were being born and most likely immigrating into that population.
