Question
her older brother weighing 125 1BS SIL 1W DliaI 2 Crush Depth. One atmosphere is about 15 psi. Every time you go down 10 meters in depth into the ocean add 1 more atmosphere of pressure. You want to visit the Mariana Trench (about 10,990 meters). What pressures will your submarine have to withstand? bottom of the 3 Athletic Horsepower. Last year a female runner set a record running up the 86 flights (1576 steps; 1050 vertical feet) of the Empire State building in 9 minutes 33 seconds. Let's assume she weighs 100 pounds. How much work did she do? What was her average horsepower? 4 Nuclear Power. Somehow you are able to convert all the energy in 1 teaspoon of water (5 mL) into electrical power. Your home uses an average of 3 KiloWatts of power. How long will that water supply power to your home?Explanation / Answer
2) crush depth :
Mariana trench is about at 10,990m
Now we have given that the in 10m depth will addition of 1 atmospheric pressure.
Hence at 10,990m there will be---- 1099 atmospheric pressure.
This much pressure will your submarine have to withstand.
3) work = force x (distance)
= mass x acceleration due to gravity x (distance)
(100 pound = 45.3592 kg)
(1576 steps is normally 0.788 miles = 1.2681 km = 1268 m) )
= 45.3592 kg x 9.8 m/s2 x 1268 m
= 563651.563 kg m2/ s2
= 563651. 563 Joule
Average horsepower(HP) = (mass x 9.81 x height)/ t
= 100 pound x 32.1768 ft/ s2 x 1050 ft) / 573 sec
= 5896.27 ft-lb/s
4) suppose for 1 teaspoon of water creates 1 watt energy then for 3 kilowatt = 3000watt, how much teaspoon required
Do cross multiply, you will get 3000teaspoon required which is 15000ml of water.
