Water has a density that is 13.6 times less than that of mercury. if an undersea vessel descends to 1.6 km, how much pressure does the water exert in atm?

155.25 atm

Explanation:

Distance, h = 1.6 km = 1600 m

density of water = 13.6 times less than the density of mercury

density of mercury = 13.6 x 10^3 kg/m^3

So, density of water = 1 x 10^3 kg/m^3

Pressure exerted by the water

P = distance x density of water x acceleration due to gravity

P = 1600 x 1000 x 9.8

We know that

1 atm = 1.01 x 10^5 Pa

So, =

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
