Black smokers are hot volcanic vents that emit smoke deep in the ocean floor. Many of them teem with exotic creatures, and some biologists think that life on earth may have begun around such vents. The vents range in depth from about 1500 m to 3200 m below the surface. What is the gauge pressure at a 3200-m deep vent, assuming that the density of water does not vary? Express your answer in Pascal and atmospheres.

Short Answer

Expert verified

Density of water, in Pa =3.23×107Pa

Density of water ,in atm = 320atm

Step by step solution

01

 Step 1: Identification of given value

Lower depth of vent from surface = 1500 m

Upper depth of vent from surface = 3200 m

02

Concept of density

Density is a measure of how densely or loosely a particular material is packed into a given volume.

It is directly proportional to mass and inversely proportional to volume of object.

ÒÏ=mV

03

Determination of density of water in Pa

Pgauge=h×ÒÏ×g=3200m×1030kg/m3×9.81m/s2=3.23×1017Pa

04

Determination of density of water in atm

Pgauge=3.23×107Pa×1latm1.01×105Pa=320.13atm

Thus, density of water in Pa = 3.23×107Pa

Density of water in atm = 320atm

In Wagner’s opera Das Rheingold,the goddess Freia is ransomed for a pile of gold just tall enough and wide enough to hide her from sight. Estimate the monetary value of this pile. The density of gold is 19.3 g/cm3, and take its value to be about $10 per gram.

A cube of oak wood with very smooth faces normally floats in water. Suppose you submerge it completely and press one face flat against the bottom of a tank so that no water is under that face. Will the block float to the surface? Is there a buoyant force on it? Explain.

A Tennis Serve. In the fastest measured tennis serve, the ball left the racquet at 73.14m/s. A served tennis ball is typically in contact with the racquet for30.0and starts from rest. Assume constant acceleration. (a) What was the ball’s acceleration during this serve? (b) How far did the ball travel during the serve?

A hammer with mass m is dropped from rest from a height h above the earth’s surface. This height is not necessarily small compared with the radiusof the earth. Ignoring air resistance, derive an expression for the speed v of the hammer when it reaches the earth’s surface. Your expression should involve h,, and(the earth’s mass).
