Black smokers are hot volcanic vents that emit smoke deep in the ocean floor. Many of them teem with exotic creatures, and some

erica [24]

If the density of water does not vary and the vents range in depth from about 1500 m to 3200 m below the surface, then the gauge pressure at a 2452-m deep vent is 224.268 atm.

Calculation:

Step-1:

It is given that the vents range in depth from about 1500 m to 3200 m below the surface. If we are assuming that the density of water does not vary. Then it is required to calculate the gauge pressure at a 2452-m deep vent.

The gauge pressure at a particular depth of ocean water is calculated as:

$P=\rho g h$

Here $\rho$ is the density of water, P is the required pressure, h is the depth of water, and g is the gravitational acceleration.

Step-2:

Now we are substituting the values to calculate the pressure at the depth of 2452-m.

$\\\begin{aligned}\\P&=\rho gh\\&=1030 (\text{ kg/m}^3)\times 9.8 (\text{ m/s}^2)\times 2452 \text{ m}\\&=24.75\times 10^6 \text{ Pa}\times\frac{1 \text{ atm}}{10.1325 \times10^4 \text{ Pa}}\\&=224.268 \text{ atm}\\\end{aligned}\\$

The start of the Space Age throughout the 1950s and 1960s helped Florida's economy flourish. How did it continue to impact Flori

Inessa05 [86]

Answer:

A) After the Space Age ended, many people moved to other states and the economy began to decline.

Explanation:

After the space age ended, businesses slumped, when the space shuttle program ended those made redundant could not be re absorbed due to a lack of follow-on by NASA. The 2008 recession also had impacted businesses in the area. As such many moved to other states, which had the effect of a brain drain.

After Apollo, in the late 70's, there was a similar decline of economic activities as workers were laid off and where finding it hard to sell off their properties as the real estate prices where low.

At an outdoor market, a bunch of bananas is set on a spring scale to measure the weight. The spring sets the full bunch of banan

olga55 [171]

Answer:

Mass of banana is $1.12$ Kg

Explanation:

Step 1: Determine the equation of speed of an object moving in an harmonic motion

Speed of moving in an harmonic motion is given by

$v = \sqrt{\frac{k}{m} (A^2 -x^2)} \\$

Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.

In this question , $x = 0$ because only at this position maximum speed occurs

So the simplified equation becomes -

$v = \sqrt{(\frac{k}{m} * A)}$

OR

$m = \frac{kA^2}{v_(max)^2}$

Substituting the given values in above equation we get -

Assume spring constant is $16$ N/m

$m = \frac{16 * 0.14}{2} \\m = 1.12$

Mass of banana is $1.12$ Kg

astraxan [27]

Answer:

It is possible to statically charge objects by rubbing it against carpet fibers, but I'm not sure if that was in the article that you read.

Explanation:

Static charge can build up via carpet fibers.
