B is the correct answer

As SCUBA divers go deeper underwater, the pressure from the weight of all the water above them increases tremendously which compresses the gases in their blood. What happens to the volume of gas in their blood as the diver rises quickly to the surface?



A.
As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.

D.
As a diver rises, the pressure on their body increases which allows the volume of the gas to increase.

Answers

Answer: A.

As a diver rises, the pressure on their body decreases which allows the volume of the gas to decrease.

Explanation:

The problem is that a diver, experiences an increased pressure of water compresses nitrogen and more of it dissolves into the body. Just as there is a natural nitrogen saturation point at the surface, there are saturation points under water. Those depend on the depth, the type of body tissue involved, and also how long a diver is exposed to the extra pressure. The deeper a diver go, the more nitrogen the body absorbs.

The problem is getting rid of the nitrogen once you ascend again. As the pressure diminishes, nitrogen starts dissolving out of the tissues of the diver's body, a process called "off-gassing." That results in tiny nitrogen bubbles that then get carried to the lungs and breathed out. However, if there is too much nitrogen and/or it is released too quickly, small bubbles can combine to form larger bubbles, and those can do damage to the body, anything from minor discomforts all the way to major problems and even death.

A 5.00 cm tall object is placed 4.25 cm from a lens and produces an image that is 3.00 cm behind the lens. What is the magnification of the lens?

Answers

Answer:

The magnification of the lens is 0.7

Explanation:

We have,

Height of an object is 5 cm

Object is placed 4.25 cm from a lens

Image is formed 3.00 cm behind the lens.

It means u = -4.25 cm

v = -3 cm (behind the lens)

Magnification of the lens is given by :

[tex]m=\dfrac{v}{u}\\\\m=\dfrac{-3}{-4.25}\\\\m=0.70[/tex]

What is the resistance of a 6.0 m long gold wire (ρgold = 5.6 x 10 -8 Ω-m) whose cross-sectional area is 5x10 -7m 2 ? (Please show some work)

Answers

Answer:

R =0.672 ohms

Explanation:

We have,

Length of a gold wire is 6 m

Resistivity of gold is [tex]5.6\times 10^{-8}\ \Omega-m[/tex]

Area of cross section of the wire is [tex]5\times 10^{-7}\ m^2[/tex]

The resistance of a wire is given by the relation as follows :

[tex]R=\rho\dfrac{l}{A}\\\\R=5.6\times 10^{-8}\times \dfrac{6}{5\times 10^{-7}}\\\\R=0.672\ \Omega[/tex]

So, the resistance of the gold wire is 0.672 ohms.

In a science experiment showing the splitting of water into Oxygen and hydrogen, two inverted test tubes of water were placed over the site of the reaction. (see the pic) How can you tell which one was catching the oxygen and which one was catching the hydrogen? Question 4 options: The hydrogen is a positive ion and will be located close to the negative terminal of the battery. The oxygen is a negative ion which will be located next to the negative terminal of the battery. There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube. The hydrogen, being a smaller atom, will take up less space than the oxygen. It will push the water down less.

Answers

Answer:

There are 2 hydrogen atoms for every oxygen atom. The hydrogen will take up more space and is pushing the water lower in the test tube.

Explanation:

To find out what water is made of, we may have to look at its chemical formula, which is H2O. This basically tells us that the water molecule is composed of two elements: hydrogen and oxygen or, more precisely, two hydrogen atoms (H2) and one oxygen atom (O). Hydrogen and oxygen are gases at room temperature. Splitting water into its two components is much easier to do by a process called water electrolysis. Making hydrogen or oxygen this way seems simple. In water electrolysis, the source of energy used is electricity. An easy way to generate electricity is with a battery. Because pure water is not good at conducting electricity, however, electrolysis requires the addition of an electrolyte, such as salt or acid. The electrolyte dissolves in water and separates into ions (electrically charged particles) that move through the solutions and are able to conduct electricity this way.

As electrolysis progresses, the water level at the negative terminal becomes about half that of the positive terminal, meaning that we have collected double the amount of hydrogen gas compared with oxygen. The difference is due to the fact that one water molecule has two hydrogen atoms to one oxygen atom, as explained above. This means it takes two water molecules (2 H2O) to make one oxygen molecule (O2). At the same time, however, two molecules of water (2 H2O) can make two molecules of hydrogen (2 H2). Hence the answer.

Do waves transfer matter?

Answers

Answer: Light energy only travels through empty space absent of mass energy and kinetic energy only travels through a medium full of mass energy. ... Waves don't transfer mass because mass is not the same as a wave. Mass can hold “extra” energy but it is that energy that moves through it as a wave, not the particle itself.

In a wave phenomenon, energy can move from one location to another, yet the particles of matter in the medium return to their fixed position. A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position.

Two identical speakers are 3.50 m and 5.20 m from a listener. What is the lowest frequency (n = 1) that would cause constructive interference there? PLS HELP!

Answers

For constructive interference the path difference must be an integer number of wavelengths. The lowest frequency for this would be the longest wavelength with the path difference equal to one wavelength.

Path length difference(m) = 5.20 - 3.50 = 1.70m.

λ =2m ⇒ f = v/λ

λ/2 =1.70

λ = 3.40m

Taking speed of sound as v = 340m/s:

f = v/λ = 340/3.40 = 100Hz.
