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.

All of the above.

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.

The phases where surfer’s most likely benefit include D. 1st Quarter and 3rd Quarter.

Surfers will benefit include during the 1st Quarter and 3rd Quarter because there's tidal change. Tidal change is when coastal areas experience two low and high tides.

The benefit of surfing during this period is that it helps jack the waves. Waves transmit energy and this is important to surfers.

Explanation:

The angle of refraction is 3

The correct option is 3.

The angle formed at the point of incidence between the incident ray and the normal is called the angle of incidence. The angle formed between the refracted ray and the normal is called the angle of refraction. The angle of Incidence and Angle of Refraction.

As in reflection, we measure the angles from the normal to the surface, at the point of contact. The constants n are the indices of refraction for the corresponding media.

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.

"When two waves of identical wavelength are in phase, they form a new wave with an amplitude equal to the sum of their individual amplitudes."

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.
