A cylindrical tube of length 27.75 cm and radius 2.00 cm is filled with argon gas. The empty tube weighs 188.25 g. The tube filled with argon weighs 188.87 g. Calculate the density. formula =
Answer:
Explanation:
that should help
Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.
How are the density, volume, and mass of a substance related?Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kgdensity of substance = d kg/m³the volume of that substance = v m³Then, they are related as:
d = m/v
The volume of the tube = π × r² × h
= π × (2cm)² × 27.75 cm
= 348.716 cm³
Mass of Argon = Mass when tube is filled - Mass when tube is empty
= 188.87 g - 188.25 g
= 0.62 g
Now, the density of the gas can be written as,
Density = Mass / Volume
= 0.62g / 348.716 cm³
= 1.778 × 10⁻³ gm/cm³
Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.

How do ocean currents affect tempature?
Answer:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate. The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe

What do you think is the primary cause of all-weather patterns, sun, humidity, or air pressure? Support your answer.
Answer:
Temperature is simply a measure of energy present. The heating and cooling of the atmosphere cause currents as cold air moves towards warmer air.
Explanation:
The most basic thing to understand is that warm air wants to rise while cold air wants to sink. Hot air contains fewer molecules per cubic meter while cold air contains more, hence the warm air will rise up over colder air. The most common example of this is the existence of a hot or cold front. These fronts are simply boundaries between hot and cold air.

The picture below shows an experiment to find out the highest frequencies which students can hear. When the teacher turns the dial the frequency from the loudspeaker increases. the students put their hands down when they can no longer hear the sound.
Some students put their hands up while others have put their hands down. What conclusion can you draw from this observation?
The teacher suspects that some of the students are not giving honest responses, they are keeping their hands up even when they can no longer hear the sound. How could he check if he is right? *
Answer: Different hearing abilities.
Explanation:
From the observation, it can be concluded that different students have different hearing abilities. Some students put their hands up later, indicating that they can hear higher frequencies, while others put their hands down earlier, indicating that they can only hear lower frequencies.
To check if the teacher's suspicion about some students not giving honest responses is correct, he could randomly select some students and ask them to identify a few frequencies. He could also use different methods to test their hearing abilities, such as using headphones or playing the sound at different volumes to see if they can still hear it. Additionally, the teacher could repeat the experiment on different days to check if the same students are consistently putting their hands up even when they cannot hear the sound.

Its due tonight so take your time I guess.
Answer:
An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n. Electron shells have one or more electron subshells, or sublevels.
Explanation:
The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6), The 4th shell can hold up to 32 electrons.

Compare the sound of thunder to the sound of a fire alarm at school. How are the wavelengths, frequencies, and amplitudes similar or different?
Answer:
The fire alarm is a higher pitch than thunder.
Explanation:
The fire alarm is a higher pitch so the wavelengths are going to be closer and the amplitude is going to be taller, and the thunder is a lower pitch, so the wavelengths are going to be farther and the amplitude is going to be smaller.
The wavelengths, frequencies, and amplitudes are different for the sound of thunder as compared to the sound of a fire alarm.
Characteristics of sound:The sound of thunder is low pitched sound, whereas the sound of a fire alarm is a high-pitched sound.
The pitch of a sound depends on the frequency of the sound, a higher frequency has a higher pitch. Whereas loudness depends on the amplitude of the sound.
For a low-pitched sound, the slope of the wave on the amplitude and time plot is flatter which means that the wavelength of the sound is larger and the frequency is smaller.
For a high-pitched sound, the slope of the wave on the amplitude and time plot is sharper which means that the wavelength of the sound is smaller and the frequency is larger.

Why can even a small injury to the cornea have a effect on vision
Answer:
It also plays a key role in vision. As light enters your eye, it gets refracted, or bent, by the cornea's curved edge. This helps determine how well your eye can focus on objects close-up and far away. If your cornea is damaged by disease, infection, or an injury, the resulting scars can affect your vision.
