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.

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.

Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.

Suppose that a finite amount of substance is there having its properties as:

Then, 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.

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.

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

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.

Answer:

Explanation:

1. brain, senses

2. instincts, senses

3. interpreted

4. reflexes, organs

The central nervous system includes the brain and spinal cord.

Signals from senses and the body's organs are received by the brain and the spinal cord.

Once signals are processed and interpreted by the central nervous system, a response is sent back to the body.

A central nervous system is also responsible for programming reflexes and instincts.

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.

And the pros are just don't do it, actual help is hard to find but like if you were to try and start over you could possibly also don't do that to who ever has to clean up the bloody mess. Coroners don't like getting hung bodies down and janitors don't like cleaning up blood. :) Find someone who loves you more than you do for yourself that will help a lot. Find a thing you like doing it helps too. Disappear for a day or two.
