What Daryl said is correct and the relationship among them is a causation than a correlation, because we know that high pitched sound wave has more frequency than that of low pitched sound wave. and we also know that if the medium is same then velocity of wave is same* so if there is high pitched sound wave, it has shorter wavelength and if there's low pitched sound wave it has longer wavelength. since there's an inverse relationship between wavelength and frequency.
I hope it was easy to understand, let me know if you have doubts ~

initial velocity 0 km/hr, final velocity 24km/hr, time 3s, what is acceleration
Answers
Answer:
8 km/hr
Explanation:
Acceleration
=Change in Velocity/ Time
=(24-0)/3
=8
The acceleration of the body is {a} = 8 km/hr².
What is acceleration?Acceleration is defined as the rate of change of velocity per unit time.
Given is -
Initial velocity : 0 km/hr
Final velocity : 24km/hr
Time : 3s
We can write the acceleration as -
a = Δv/Δt
a = (24 - 0)/(3 - 0)
a = 24/3
a = 8 km/hr²
Therefore, the acceleration of the body is {a} = 8 km/hr².

The Earth pulls on the Sun with the same magnitude force that the Sun pulls on the Earth. If these forces are equal, why does Earth go in orbit around the Sun? Why does Earth experience a great centripetal acceleration, while the Sun doesn't?
Answers
Answer:
For every force there is an equal and opposite reaction force.
For instance, if one wants to find the acceleration of a person standing on a scales, he uses the force exerted by the scales on the person,
One doesn't consider the reaction force of the person on the scales.
Likewise for the force of the sun on the earth
m v^2 / R = G M m / R^2 descibes the force acting on the earth to produce the centripetal acceleration of v^2 / R
The sun experiences the same centripetal acceleration as the earth, but since the mass of the sun is about 333,000 times the mass of the earth the acceleration can be ignored for most purposes.
When a satellite experiences an acceleration of v^2 / r, the earth is undergoing the same centripetal acceleration. However since the mass of the earth is much greater than that of a satellite and the centripetal acceleration of the earth is ignored.

What is the reasoning in this passage?
(1 point)
Light can be passed through two slits and projected onto a screen.
The light from the two light sources produces a pattern of dark and light spots on the screen.
The spots are the result of interference, which happens with waves but not particles.
This shows that the wave particle is best for explaining the spots.
Answers
The reasoning in the passage is : ( C ) The spots are the result of interference, which happens with waves but not particles
Light wavesLight passed through a slit and projected onto a screen will form a pattern which is very visible and the pattern might have dark spots if there is some form of interference. Interference is present in waves and not particles.

Part 1 of 3: 2.4 cm³ of water is boiled at atmospheric pressure to become 4514.7 cm³ of steam, also at atmospheric pressure. Calculate the work done by the gas during this process. The latent heat of vaporization of water is 2.26 × 10⁶ J/kg. Answer in units of J.
Part 2 of 3: Find the amount of heat added to the water to accomplish this process. Answer in units of J.
Part 3 of 3: Find the change in internal energy. Answer in units of J.
Answers
During the isobaric expansion;
work done by the gas is 457.2 Jheat absorbed by the water is 4520 Jthe change in internal energy of a system is 4062.8 J.What is the work done by a gas in an isolated process?The work done by a gas in an isolated expansion is the product of pressure and change in volume.
[tex]W = p\times \Delta V[/tex]
1 atm = 101325 Pa
2.4 cm³ = 2.4 × 10^-6 m³
4514.7 cm³ = 4514.7 × 10^-6 m³
[tex]W = 101325 Pa \times (4514.7\times 10^{-6} m^3 - 2.4\times10^{-6} m^3) = 457.2 J \\ [/tex]
Thus, work done by the gas is 457.2 J
Tje Heat absorbed by the water during vaporization process is calculated using the formul:
Q = m×ΔHvapmass of water = density × volume
mass of water = 1 g/cm³ × 2.4 cm³ = 2 g = 0.002 kg
Q = 0.002 kg × 2.26 × 10⁶ J/kg
Q = 4520 J
Thus, heat absorbed by the water is 4520 J
The change in internal energy, ΔU of a system is given as the heat absorbed minus the work done by the system.
[tex]\Delta U = Q-W [/tex]
ΔU = 4520 J − 457.2 J = 4062.8 J
Therefore, the change in internal energy of a system is 4062.8 J.

A block is sitting on a small platform supported by a spring and is undergoing simple harmonic oscillation with a frequency of 4.5 Hz. What is the maximum amplitude at which the block will stay on the platform
Answers
For a block undergoing simple harmonic oscillation, the maximum amplitude is mathematically given as
a=0.0749m
Generally, the equation for the maximum acceleration is mathematically given as

Therefore
0.075 * w^2 = 9.8
w = 11.43 rad/s
In conclusion, maximum frequency

Answers
As the slit width increases, the diffraction pattern gets narrower and vice versa.
Relationship between width and diffraction patternThe increase in silt width leads to the narrowing of diffraction pattern of the light because the increase of width reduces the space for the passing of light wave.
