Explain how you can measure the wavelength and amplitude of a wave on paper.
Please help quickly!!!!!
Answer:
The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, a wavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.
Explanation:
Wavelength is defined as the distance between the two crests or shape repeats of the wave. The amplitude of the wave is defined as the maximum displacement of a particle from rest to trough position.
The wavelength is the distance between two successive troughs or crests of the waves.
The formula for measuring the wavelength is:
[tex]\lambda} &= \dfrac {v}{f}[/tex]
where,
[tex]\lambda[/tex] = wavelength
v = velocity
f = frequency
Also, the distance between either two crests or two troughs can also determine the wavelength.
Now, to calculate the amplitude, which is the maximum displacement of a particle in rest position is:
y(x,t) = A sin (kx−ωt+ϕ)
where,
A = amplitude, ω= angular velocity, and t is time.
Also, the measurement of a height from highest to lowest points in a wave and then divided by 2 can give the value of amplitude.

How could you mitigate the risk of transporting
fuel to the power plant?
Mitigate the risk of transporting fuel to the power plant must supplant old gadgets by energy productive arrangements, like supplanting conventional lights.
What is a Power plant?Power plants convert crude energy sources like coal, atomic intensity, or wind, into usable power that was converse the energy. A nuclear energy station, which is perhaps the most well-known type, is a plant that makes power by consuming fuel to change over it into power.
Making minimized urban communities that decrease distances to public vehicles, increment land thickness, and increment land use variety can get individuals out of confidential vehicles and onto mass travel.

Explanation:
1.The woolly mammoth is a relative to the elephant and can be found in the tundra steppe also known as mammoth steppe. Its tusks are so valuable because traders can sell them for 400 in yakutsk and also they are rare to find.
2. The mammoths' remains are so easy to find because during the time they were found, we had already had tools find it but not really advanced. They are so easy because according to scientists the woolly mammoths are so large and bones were long. According to research, it is said for the mammoths to have gone extinct 30,000 years ago and were found by humans 15,000 years ago. Now, they are kept in preserves for safe keeping.
3. The extinction presents a problem because they were so strong and would have protected us humans from non passive creatures. So, in ways they have would have been useful.
