Astring that is 3.6 m long is tied between two posts and plucked. the string produces a wave that has a frequency of 320 hz and travels with a speed of 192 m/s. how many full wavelengths of the wave fit on the string?

To solve this problem it is necessary to apply the concepts related to wavelength depending on the frequency and speed. Mathematically, the wavelength can be expressed as

Where,

v = Velocity

f = Frequency,

Our values are given as

L = 3.6m

v= 192m/s

f= 320Hz

Replacing we have that

The total number of 'wavelengths' that will be in the string will be subject to the total length over the size of each of these undulations, that is,

Therefore the number of wavelengths of the wave fit on the string is 6.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
