The force of friction is given by:
f = μR, where μ is the friction coefficient and R is the reaction force, which will be equal to the weight.
100 = μ x 130
μ = 0.77
Answer:
Power will be 0.2023 watt
And when amplitude is halved then power will be 0.0505 watt
Explanation:
We have given mass of the Piano wire m = 2.60 gram = 0.0026 kg
Length of wire l = 84 cm = 0.84 m
So mass density ![\mu =\frac{m}{l}=\frac{0.0026}{0.84}=0.0031kg/m](https://tex.z-dn.net/?f=%5Cmu%20%3D%5Cfrac%7Bm%7D%7Bl%7D%3D%5Cfrac%7B0.0026%7D%7B0.84%7D%3D0.0031kg%2Fm)
Tension in the wire T = 25 N
Frequency f = 120 Hz
So angular frequency ![\omega =2\pi f=2\times 3.14\times 120=753.6rad/sec](https://tex.z-dn.net/?f=%5Comega%20%3D2%5Cpi%20f%3D2%5Ctimes%203.14%5Ctimes%20120%3D753.6rad%2Fsec)
And amplitude A = 1.6 mm = 0.0016 m
We have to find the generated power
Power is given by ![P=\frac{1}{2}\sqrt{\mu T}\omega ^2A^2=\frac{1}{2}\times \sqrt{0.0031\times 25}\times 753.6^2\times 0.0016^2=0.2023watt](https://tex.z-dn.net/?f=P%3D%5Cfrac%7B1%7D%7B2%7D%5Csqrt%7B%5Cmu%20T%7D%5Comega%20%5E2A%5E2%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5Csqrt%7B0.0031%5Ctimes%2025%7D%5Ctimes%20753.6%5E2%5Ctimes%200.0016%5E2%3D0.2023watt)
From the relation we can see that power ![P\ \propto\ A^2](https://tex.z-dn.net/?f=P%5C%20%5Cpropto%5C%20A%5E2)
So if amplitude is halved then power will be
times
So power will be equal to ![\frac{0.2023}{2}=0.0505watt](https://tex.z-dn.net/?f=%5Cfrac%7B0.2023%7D%7B2%7D%3D0.0505watt)
How does the different type of music such as classic, hiphop, or rock affect the human mind
Answer: See the explanation below.
Explanation: For this assignment, I chose to display how eclipses are created.
My model was made utilizing a 3D displaying device program for all intents and purposes. The items utilized are three models I made for this presentation, Earth, the moon, and the sun. These three models will be utilized for the showcase.
The light that shines from the sun would create a shadow on the moon. The moon would then catch the light that should've arrived on Earth, making the shadow we call an eclipse. Earth gets a shadow of the moon and the remainder of Earth is lit up from the rest of the light, making an eclipse.
The individual I demonstrated my project to was [<em>Someone you know</em>], [<em>Pronoun</em>] said it precisely took after the occasion of an eclipse. The light from the sun being shined on to the moon rather than the Earth, creating the shadow we call an eclipse.
