I think its inductance. If its not then I think its none of the above
Answer:
Max speed = ![\frac{15\, \pi}{4} \,\, \frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7B15%5C%2C%20%5Cpi%7D%7B4%7D%20%5C%2C%5C%2C%20%5Cfrac%7Bm%7D%7Bs%7D)
Max acceleration = ![\frac{15\,\pi^2}{16} \,\,\frac{m}{s^2}](https://tex.z-dn.net/?f=%5Cfrac%7B15%5C%2C%5Cpi%5E2%7D%7B16%7D%20%5C%2C%5C%2C%5Cfrac%7Bm%7D%7Bs%5E2%7D)
Explanation:
Given the description of period and amplitude, the SHM could be described by:
![f(x)=5\,sin(\frac{\pi}{4}x)](https://tex.z-dn.net/?f=f%28x%29%3D5%5C%2Csin%28%5Cfrac%7B%5Cpi%7D%7B4%7Dx%29)
and its angular velocity can be calculated doing the derivative:
![f(x)=5\, \,sin(\frac{\pi}{4}x)\\f'(x)=5\,\frac{\pi}{4}\,cos(\frac{\pi}{4}x)](https://tex.z-dn.net/?f=f%28x%29%3D5%5C%2C%20%5C%2Csin%28%5Cfrac%7B%5Cpi%7D%7B4%7Dx%29%5C%5Cf%27%28x%29%3D5%5C%2C%5Cfrac%7B%5Cpi%7D%7B4%7D%5C%2Ccos%28%5Cfrac%7B%5Cpi%7D%7B4%7Dx%29)
And therefore, the tangential velocity is calculated by multiplying this expression times the radius of the movement (3 m):
and is given in m/s.
Then the maximum speed is obtained when the cosine function becomes "1", and that gives:
Max speed = ![\frac{15\, \pi}{4} \,\, \frac{m}{s}](https://tex.z-dn.net/?f=%5Cfrac%7B15%5C%2C%20%5Cpi%7D%7B4%7D%20%5C%2C%5C%2C%20%5Cfrac%7Bm%7D%7Bs%7D)
The acceleration is found from the derivative of the velocity expression, and therefore given by:
![acceleraton(x)=-15\,\frac{\pi^2}{16}\,sin(\frac{\pi}{4}x)](https://tex.z-dn.net/?f=acceleraton%28x%29%3D-15%5C%2C%5Cfrac%7B%5Cpi%5E2%7D%7B16%7D%5C%2Csin%28%5Cfrac%7B%5Cpi%7D%7B4%7Dx%29)
and the maximum of the function will be obtained when the sine expression becomes "-1", which will render:
Max acceleration = ![\frac{15\,\pi^2}{16} \,\,\frac{m}{s^2}](https://tex.z-dn.net/?f=%5Cfrac%7B15%5C%2C%5Cpi%5E2%7D%7B16%7D%20%5C%2C%5C%2C%5Cfrac%7Bm%7D%7Bs%5E2%7D)
Answer:
Shadows are made by blocking light. Light rays travel from a source in straight lines. If an opaque (solid) object gets in the way, it stops light rays from traveling through it. The size and shape of a shadow depend on the position and size of the light source compared to the object.
Explanation:
Competition in the Los Angeles Flower District results in better quality flowers.
<h3>Why quality is the standard in flower competition?</h3>
Competition results in better quality flowers because in the competition, best quality of flowers will be selected as a winner so the competitors produces best quality of flowers in order to claim the prize so we can conclude that Competition in the Los Angeles Flower District results in better quality flowers

Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance
