Inertia is what keeps everything moving, so if it didn't exist, the balls wouldn't keep going when they are kicked, or thrown.
A. is the answer for this question
By putting this special transportation plastic on the bottom of the sled, because the transportation plastic is slick. that is what the transport bins slide around on. (p.s) the plastic is really expensive!
Explanation:
The general equation of an AC current is given by :
![I=I_o sin\omega t](https://tex.z-dn.net/?f=I%3DI_o%20sin%5Comega%20t)
Where
I₀ is the peak value of current
is angular frequency
![As\ \omega=2\pi f](https://tex.z-dn.net/?f=As%5C%20%5Comega%3D2%5Cpi%20f)
So,
![f=\dfrac{\omega}{2\pi}\\\\f=\dfrac{100\pi}{2\pi}\\\\f=50\ Hz](https://tex.z-dn.net/?f=f%3D%5Cdfrac%7B%5Comega%7D%7B2%5Cpi%7D%5C%5C%5C%5Cf%3D%5Cdfrac%7B100%5Cpi%7D%7B2%5Cpi%7D%5C%5C%5C%5Cf%3D50%5C%20Hz)
We know that,
![I_{rms}=\dfrac{I_0}{\sqrt{2}}\\\\=\dfrac{20}{\sqrt{2}}\\\\I_{rms}=14.14\ A](https://tex.z-dn.net/?f=I_%7Brms%7D%3D%5Cdfrac%7BI_0%7D%7B%5Csqrt%7B2%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B20%7D%7B%5Csqrt%7B2%7D%7D%5C%5C%5C%5CI_%7Brms%7D%3D14.14%5C%20A)
So, the frequency is 50 Hz and the maximum rms value of current is 14.14 A.
