Something to do with how the suns magnetic field interacts with the surface plasmas I think.
Answer:
I think the answer is C.
Explanation:
A primary source is a first hand account of an event while a secondary source is a retelling or second hand account meaning as many details will be prevalent.
Answer:
<em>v=40 m/s south</em>
Explanation:
<u>Momentum
</u>
It's a physical magnitude that measures the product of the mass by the velocity of a particle. Its units in the International System is kg.m/s and the formula is
![p=m.v](https://tex.z-dn.net/?f=p%3Dm.v)
Where m is the mass and v the velocity of the particle. If we wanted to solve for v, we have
![\displaystyle v=\frac{p}{m}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v%3D%5Cfrac%7Bp%7D%7Bm%7D)
The baseball has a momentum of 6.0 kg.m/s south and mass of 0.15kg, thus
![\displaystyle v=\frac{6}{0.15}=40\ m/s](https://tex.z-dn.net/?f=%5Cdisplaystyle%20v%3D%5Cfrac%7B6%7D%7B0.15%7D%3D40%5C%20m%2Fs)
The velocity is directed to the south
It's very hard to see the self-portrait, so I can't identify him.
