The force between two charges objects is related to separation.
As per momentum conservation we can say that Chuck and ball as a system has no external force
So here momentum of them must be conserved
now here initially if they are at rest
so we can say
now we have
now the relative velocity of the cart and ball is given as
also we can say since they are moving in opposite direction so relative speed will be
Explanation:
Below is an attachment containing the solution.
22 year solar cycle is characterized by a variation in the number of sunspots and a reversal of the polarity of the Sun as a whole.
What are sunspots?
Sunspots are caused by disturbances in the Sun's magnetic field welling up to the Sun's visible surface.
Sunspot are region of the earth that are more darker than other surfaces. They have a reduced temperature.
If sunspots are active, more solar flares will result creating an increase in geomagnetic storm activity for Earth.
Here, the sun's magnetic field changes polarity approximately every 11 years. So, for reversal polarity of the sun, 22 year solar cycle is characterized by a variation in the number of sunspots and a reversal of the polarity of the Sun as a whole.

We have millions of alveoli under our lungs, they diffuse oxygen molecules in our blood, then they get transported to every organ of our body through our Heart
Hope this helps!
