B. Law of ellipses.
which states that the path of planets about the Sun is in Elliptical shape (hence the name).
Electric field due to a point charge is given as

here we know that

also the distance is given as

now we will have

so we will have

so above is the electric field due to proton
In terms of the scientific method, the immediate purpose of doing an experiment is gathering data. You cannot draw conclusions or form a proper hypothesis without some sort of basis and data.
Answer:
It is due to the large impulse is imparted on the flour.
Explanation:
A ball is moving faster.
When a ball is moving faster strikes to the flour, the change in momentum is large and thus the impulse imparted on the flour is large.
Impulse = change in momentum
So, as the flour experiences large impulse and large momentum so that the flour spreads out.
If the change in momentum is large so the flour spreads out is more.
