Answer and Explanation:
The charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
Normally, the charge on such spherical surface stay on this surface uniformly, but the presence of a voltage source tampers with that dynamic.
The constants could be the day because the experiment is all on the same day or the person throwing the pumpkin because it will always be the same perosn
Answer:
16.25 m
Explanation:
we know that the equation pf parabola

from bellow figure the coordinate of parabola is (600,65) that is y=600 and x=65
putting the the value of y and x in the equation of parabola

k=0.0001805
now the equation is

we have to find the value of y at x=300m
so 
y=16.25 m
