Answer: a) 112.88 * 10^3 N/C; b) The electric field point outward from the center of the sphere.
Explanation: In order to solve this problem we have to use the gaussian law so we use a gaussian surface at r=0.965 m and the electric flux is equal to Q inside/εo
E* 4*π*r^2= Q inside/εo
E= k*Q inside/r^2= 9*10^9*(6.53+5.15)μC/(0.965)^2=122.88 * 10 ^3 N/C

Explanation:
v=28.2, a=9.81
start from rest u=0
v=u+at=0+(9.81)t=28.2
t=2.875...
it reach 1.4 second before hitting the ground:
t=1.4, u=0, a=9.81
v=u+at=0+(9.81)(1.4)=12.74
I have the sender immediately notify me about this one and only the one you are interested please send us your requirements with you on this site for a few months ago but have not heard back yet over to you as soon and will have to get a new one is the same as last time I have to do it is not an intended solely those are the best way for me to get a good day.
gravitational Potential energy is given by

here we have
m = 200 kg
h = 21000 m
now we will have


so GPE of balloon will be 41160000 J above the given height from ground
almost everything artafitial would have been made because of science. However nothing natural would exist because of science. All science does is look around and see what's up.
