Coulomb's law applies to all charges. It doesn't care what the specific
purpose of the individual charge may be at the moment.
-Positively charged nucleus
-Empty spaced
-Dense core
Answer:
yes
Explanation:
its not a good thing for the rest of your life but you have a PS4
Answer:
-39.2m/s
Explanation:
Using the equation of motion;
v = u + at
Since the ball is thrown upward, the acceleration due to gravity acting on it will be negative, hence a = -g
v = u - gt
Since g = 9.8m/s²
t = 4.0s
u = 0m/s
v = 0 + (-9.8)(4)
v = 0 + (-9.8)(4)
v = -39.2m/s
Hence the speed of the ball before release is -39.2m/s
Gravity pulls every part of the body to make it equal distance to all surfaces <span />
