Answer:
The value 
Explanation:
From the question we are told that
The acceleration due to gravity is a = 2g
The maximum height is h= 39 m
Generally from the kinematic equation

Here u is the velocity of the ball at maximum height before it start falling and the value is 0 m/s
So




It seems that you have missed the necessary options for us to answer this question so I had to look for it. Anyway, here is the answer. The statement that is correct regarding the polarization of a neuronal membrane and the formation of a resting membrane potential is this: <span>Sodium/Potassium pumps maintain concentration gradients; sodium and potassium move down their concentration gradients through leakage channels.</span>
Fg=m•g || IE: Weight = mass x gravity
Therefore, the relationship are as follows:
mass and gravity are inversely proportional
mass and weight are directly proportional
weight and gravity are directly proportional
The answer is false. The Milky Way Galaxy is known to be
1,000,000,000,000,000,000 kilometers which is about 100,000 lightyears across,
which states that the Sun do not lie near the center of our galaxy, since the
sun’s radius is six hundred ninety-five thousand seven hundred (695,700)
kilometers, wherein it is 999,999,999,999,304,300 kilometers difference from
the Milky Way Galaxy’s radius.
