Acceleration due to gravity will be constant, but the speed can change.
Answer:
<h2>1 st statement is correct </h2>
Explanation:
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it's added from the outside

Answer:
(3) The electrons are attracted to the positively charged nucleus.
(4) Positively charged protons are located in the tiny, massive nucleus.
(6) The negatively charged electrons are spread out in a "cloud" around the nucleus.
Explanation:
An atom is the basic particle in which a matter is formed. It can either be charged or neutral. When it losses or gains an extra electron, it becomes charged, an ion. While a neutral atom is an atom which has no charge, because it has the same number of electrons and protons. The protons are located in the tiny massive nucleus of the atom, while the electrons are in orbits or cloud around the nucleus.
gravitational potential is given as
![V = \frac{GM}{R^2}(R^2 + Z^2)^0.5](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7BGM%7D%7BR%5E2%7D%28R%5E2%20%2B%20Z%5E2%29%5E0.5)
![E = -\frac{dV}{dz}](https://tex.z-dn.net/?f=E%20%3D%20-%5Cfrac%7BdV%7D%7Bdz%7D)
![E = -\frac{GM}{R^2}\frac{d}{dz}(R^2+z^2)^0.5](https://tex.z-dn.net/?f=E%20%3D%20-%5Cfrac%7BGM%7D%7BR%5E2%7D%5Cfrac%7Bd%7D%7Bdz%7D%28R%5E2%2Bz%5E2%29%5E0.5)
![E = -\frac{GM*z}{R^2*(R^2 + z^2)^0.5}](https://tex.z-dn.net/?f=E%20%3D%20-%5Cfrac%7BGM%2Az%7D%7BR%5E2%2A%28R%5E2%20%2B%20z%5E2%29%5E0.5%7D)
now plug in all values given
M = 110 kg
R = 0.55 m
z = 0.17 m
![E = -\frac{6.67 * 10^{-11}* 110*0.17}{0.55^2*(0.55^2 + 0.17^2)^0.5}](https://tex.z-dn.net/?f=E%20%3D%20-%5Cfrac%7B6.67%20%2A%2010%5E%7B-11%7D%2A%20110%2A0.17%7D%7B0.55%5E2%2A%280.55%5E2%20%2B%200.17%5E2%29%5E0.5%7D)
![E = 7.16 * 10^{-9} N/kg](https://tex.z-dn.net/?f=E%20%3D%207.16%20%2A%2010%5E%7B-9%7D%20N%2Fkg)
so above is the field intensity
