Answer:
Yes, the value of g affected by the radius.
Explanation:
The formula for the force of gravity of 2 objects is
, where m1 and m2 are the masses of the 2 objects, r is the radius, and G is the gravitational constant, which is approximately .
Therefore, as the radius if bigger, the force of gravity is going to be smaller exponentially.
Answer:
Endothermic reaction
Explanation:
If the reaction releases less energy than the energy needed to start the chemical reaction, then the reaction takes energy from the system. An endothermic reaction is a reaction that will takes energy from the system. Those energies will be put into the product of the reaction, make the product have higher potential energy than the reactant. The product of this reactant will be less stable since it's at a high energy state.

Answer:
Current
Explanation:
The equation you mentioned is also known as Ohm's law, which can be applied for any circuit containing a battery and one (or more) resistors:
where
V is the voltage
I is the current
R is the resistance
We can re-arrange the equation and rewrite it explicitely for I, the current, to match the equation mentioned in the text of the question, and we have:
