Answer:
Gravitational force is also decreases.
Explanation:
Gravitational force is directly proportional to the mass of an object and inversely properly to the distance between their centres. Directly means if one increases the other automatically increases or if one decreases, the other also decreases. There is a direct relationship between mass and gravitational force so if mass of the bodies decrease, the gravitational force is also decreases.
Answer:The correct answer is option 4.
Explanation:
Arrhenius acids are those compounds which gives 
ions when dissolved in their aqueous solution.
Arrhenius bases are those compounds which gives 
ions when dissolved in their aqueous solution.
are Arrhenius acids because they form ions in their respective aqueous solution.
Hence, the correct answer is option 4.
