B and C because an earthquake does not directly affect gravity, and precipitation doesn’t fall, it is water surfacing
Answer:
The mass is 1200 kilograms
Explanation:
Because Force is equal to mass times acceleration (F=m×a)
F=m×a
1800N=?×1.5
1800÷1.5=1200
1800N=1200Kg×1.5
Answer:
No, the mass of an object is always the same, even if a chemical reaction happens or the object becomes denser.
