Answer:
Momentum, p = 7.2 g-m/s
Explanation:
It is given that,
The momentum of an object is 
We need to express momentum in any equivalent units. There can be many solutions of this problem. Some of the units of mass are gram, milligram etc. units of length are meters, mm etc.
Since, 1 kg = 1000 gram
So, 
Therefore, the momentum of the object is 7.2 g-m/s. Hence, this is the required solution.
Answer:
Question one is b, Question two is b, and question three is b, im pretty positive that what it is
No, resolve in both directions separately
The density would decrease because the mass of an object deals with the amount of atoms in the object and since none of the object was reduced "a" wouldn't be the answer. Depending on the amount and period of time that the heat is applied the liquid could change into a gas so "d" wouldn't be correct. Density is the mass÷ volume, and when you add heat to an object it could take up different amounts of space because of its particles gaining energy and spreading apart. So the density would decrease because of the volume increasing. So I believe that "c" is the answer.
