Your mass can never change no matter where you are since mass is the amount of matter you contain. By going to the moon, you do become lighter due to the weaker gravity but the amount of matter that you are made of (your mass) does not change.
I hope the helps. Let me know if anything is unclear.
Answer:
Explanation:
The substances that are present at the beginning are called reactants and the substances present at the end are called products. Sometimes when reactants are put into a reaction vessel, a reaction will take place to produce products.

It's #1, a helium nucleus.
Answer : The density of the block is estimated to be, .
Explanation :
Density of the water,
As we know that,
Buoyant force =
where,
g = gravitational acceleration
volume of the block = v
density of the block =
Weight of the Block = Buoyant force exerted by water
Thus, the density of the block is estimated to be, .
