Answer 1

Answer:

In physics and chemistry, the law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Answer 2

Step-by-step explanation:

here 100000 cm = 1cm (given)

12/3 = 12/3 × 100000 = 400000 cm = 400 m = 0.4 km
