Distance is a scalar and measured only by units (meters, feet). Position is a vector and depends on where the origin is. It can be negative or positive and has direction.
Closed
Explanation:
A physical system that is isolated from its environment is said to be a closed system.
In a closed system, energy can be exchange but matter cannot be exchanged.
- A closed system sightly permits the only certain types of exchange.
- These systems are usually used to control and limit the impact of the environment on a system.
- Experiments can be conducted on the premises of any the interactions.

Answer:
The bottom of the sea is 25 m below sea level.
Explanation:
Given data
Mass = 6.1 × 
We know that Buoyant force on the tank is equal to gravity force of the tank.
1020 × 
= 6.1 × 
= 598039.21 
We know that
= W × L × H
598039.21 = 300 × 80 × H
H = 25 m
Therefore the bottom of the sea is 25 m below sea level.
Most likely gravity, because the gravity would pull it off course or wobble.
