Answer:
Negative.
Step-by-step explanation:
Negative integers represent decreasing or downward movement or to the left in the number line or direction.
Dives below the sea level denotes the downward movement. So, it is denoted by negative integer.
Objects moving downwards are assigned a (b) negative sign. 'Dives below the surface of the ocean' represents a negative number.
The phrase 'dives below the surface of the ocean' represents a negative number. When an object moves downward, it is conventionally assigned a negative sign (-). Therefore, diving below the surface of the ocean indicates a negative direction.
Regarding work being done in the context of physics, when an object is lowered, like lowering a bale of hay from a truck, the work done against gravity is considered negative because the force applied is in the opposite direction of the motion.
In the case of hydrostatic equilibrium, the pressure in the ocean increases as a diver goes deeper. So if you dive to a depth of 200 feet, you would expect the pressure to increase due to the weight of the water above exerting more force on you.
