Answer: 1960 kPa
Step-by-step explanation:
The pressure exerted on a body at a certain depth in a fluid can be calculated using the equation:
Pressure = Density x Gravity x Depth
Where Density is the density of the fluid, Gravity is the acceleration due to gravity and Depth is the distance below the surface of the fluid.
In this case, the density of the fresh water is 1000 kg/m³, the depth of the body is 200m and the acceleration due to gravity is 9.8 m/s².
So the pressure exerted on the body can be calculated as:
Pressure = 1000 kg/m³ x 9.8 m/s² x 200m
Pressure = 1960000 N/m²
Pressure = 1960 kPa
Therefore, the pressure exerted on the body with a mass of 75 kg at 200m below the surface of fresh water with a density of 1000 kg/m³ is 1960 kPa.
