It is literally always hungry and massively obese, because the normal satiety signaling hormone â leptin â is absent from circulation. Researchers typically use the ob/ob mouse as a model for type II diabetes. When you inject an (obese) ob/ob mouse with leptin, it loses weight and its health markers normalize.
The tank pressure sensor is usually located on the top of the fuel pump assembly.
The pressure of the water on the bottom of the tank is (1 ton/m)(2 m) = 2 ton/m. bottom of the tank is F = (pressure) x (area of bottom) = (2 ton/m)(4 m)(3 m) = 24 tons. Since the bottom of the tank is horizontal, the pressure is the same everywhere on it, so there's no need to do integration.
