A semicircular plate with radius r = 2 is submerged in water as seen in the picture. Using the facts that the density of water is 1000 kg/m³ and acceleration due to gravity is 9.8 m/s², calculate the fluid force (in N) against the side of the plate. Make sure your answer is correct to three decimal places at least.

A passenger is standing on a scale in an elevator. The building has a height of 500 feet, the passenger has a mass of 80 kg, and the scale has a mass of 7 kg. The scale sits on the floor of the elevator. (It is an Otis elevator, so we will label it as "O" so as not to confuse its forces with those caused by the earth.) You may take g = 10 N/kg. For doing this problem it might be useful to start by drawing free-body diagrams for the passenger and the scale.Consider the vertical forces acting on the passenger and the scale WE→P: The force of the earth pulling down on the passenger (weight). WE→S: The force of the earth pulling down on the scale (weight). NP→S: The force of the passenger pushing down on the scale (normal). NS→P: The force of the scale pushing up on the passenger (normal). NO→S: The force of the elevator pushing up on the scale (normal). NO→P: The force of the elevator pushing up on the passenger (normal) a) While it is accelerating downward, which of the forces in your…

help Find the density of a fluid that has a mass of 3496 kg and occupies a volume of 15 m3.

The tank in the figure is 120 cm long into the paper. Determine the horizontal and vertical hydrostatic forces on the quarter-circle panel AB. The fluid is water at 20°C.
