Hоw mаny оxygen аtоms аre in `x` molecules of dinitrogen tetroxide, N2O4?
A hydrоfоil is mаde up оf а front wing, bаck wing, mast, and a board. The mast is the vertical structure that connects the front and back wing to the board. When the wings move through water they provide forces which allow the board and the rider to lift out of the water. The rider has a weight of 155lb and the weight acts 24 inches in front of the mast The front wing provides a vertical force labeled F which acts 8 inches in front of the mast The back wing provides a vertical force labeled B which acts 20 inches behind the mast The mast has a length of 28 inches All of this is shown in the free body diagram provided. (The free body diagram is a simplification of the forces on a real hydrofoil just fyi) The forces on the wings are drawn in the positive y direction in the free body diagram. This does not nessesarly mean the actual force is in the positive y direction (it could be -y direction) Note the coordinate system defined in the diagram The hydrofoil is moving at constant velocity free body diagram of entire hydrofoil system Is the hydrofoil static? Explain why or why not in your written work
