1. a.) DRAW AN ARROW ON THE FIGURE (NEAR) R, DENOTING THE POSITIVE DIRECTION OF FLOW Q1 ACROSS R1 BASED ON HOW YOU HAVE DRAWN THE ARROW, WHICH OF THE FOLLOWING IS THE CORRECT RESISTOR LAW FOR R1: i. pg(h-D) + Pa - (Ps + Pa) = 21 R1 ii. Ps + Pa - (g3h + Pa) = 21 R1 iii. Pgh + Pa - (Ps + Pa) = 21 R1 iv. Pgh + Pa - (Ps + Pa) = (Gmi + 21) R1 V. Ps + Pa - (g3h + Pa) = (Gmi - 21) R1 b.) GIVE A DIFFERENTIAL EQUATION TO MODEL THE HEIGHT h OF THE FLUID SYSTEM BELOW. (ASSUME THAT h > D.) NOTE THAT THE SYSTEM CONTAINS TWO INPUTS: Ps & Gmi Emi Rz h D AJ Ps R1 Pa 2 3 + 12x + 16x = f(t),

1. Draw a free-body diagram for the following situation (see figure). Two identical 15.0-kg balls, each 25.0 cm in diameter, are suspended by two 35.0-cm-long wires. The surfaces of the balls are perfectly smooth. Since the situation is symmetric, you only need to draw a diagram for one of the balls. 2. Draw a free-body diagram of a 1130-kg car that is held in place by a light cable on a very smooth ramp, which is tilted up at an angle of 25.0°. The cable is at an angle of 31.0° above the surface of the ramp. (See figure.) Write the x- and y-component equations for the net force acting on the car, with the x-direction parallel to the ramp (pointing up the ramp) and the y-direction perpendicular to the ramp (pointing up away from the ramp). Label all quantities with symbols and use those symbols in the component equations.
