Refer to the diagram below to answer this question. A ripple tank is set up with two straight-wave generators at right angles to each other. Ripple tank Water Generator A Generator B Two wave trains are created using two straight-wave generators set up at right angles to each other in a ripple tank. Generator A creates a wave that has twice the frequency and twice the amplitude as the wave created by generator B. When the two wave trains created by generators A and B interact, they a. merge to form a single wave that travels in a direction halfway between the two original wave directions (as represented by the vector $$v_1$$). b. merge to form a single wave that travels in a direction between the two original wave directions, but mostly in the direction of the wave with the greatest amplitude (as represented by vector $$v_2$$). c. continue on in their original directions as they pass through each other. d. mutually destroy each other.

HW Problem 7 The following forces act on the patella (knee-cap) during the squat maneuver. Assuming that the forces act concurrently (at the same exact point), find the resultant of these forces. The following data is given: $\vec{F_1}, \theta_1 = [80 lb, 55°]$ $\vec{F_2}, \theta_2 = [90 lb, \downarrow]$ $\vec{F_3}, \theta_3 = [35 lb, 30°]$

What is the future worth of a series of equal year-end deposits of $3,000 for 15 years in a savings account that earns 9% annual interest if the following were true? (a) All deposits are made at the end of each year? (b) All deposits are made at the beginning of each year? Deposit Amount Number of Years Annual Interest Rate $3,000 15 9% Complete the steps below using cell references to given data or previous calculations. In some cases, a simple cell reference is all you need. To copy/paste a formula across a row or down a column, an absolute cell reference or a mixed cell reference may be preferred. If a specific Excel function is to be used, the directions will specify the use of that function. Do not type in numerical data into a cell or function. Instead, make a reference to the cell in which the data is found. Make your computations only in the blue cells highlighted below. In all cases, unless otherwise directed, use the earliest appearance of the data in your formulas, usually the Given Data section. (a) Future Worth (F) (b) Future Worth (F)

Problem 3: A large tank containing mostly water is held under pressure, with the pressure measured via a manometer with several fluids. Find the gauge pressure of the air inside the tank given the densities of the fluids: $\rho_{H_2O} = 1000 \text{ kg/m}^3$, $\rho_{oil} = 0.850\rho_{H_2O}$, and $\rho_{Hg} = 13.6\rho_{H_2O}$. Take the heights to be $h_1 = 0.7 \text{ m}$, $h_2 = 0.6 \text{ m}$, and $h_3 = 0.8 \text{ m}$.
