Create a variable myage and store your age in it. Subtract 2 from the value of the variable. Add 1 to the value of the variable. Observe the Workspace Window and Command History Window as you do this.

How can you make written and spoken messages most effective?

Estimate the flow rate and volume of water required to provide adequate fire protection to a five-story office building constructed of joisted masonry. The effective floor area of the building is 5000 m$^2$.

In a two slit interference pattern, the intensity at the peak of the central maximum is $I_{0}$. (a) At a point in the pattern where the phase difference between the waves from the two slits is $60.0^{\circ}$, what is the intensity? (b) What is the path difference for 480-nm light from the two slits at a point where the phase difference is $60.0^{\circ}$?

A water molecule consists of two hydrogen atoms bonded with one oxygen atom. The bond angle between the two hydrogen atoms is $104^{\circ}$). Calculate the net dipole moment of a water molecule that is placed in a uniform, horizontal electric field of magnitude $2.3 \times 10^{-8} \mathrm{~N} / \mathrm{C}$. (You are missing some information for solving this problem; you will need to determine what information you need, and look it up.)

A Carnot engine operates between a hot reservoir at 320 K and a cold one at 260 K. If the engine absorbs 500 J as heat per cycle at the hot reservoir, how much work per cycle does it deliver?

Find the moment of inertia about the x-axis of a thin plate bounded by the parabola

$$x = y - y ^ { 2 }$$

and the line x + y = 0 if

$$\delta ( x , y ) = x + y.$$

Write a program to calculate the position of a projectile at a given time t. For an initial velocity v$_0$ and angle of departure $\theta_0$, the position is given by x and y coordinates as follows (note: the gravity constant g is 9.81 m/s$^2$ ):

$$\begin{aligned} & x=v_0 \cos \left(\theta_0\right) t \\ & y=v_0 \sin \left(\theta_0\right) t-\frac{1}{2} g t^2 \end{aligned}$$

The program should initialize the variables for the initial velocity, time, and angle of departure. It should then call a function to find the x and y coordinates, and then another function to print the results. If you have version R2016a or later, make the script into a live script.

Write a set of functions and design requirements for a gripper for a robot to grasp a spare tire assembly and insert it into the trunk of an automobile on an assembly line.

Which of the following are true statements about virtual images?

1. You can see a virtual image.
2. A virtual image must be larger than the object.
3. A virtual image is formed at the position from which the rays appear to have originated.
4. A virtual image must be upside down.

Steam enters a one-inlet, two-exit control volume at location (1) at $360^\circ C,$ 100 bar, with a mass flow rate of 2 kg/s. The inlet pipe is round with a diameter of 5.2 cm. Fifteen percent of the flow leaves through location (2) and the remainder leaves at (3). For steady-state operation, determine the inlet velocity, in m/s, and the mass flow rate at each exit, in kg/s.

A company manufactures a part for which there is a desired weight. There is a tolerance of N%, meaning that the range between minus and plus N% of the desired weight is acceptable. Create a variable that stores a weight and another variable for N [e.g., set it to 2]. Create variables that store the minimum and maximum values in the acceptable range of weights for this part.

Light traveling in air is incident on the surface of a block of plastic at an angle of $62.7^{\circ}$ to the normal and is bent so that it makes a $48.1^{\circ}$ angle with the normal in the plastic. Find the speed of light in the plastic.
