2. (10 points) Given the matrix $A$ below, solve parts (a), (b), and (c). $\begin{aligned} A = \begin{bmatrix} 1 & 3 & -5 \\ 1 & 4 & -8 \\ -3 & -7 & 9 \end{bmatrix} \end{aligned}$ (a) Determine if the equation $Ax = 0$ has a non-trivial solution. (b) Solve $Ax = 0$ in parametric vector form and describe the solution set geometrically. (c) Does $Ax = b$ have a solution for each $b$ in $\mathbb{R}^3$? Justify your answer.

If an electron travels 0.260 m from an electron gun to a TV screen in 36.9 ns, what voltage was used to accelerate it? (Note that the voltage you obtain here is lower than actually used in TVs to avoid the necessity of relativistic corrections.)
Determine the infinite limit: \( \lim_{x \to 2^{-}} \frac{x + 2}{x^2 - 4} \)

A distance AB is observed repeatedly using the same equipment and procedures, and the results, in meters, are listed in Problems 3.7 through 3.10. Calculate (a) the line's most probable length, (b) the standard deviation, and (c) the standard deviation of the mean for each set of results. 3.7* 65.401, 65.400, 65.402, 65.396, 65.406, 65.401, 65.396, 65.401, 65.405, and 65.404 3.8 Same as Problem 3.7, but discard the 65.406 observation.
3: Motivation Unlocked: Tuesday, February 2, 2021 6:00 AM AST - Sunday, February 7, 2021 11:59 PM AST. In chapter 10 (section 79) of the textbook, you learned that motivation can be categorized into two types: extrinsic and intrinsic. In your own words, explain each type of motivation and provide an example (using a scenario) for each one. Feel free to share personal experiences as your examples. IMPORTANT: Your examples must be created by you (or describing your own experience). You CANNOT use examples from the textbook or tricky topic videos. Please create or explain your own unique examples to receive full points.
A 50 kg steel file cabinet is in the back of a dump truck. The truck's bed, also made of steel, is slowly tilted.\\ $\vec{\sum F} = m\vec{a}$ \\ a) Starting with Newton's Laws, calculate the size of the static friction force on the cabinet when the bed is tilted by 25° ($\mu_s = 0.85$ and $\mu_k = 0.60$).\\b) At what angle will the file cabinet begin to slide?\\ c) What is the magnitude of the friction force when the file cabinet is just about to slide?\\ $f_s \le \mu_s n$ \\ $w = mg$
