Q.5 Let $f: (0, \infty) \rightarrow \mathbb{R}$ be a function, and $\mathbf{r} = x\mathbf{i} + y\mathbf{j} + z\mathbf{k}$ denote the position vector in three dimensions. (6+6) (a) Show that $\nabla \cdot (f(|\mathbf{r}|) \mathbf{r}) = 3f(|\mathbf{r}|) + f'(|\mathbf{r}|)|\mathbf{r}|$. (b) Find the function $f$ such that $\nabla \cdot (f(|\mathbf{r}|) \mathbf{r}) = f(|\mathbf{r}|)$.

The hydrolysis of an organic compound is known to be mainly base-catalyzed with a rate constant of \( \mathrm{kb} \) : 0.98 1/M.s. Calculate the half-life of this compound assuming pseudo-first order kinetics for its degradation at a \( \mathrm{pH} \) of 10 and a starting concentration of \( 10^{-3} \mathrm{M} \). How will the half-life change if the reaction has zero-order kinetics? Compare the corresponding half-lifes assuming the same rate of hydrolysis in zero-order with the unit of \( \mathrm{M} / \mathrm{s} \). How will the result change if the starting concentration is \( 10^{-1} \mathrm{M} \) for both cases?

If a business makes the determination that an investment makes sense at the current interest rate, but before it can act, the interest rates fall Group of answer choices the business will have to recalculate whether it still makes sense. it will only make the situation better, so the business will clearly make the investment. it will cause the business to not make the investment regardless of the decrease. the business will go ahead with the investment because interest rates have nothing to do with whether an investment makes sense.

- In an argument, there must be at least one statement that intends to provide evidence or reasons. - The simple statements inside a conditional statement can be reexpressed to form an argument. - The antecedent of a conditional statement expresses a necessary condition for the consequent. - Indicator words such as "therefore" and "since" are not required to have an argument. - Deciding whether a factual claim is true usually falls outside the domain of logic. - Sometimes it is unclear whether an expository passage should be interpreted as an argument. - A report about an argument is not itself an argument. - The purpose of an expository passage is to prove that the topic sentence is true. - Expository passages and arguments are mutually exclusive. - The antecedent of an "if... then..." statement follows the word "then."
