______ is the surgical repair of a testicle in the scrotum.

Write and simplify, but do not evaluate, an integral with respect to x that gives the length of each of the following curves on their respective interval. ( a )     y = 3 x ,     1 ≤ x ≤ 5 ( b )     y = 2 cos ⁡ x ,     0 ≤ x ≤ π {“version”:”1.1″,”math”:”(a)\ \ y=\frac{3}{x},\quad \ \ 1\leq x\leq 5\\ (b)\ \ y=2\cos x, \quad \ \ 0\leq x\leq \pi “}

In the text box, write the value of the definite integral. Submit pictures of your work / reasoning to Gradescope to be graded.

Set up the integral to compute the length of the parabola  y = 4 x 2 + 3 {“version”:”1.1″,”math”:”y=4 x^2+3″}between the points (-2,19) and (3,39). Simplify the integrand, but do not evaluate the integral.

Balance the following equation. Enter just the number (no spaces or any other characters.). If the coefficient is 1 (one) enter the number 1 otherwise Canvas will mark it unanswered and you will lose the points. [a] HClO4   + [b]  P4O10 (g)  →  [c] H3PO4(g)  +  [d] Cl2O7

Which of the following (with specific heat capacity provided) would show the largest temperature change upon gaining 200.0 J of heat?

Balance the following equation. Enter just the number (no spaces or any other characters.). If the coefficient is 1 (one) enter the number 1 otherwise Canvas will mark it unanswered and you will lose the points. [a] C7H9   + [b]  HNO3  →  [c] C7H6(NO2 ) 3  +  [d] H2O(g)

A coffee-cup calorimeter contains 100.0 mL of 1.000 M HCl (excess) at 20.3 °C. When 1.82 g Zn(s) is added, the temperature rises to 30.5 °C. What is the heat of reaction per mol Zn? Assume that the heat of solution is that of water, and the density of the HCl is 1.000 g/mL.  Zn(s)  + 2 HCl(aq)  → ZnCl2(aq)  + H2(g)   

Balance the following equation. Enter just the number (no spaces or any other characters.). If the coefficient is 1 (one) enter the number 1 otherwise Canvas will mark it unanswered and you will lose the points. [a] KNO3   + [b]  H2CO3  →  [c] K2CO3  +  [d] HNO3
