![This image contains a set of calculus problems involving line integrals and vector fields. Below are the transcriptions and descriptions of each problem:
1. **Evaluate**
\[
\int_C 36x \, ds
\]
where \( C \) is the path \( y = 3x^2 \) from \( x = -2 \) to \( x = 0 \).
2. **Evaluate**
\[
\int_C (x + y + z) \, ds
\]
where \( C \) is the line segment from \((1, 2, 3)\) to \((0, -1, 1)\).
3. **Find the center of mass of the wire** in the shape of the semicircle \( x^2 + y^2 = 16 \), with \( y \geq 0 \), and density function given by \(\delta(x, y) = y\).
4. **Evaluate**
\[
\int_C f(x, y, z) \, ds
\]
where \( f(x, y, z) = xy \) and \( C \) is the elliptical helix given by \( x = 2 \sin t \), \( y = 3 \cos t \), \( z = t \), for \( 0 \leq t \leq \pi \).
5. **Consider the vector field**
\[
\mathbf{F}(x, y, z) = x^2y \, \mathbf{i} + (x^3 + 1) \, \mathbf{j} + 9z^2 \, \mathbf{k}.
\]
Let \( C \) be the circle of radius 2, oriented clockwise as …
This set of problems is focused on path integrals, center of mass calculations, and vector field analysis in multivariable calculus. Each problem requires evaluating integrals along specified paths and curves, involving techniques such as parameterization and the use of density functions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3544afac-2ad9-460f-8bb0-99e3f98e4a66%2Fe5b28211-771f-44bd-9694-9c59d485f2c1%2F3sbwgcy.jpeg&w=3840&q=75)
