Evaluate the surface integral
S |
F · dS
for the given vector field F and the oriented surface S. In other words, find the flux of F across S. For closed surfaces, use the positive (outward) orientation.
F(x, y, z) = x i + y j + z4 k
S is the part of the cone z =
x2 + y2 |
beneath the plane
z = 1
with downward orientation

You are standing at a base of a Ferris Wheel which is 4 m above ground while your friend is riding. The Ferris Wheel is 8m in diameter. Describe how the shape of the sine curve models the distance your friend is to the platform you are on. Identify the function that will model this situation as well as a function that will model the if we measure his distance to the ground. In your explanation use the following terms:

Assume the reader understands derivatives, and knows the
definition of instantaneous velocity (dx/dt), and knows how to
calculate integrals but is struggling to understand them. Use
students’ prior knowledge to provide an explanation that includes
the concept and physical meaning of the integral of velocity with
respect to time.
Reminder: The user is comfortable with the calculations, but is
struggling with the concept. To fully address the prompt, emphasize
the written explanation in English over the calculation.
