We want to find
such that
. This means



Integrating both sides of the latter equation with respect to
tells us

and differentiating with respect to
gives

Integrating both sides with respect to
gives

Then

and differentiating both sides with respect to
gives

So the scalar potential function is

By the fundamental theorem of calculus, the work done by
along any path depends only on the endpoints of that path. In particular, the work done over the line segment (call it
) in part (a) is

and
does the same amount of work over both of the other paths.
In part (b), I don't know what is meant by "df/dt for F"...
In part (c), you're asked to find the work over the 2 parts (call them
and
) of the given path. Using the fundamental theorem makes this trivial:


2x1,000,000
9x100,000
3x10,000
7x1,000
0x100
8x10
2x1

Answer:
C. 1 lb. 9 oz.
Step-by-step explanation:
Answer: 1 1/3
All you do is see how many times 3 goes into 4 which is 1 so 1/3 and you add 1 so if added it equals 4 1 1/3
Can I get brainly its okay if no.
