Honestly idk you’ll need a better way to explain this
Answer:
2 inches
Step-by-step explanation:
it is ,2inches because they are joining
A three-dimensional vector field is conservative if it is also irrotational, i.e. its curl is
. We have
so this vector field is not conservative.
- - -
Another way of determining the same result: We want to find a scalar function
such that its gradient is equal to the given vector field,
:
For this to happen, we need to satisfy
From the first equation, integrating with respect to
yields
Note that
*must* be a function of
only.
Now differentiate with respect to
and we have
but this contradicts the assumption that
is independent of
. So, the scalar potential function does not exist, and therefore the vector field is not conservative.
The first term is 7, and the common difference is 4. We know this because 11-7=15-11=4. So the nth term is going to be 7+4(n-1). The 26th term will be 7+4(26-1)=7+100=107. The sum of the series is going to be (107+7)*13=1482.
