Find a potential function for F or determine that F is not conservative. (If F is not conservative, enter NOT CONSERVATIVE.) F = cos(z), 10y, - x sin(z)

Answers

For $F$ to be conservative, we need to have

$(\partial f)/(\partial x)=\cos z$

$(\partial f)/(\partial y)=10y$

$(\partial f)/(\partial z)=-x\sin z$

Integrate the first PDE with respect to $x$ :

$\displaystyle\int(\partial f)/(\partial x)\,\mathrm dx+\int\cos z\,\mathrm dx\implies f(x,y,z)=x\cos z+g(y,z)$

Differentiate with respect to $y$ :

$(\partial f)/(\partial y)=10y=(\partial g)/(\partial y)\implies g(y,z)=5y^2+h(z)$

Now differentiate $f$ with respect to $z$ :

$(\partial f)/(\partial z)=-x\sin z=-x\sin z+(\mathrm dh)/(\mathrm dz)\implies(\mathrm dh)/(\mathrm dz)=0\implies h(z)=C$

So we have

$f(x,y,z)=x\cos z+5y^2+C$

so $F$ is indeed conservative.

When rolling two standard cubes (6-sided die), what is the probability that you roll sum of 11? Convert your answer to decimal form, then round to 3 decimal places

Answers

Answer:

Step-by-step explanation:

There are only two ways to roll a sum of 11 (5,6),(6,5) out of 36 possible outcomes so

P(11)=2/36=1/18

as a rounded decimal 0.056

A student heats 100 g of aluminum to 60°C. He places it in 100 g of water at 20°C. Over time, what will most likely happen?a. The water's temperature will increase slightly, and the metal's temperature will decrease a lot.

b. The water's temperature will increase a lot, and the metal's temperature will decrease slightly.

c. The water's temperature will decrease slightly, and the metal's temperature will increase a lot.

d. The water's temperature will increase by about the same amount as the metal's temperature decreases.

Answers

What is relevant here is that both water and metal have the same weight - if they had a different weight, one of them would change the temperature more than the other. (the one with more weight would change less).
But in the present case:

d. The water's temperature will increase by about the same amount as the metal's temperature decreases.

Answer:

Option A

Step-by-step explanation:

Given : A student heats 100 g of aluminum to 60°C. He places it in 100 g of water at 20°C.

To find : Over time, what will most likely happen?

Solution :

We know,

Heat will flow out of the warm aluminum and into the cool water.

The final "equilibrium" temperature will be a little less than 40°C (the average of 60° and 20°), because the specific heat of the aluminum is about 8% less than the specific heat of the water.

So when some quantity of heat flows from the aluminum to the water, the temperature of the water rises a little less than the temperature of the aluminum falls.

Therefore, Option A is correct.

The water's temperature will increase slightly, and the metal's temperature will decrease a lot.

Which point lies on the graph of y = |x - 1|

Answers

Answer: To determine which point lies on the graph of y = |x - 1|, we need to substitute different values of x into the equation and find the corresponding y-values.

Let's consider a few examples:

1. If x = 0:

y = |0 - 1| = |-1| = 1

So the point (0, 1) lies on the graph.

2. If x = 1:

y = |1 - 1| = |0| = 0

So the point (1, 0) lies on the graph.

3. If x = 2:

y = |2 - 1| = |1| = 1

So the point (2, 1) lies on the graph.

4. If x = -1:

y = |-1 - 1| = |-2| = 2

So the point (-1, 2) lies on the graph.

Based on these examples, we can see that points such as (0, 1), (1, 0), (2, 1), and (-1, 2) lie on the graph of y = |x - 1|. These are just a few examples, and there are infinitely many points that lie on the graph since the absolute value function is defined for all real numbers.
