Determine whether or not the vector field is conservative. If it is conservative, find a function f such that f = ∇f. (if the vector field is not conservative, enter dne. ) f(x, y, z) = i + sin(z)j + y cos(z)k.
If F(x, y, z) = i + sin(z) j + y cos(z) k is conservative, then there exists a scalar function f(x, y, z) such that grad(f) = F, which means
∂f/∂x = 1
∂f/∂y = sin(z)
∂f/∂z = y cos(z)
Integrating each each of these equations gives
∫ ∂f/∂x dx = ∫ dx ⇒ f(x, y, z) = x + α(y, z)
∫ ∂f/∂y dy = ∫ sin(z) dy ⇒ f(x, y, z) = y sin(z) + β(x, z)
∫ ∂f/∂z dx = ∫ y cos(z) dz ⇒ f(x, y, z) = y sin(z) + γ(x, y)
It follows that α(y, z) = y sin(z) and β(x, z) + γ(x, y) = x + C where C is a constant. So
f(x, y, z) = x + y sin(z) + C
and F is indeed conservative.

An astronaut in the space station appears weightless because the astronaut seems to float. Which of the following claims is true about the force exerted on the astronaut by earth?.
Answer:
The force exerted on the astronaut by Earth is equal to the force exerted on Earth by the astronaut.
Explanation:
The claim that is true about the force exerted on the astronaut by the earth is equal to the force exerted on Earth by the astronaut. The correct option is D.
Who is an astronaut?An astronaut is a scientist who studies the bodies outside the earth. The galaxies, planets, and other astronomical units.
Newton's third rule of motion states that there is always an equal and opposite response to every action in nature. For example, if a first item exerts a specific amount of force on a second object, the second object will do the same but in the opposite direction.
As a result, the gravitational pull that Earth has on the astronaut is equivalent to the pull that the astronaut has on Earth.
Therefore, the correct option is D) the force exerted on the astronaut by Earth is equal to the force exerted on Earth by the astronaut.

C) the force exerted on the astronaut by Earth is equal to the gravitational force of the space station that is exerted on the astronaut; the two equal forces balance to cause the astronaut to float.
D) the force exerted on the astronaut by Earth is equal to the force exerted on Earth by the astronaut

Two numbers differ by 8 if their product is 713 then the sum of the two numbers is.
The sum of the two numbers is equal to 70.
Let the first number be x.Let the second number be y.In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
[tex]x-y=8[/tex] ....equation 1.
The product of the two numbers is 713:
[tex]xy=713[/tex] ....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
[tex]x=8+y[/tex] ....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
[tex]y(y+8)=713\\\\y^2+8y=713\\\\y^2+8y-713=0[/tex]
Solving the quadratic equation by factorization, we have:
[tex]y^2-31y +23y-713=0\\\\y(y-31)+23(y-31)=0\\\\(y+23)(y-31)=0[/tex]
y = -23 or 31.
For the value of x, when y = 31:
[tex]x=8+31[/tex]
x = 39
Now, we can calculate the sum of the two numbers:
[tex]x+y=39+31=70[/tex]

Pauline chasse has just signed a lease agreement with landlord, wayne godbrey to rent a house he owns in delano. The lease states definite beginning (january 1, 2016) and ending (october 30, 2016) dates, and sets forth the rent amount and due dates and all additional property and personal information required in such a lease. Wayne hands a copy to pauline, but she notices that he has not signed it. When she comments about this to him, he tells her that signatures are not necessary since the lease is for less than a year. Which of the following is true of this situation?.
The correct option that is true as regards Wayne's situation about the lease is;
B; Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).
The missing options are;
Under the Statute of Frauds in California,
A) leases of less than one year are not even required to be in writing, and therefore, signatures are not required.
B) Leases of less than one year are not required to be in writing. However, if a lease IS in writing, then it must be signed by the lessor (in this case, Wayne).
C) Leases of less than one year are not required to be in writing; but if there is a written lease, then it must be signed by both the lessee and lessor.
D) Because the property being leased is located in Northern California, a lease agreement is required to be both written and signed by the lessor if the lease period is for 6 months or more
Now, California has some principles that guide the regulation of the real estate industry and according to the California Principles of Real State, it has to be said that leases of less than one year are not required to be in writing. Now, even though the law stated that the consent of both parties are not enough to bind themselves in the lease agreement, it is recommended that just for the sake of keeping things legally binding as regards the agreement between both parties, then both parties may state it in written and the lessor must sign it.Read more about real estate statutes at; https://brainly.com/question/19655487

What chemical is added to natural gas in case of gas leaks? because natural gas is odorless and colorless, is added to provide a strong odor in case of gas leaks.
The chemical added to natural gas in case of gas leaks is mercaptan added to provide a strong odor in case of gas leaks as natural gas is odorless and colorless.
What are the uses of Natural Gas?Natural gas is used in the business sector as well as in households to cook, heat water, run refrigeration and air-conditioning systems, cook, dry clothing, and light up the night.
Methane is the principal carbon substance in natural gas. Natural gas is tasteless, colorless, and odorless, so gas companies add mercaptan to give it an unpleasant stench that can be used to detect leaks in natural gas pipes.
Natural gas is given the chemical mercaptan in order to make leaks simpler to find. The most crucial fact about mercaptan is that it smells bad. It has been compared by some to the stench of rotting eggs. Its odor is quite intolerable in concentrated form.
