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.

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]

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.

The piecewise function f(x) has opposite expressions. F(x) = startlayout enlarged left-brace 1st row 1st column 2 x minus 1, 2nd column x less-than 0 2nd row 1st column 0, 2nd column x = 0 3rd row 1st column negative 2 x + 1, 2nd column x greater-than 0 which is the graph of f(x)?.
The piecewise expression presented in the question gives values of f(x)
that change based on the range of the input value, x.
The graph of the piecewise expression f(x) is attachedReasons:
The given piecewise function is presented as follows;
[tex]f(x) = \begin{cases}2 \cdot x - 1, & \text{ if } x < 0 \\0, & \text{ if } x = 0\\-2 \cdot x + 1, & \text{ if } x > 0 \end{cases}[/tex]Required:
To find the graph of f(x)
Solution:
From the piecewise function, we have;
For x < 0, f(x) = 2·x - 1The slope, m = 2
Therefore, as x tends to 0, f(x) tends to 2×0 - 1 = -1
Therefore, for x < 0, the graph starts with an open circle at f(x) = -1, and f(x) decreases as graph moves from right to left.
At x = 0, f(x) = 0, which represent a point on the graphFor x > 0, f(x) = -2·x + 1
Which gives that as x tends to 0, f(x) tends to +1
The slope of the graph, m = -2
Therefore, the graph is a straight line that starts with an open circle at f(x) = +1 and slopes downwards from left to right.
