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 elevator in a hotel starts at ground level. It rapidly moves up to the third floor, where it stops to unload passengers. The elevator then descends to the basement at a slower speed than before.
The graph correctly represents the story illustrated in the graph.
From the given graph, from the ground floor to the third floor is a rapid acceleration.
During the unload at the third floor, the velocity was constant until all the passengers was unloaded.
The deceleration of the elevator was slower than the acceleration because it occurred at a longer time.
Thus, we can conclude that the graph correctly represents the story illustrated in the graph.
The complete question is below:

Two samples of solids have similar reactivity with acids and similar densities. Their masses and volumes, however, are not at all similar. Is it possible that these are the same substance?.
The two samples may be the same substance even though they have different masses and volumes.
We must know that properties that identify a substance are called intensive properties. Samples that have similar intensive properties are likely to be the same substance since these properties are characteristic of the substance.
Density is an intensive property. If the two substances have similar densities and similar reactivity with acids, they may be the same substance even though they have different masses and volumes.

Which statement describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table?.
The statement that describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table is; The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.
The electronic configuration of arsenic is given as; 1s² 2s² 2p^(6) 3s² 3p^(6) 4s² 3d^(10) 4p³.
Now we can see that in that electronic configuration the orbitals are, s, p and D.
Now, the maximum electrons for each of the 3 orbitals are;
Maximum electrons for d orbital = 10 electrons
Maximum electrons for s orbital = 2 electrons
Maximum electrons for p orbital = 6 electrons.
Now, when we compare the maximum number of electrons for each orbital to the ones in electron configuration of arsenic, it is clear from the last 3 orbitals that the 3d and 4s orbitals are completely filled while the 4p orbital is half filled or partially filled.
