In order for Ren who runs a harmburger stand and needed to clean up a season's worth of grease buildup, the cleaning product that he should look for that can handle a layer of grease would be those caustic chemicals. These caustic chemicals <span>can be applied to break down the grease. When these grease are broken down, hot water can be applied to rinse it. These chemicals should be allowed to dwell on the surface of grease for a period of time to soften the grease buildup. Hope this answer helps.</span>
Rotational handle is a symbol with which you can rotate a graphic to any angle and that displays above the top center sizing handle.
Anchor on the other hand is the symbol that indicates the paragraph to which and image is attached, alignment is the placement of paragraph text relative to the left and right margins.
Only the speed will change because it is in motion
I’m pretty sure one increases just straight up velocity and the other is kind of a deceleration
Answer:
the wavelength λ of the light when it is traveling in air = 560 nm
the smallest thickness t of the air film = 140 nm
Explanation:
From the question; the path difference is Δx = 2t (since the condition of the phase difference in the maxima and minima gets interchanged)
Now for constructive interference;
Δx= 
replacing ;
Δx = 2t ; we have:
2t = 
Given that thickness t = 700 nm
Then
2× 700 =
--- equation (1)
For thickness t = 980 nm that is next to constructive interference
2× 980 =
----- equation (2)
Equating the difference of equation (2) and equation (1); we have:'
λ = (2 × 980) - ( 2× 700 )
λ = 1960 - 1400
λ = 560 nm
Thus; the wavelength λ of the light when it is traveling in air = 560 nm
b)
For the smallest thickness 
∴ 



Thus, the smallest thickness t of the air film = 140 nm
