Beginning around 5,500 years ago, the Sumerians built cities along the rivers in Lower Mesopotamia, specialized, cooperated, and made many advances in technology. The wheel, plow, and writing (a system which we call cuneiform) are examples of their achievements.
Answer:
C
Explanation:
V=1/p
By means of cross multiplication so by that we will have pv=1 which also implies p1v1=p2v2 coz boyles law states that the volume of a given mass of gas is inversely proportional to pressure provided that the temperature in kelvin remains constant
A charge-coupled device (CCD) is a light-sensitive integrated circuit that captures images by converting photons to electrons.
A touch screen is a computer display screen that is also an input device. The screens are sensitive to pressure; a user interacts with the computer by touching pictures or words on the screen.
The similarity is the sensitivity.
The difference is CCD scans or ‘takes images’, whereas touch-screen is where a user interacts with the software.

Answer:
ΔS = 7.618 J/K
Explanation:
The entropy change associated to an isothermal process is:
ΔS = 
We can calculate Q (heat) how:
Q = nRTln(
)
Where Vf = 2.5v
Vi = v
R = 8.314J/mol.k (Constant of ideal gases)
n: Number of moles = 1 mol
Then
Q = nRTln(2.5)
ΔS = 
ΔS = (1)(8.314)ln(2.5)
ΔS = 7.618 J/K
Answer:
W = y (b-a) / ab
Explanation:
Work is defined by the expression
W = ∫ F. dr
In this case the force is in the same direction of displacement, so the scalar product is reduced to the ordinary product
W = ∫ F dr
The expression of the strength left is
F = -y / x²
let's replace and integrate
W = ∫ (-y / x²) dx
W = -y (-1 / x)
We evaluate between the lower limit x = b + a to the upper limit x = 0 + a
W = -y (-1 / b + 1 / a)
W = y (b-a) / ab
where (b-a) is the distance traveled
