Answer: O D. A digital signal moves between a discrete number of values.

Explanation:

The digital signals are considered more reliable over the analog signals as they encode the information in a coded form. The bits or samples of the data are transmitted and converted into digital and numerical value. The stream of encoded data is in the form of continuous data at regular time intervals. It provides information in waveform and the data is in compact form. The data is in the form of binary bits 0 and 1 so greater the number of bits greater will be the greater will be the resolution of the information.

Create the Lewis structure of CF4. NOTE: do only the step asked for in each part and then click Check–don't work ahead to solve

Naya [18.7K]

To create the Lewis structure we need to take into account the octet rule: atoms tend to gain, lose or share electrons to complete their valence shell with 8 electrons.

C belongs to Group 4A in the periodic table so it has 4 valence electrons. It needs to share 4 pairs of electrons to complete the octet.

F belongs to Group 7A in the periodic table so it has 7 valence electrons. Each F needs to share 1 pair of electrons to complete the octet.

As a consequence, in CF₄, C will form a single bond with each F and all the octets will be complete.

Determine the new pressure of a sample of hydrogen gas if the volume and moles are constant, the initial pressure is

masha68 [24]

Answer:

6.3 atm

Explanation:

P2=T2P1/T1

Change C to K

We can check this by knowing that P and T at constant V have a proportional relationship; Hence, this is correct.

Calculate the pressure (psig) at the bottom of a 7500 foot column of fluid for each of the following fluids:

creativ13 [48]

Answer:

Pressure at the botton of 7500 ft column is:

a) P (water) = 3256.508 psig

b) P (drilling mud) = 4229.035 psig

c) P (gas lift) = 18.092 psig

d) P (Natural gas) = 17.092 psig

Explanation:

hidrostatic pressure:

P = ( d.f * g * h ) + Po

∴ density of fluid ( d.f ) ≡ Kg/m³

∴ aceleration o gravity ( g ) = 9.807 m/s²

∴ column height ( h ) = 7500 ft * ( m / 3.28084 ft ) = 2285.99 m

∴ atmospheric pressure (Po) = 101300 Pa ( Kg /m*s²)

specific gravity:

SG = d.f / d H2O (ref)

∴ d H2O = 997 Kg/m³

a) water:

⇒ P = ( 997 * 9.807 * 2285.99 ) + 101300

⇒ P = 22452844,88 Pa * ( psig / 6894.76 Pa ) = 3256.508 psig

b) Drilling Mud

⇒ SG = 1.3 = d.f / 997

⇒ d.f = 1296.1 Kg/m³

⇒ P = ( 1296.1 * 9.807 * 2285.99 ) + 101300

⇒ P = 29158182.16 Pa = 4229.035 psig

c) Gas lift column

⇒ SG = 0.85 = d.f / d.air (ref)

∴ d.air = 0.0765 Lb/ft³ = 1.23 Kg/m³

⇒ d.f = 1.23 * 0.85 = 1.0455 Kg/m³

⇒ P = ( 1.0455 * 9.807 * 2285.99 ) + 101300

⇒ P = 124738.755 Pa = 18.092 psig

d) Natural Gas column:

⇒ SG = 0.6 = d.f / 1.23

⇒ d.f = 0.738 Kg/m³

⇒ P = ( 0.738 * 9.807 * 2285.99 ) + 101300

⇒ P = 117845.003 Pa = 17.092 psig
