Answer:
The flow of the electrons gets slower the more resistance added
The absolute pressure in psia being measured is; 27.228 psia
<h3>What is the absolute Pressure?</h3>
Formula for absolute Pressure is;
Absolute pressure = Atmospheric pressure + Gauge pressure
P_{abs} = P_{atm} + P_g
We are given;
P_atm = 29.86 (in Hg) = 14.666 psia
Density of mercury at 70 °F; ρ = 13.543 g/cm³
Mercury Manometer reading; h = 25.62 in
Acceleration due to gravity; g = 32.243 ft/s²
Gauge pressure of the mercury = ρgh = 13.543 * 25.62 * 32.243
When we multiply and covert to psia gives; P_g = 12.562 psia
Thus;
P_abs = 14.666 + 12.562
P_abs = 27.228 psia

Answer:
Explanation:
The rank of the magnitude of the diffusion coefficient from greatest to least is as follows:
C in Fe at 900°C > Cr in Fe at 900°C > Cr in Fe at 600°C
Reason
C in Fe is an interstitial impurity while Cr in Fe is a substutional impurity.Therefore interstitial impurity occurs in C in Fe systems,while substutitional diffusion occurs in Cr in Fe system.Interstitial is much faster than substitutional diffusion hence the order
Also with increasing temperature magnitude of diffusion coefficient increases,due to the relation.
D = D₀exp(-Qd/RT)
Where D₀=Temperature independent per exponential
Qd= The activation energy for diffusion
R= Universal gas constant
T=absolute temperature
Answer:
extrusive,
Explanation:
lava exlodes outwards, making it extrusive and not intrusive.
Answer:
16.38L
Explanation:
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties.
Quality is defined as the ratio between the amount of steam and liquid when a fluid is in a state of saturation, this means that since the quality is 50%, 1kg is liquid and 1kg is steam.
then to solve this problem we find the specific volume for ammonia in a saturated liquid state at 20C, and multiply it by mass (1kg)
v(amonia at 20C)=0.001638m^3/kg
m=(0.01638)(1)=0.01638m^3=16.38L
