Answer: U can answer a few questions of other people’s questions then the question that was covered it unlocks after answering some questions and u will be able to see it or u could get the app too and it doesn’t block at all
Explanation:
Answer:
a) D = 4.88 * 10^(-14) m^2 / s
b) <em>t </em>= 1.1 hr
Solution:
a) Magnesium in Aluminum diffusion:
D = Do * exp(-Qd / RT)
= (1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15)
= 4.88 * 10^(-14) m^2 / s
D = 4.88 * 10^(-14) m^2 / s
b) The composition remains same at say the distance Xo:
(Cx - Co) / (Cs - Co) = Constant
Xo^2 / D_{550} * <em>t </em>= Xo^2 / D_{450} * 15
D_{550} * <em>t </em>= D_{450} * 15
(1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15) * <em>t</em>
(4.88 * 10^(-14) m^2 / s) * 15
by, solving for <em>t </em>we get:
<em>t </em>= 1.1 hr
So, the time required is 1.1 hr.
Answer:
1. Hydrostatic pressure.
2. Pressure.
3. Equilibrium forces.
Explanation:
1. <u>Hydrostatic pressure</u>: pressure exerted by a stationary liquid. It is simply the pressure in a liquid such as water at a specific depth.
Mathematically, hydrostatic pressure is given by the formula;
Where:
- H.P is the hydrostatic pressure of a liquid.
- rho represents the density of a liquid.
- g is the acceleration due to gravity.
- d is the depth (height) of a liquid.
2. <u>Pressure</u>: it is the force in a direction perpendicular to a given surface area. Thus, it's typically measured in Newton per meters (N/m²).
Mathematically, pressure is given by the formula;
3. <u>Equilibrium forces</u>: a pair of forces whose resultant is zero. It is also referred to as balanced forces because the resultant of all the pair of forces acting on a body or system is at equilibrium (balanced).
It now difficult for computer technology as manufacturing cannot keep up with overwhelming transistor demand.
<h3>What was Moore's Law ?</h3>
Moore's Law is the one that talks about the fact that the number of transistors on a microchip is one that often goes up about two years always, even if the cost of computers is reduced.
Based on the above, It now difficult for computer technology as manufacturing cannot keep up with overwhelming transistor demand.
