To find the number of electrons transferred to the screen in 60 seconds, we need to use the formula: Charge (Q) = Current (I) x Time (t).
We know the current (I) is 5x10^-6 ampere and the time (t) is 60 seconds. So, Q = 5x10^-6 x 60 = 3x10^-4 coulombs Now, we need to convert coulombs to electrons. We know that one coulomb is equal to 6.24x10^18 electrons. Therefore, the number of electrons transferred to the screen in 60 seconds is: 3x10^-4 coulombs x 6.24x10^18 electrons/coulomb = 1.872x10^15 electrons So approximately 1.872x10^15 electrons are transferred to the screen in 60 seconds.

To answer this question, we need to use the formula:
Charge (Q) = Current (I) x Time (t)
We know the current (I) is 5x10^-6 ampere and the time (t) is 60 seconds. We can plug these values into the formula to find the charge (Q):
Q = 5x10^-6 A x 60 s = 3x10^-4 coulombs
Now we need to use the fact that one electron has a charge of 1.602x10^-19 coulombs to find the number of electrons transferred:
Number of electrons = Charge / Charge of one electron
Number of electrons = (3x10^-4 C) / (1.602x10^-19 C/electron)
Number of electrons = 1.87x10^15 electrons
Therefore, approximately 1.87x10^15 electrons are transferred to the screen in 60 seconds.

2.) A fluid moves in a steady manner between two sections in a flow
line. At section 1: A2 = 10 ft?, V = 100 fpm, vl = 4 ftp/lb
At section 2: A2 = 2 ft², P2 = 0.20 lb/ft?
Calculate (a.) the mass flow rate, and
(b.) the speed at section 2
Answer:
\(250\ \text{lbm/min}\)
\(625\ \text{ft/min}\)
Explanation:
\(A_1\) = Area of section 1 = \(10\ \text{ft}^2\)
\(V_1\) = Velocity of water at section 1 = 100 ft/min
\(v_1\) = Specific volume at section 1 = \(4\ \text{ft}^3/\text{lbm}\)
\(\rho\) = Density of fluid = \(0.2\ \text{lb/ft}^3\)
\(A_2\) = Area of section 2 = \(2\ \text{ft}^2\)
Mass flow rate is given by
\(m=\rho A_1V_1=\dfrac{A_1V_1}{v_1}\\\Rightarrow m=\dfrac{10\times 100}{4}\\\Rightarrow m=250\ \text{lbm/min}\)
The mass flow rate through the pipe is \(250\ \text{lbm/min}\)
As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1
\(m=\rho A_2V_2\\\Rightarrow V_2=\dfrac{m}{\rho A_2}\\\Rightarrow V_2=\dfrac{250}{0.2\times 2}\\\Rightarrow V_2=625\ \text{ft/min}\)
The speed at section 2 is \(625\ \text{ft/min}\).
(a) The mass flow rate will be "250 lbm/min".
(b) At section 2, the speed will be "625 ft/min".
Speed and MassAccording to the question,
Section 1 area, A₁ = 10 ft²
Section 2 area, A₂ = 2 ft²
Water's velocity, V₁ = 100 ft/min
Volume at section 1, v₁ = 4 ft³/lbm
(a) We know the formula,
Mass flow rate, m = ρA₁V₁
= \(\frac{A_1 V_1}{v_1}\)
By substituting the values,
= \(\frac{10\times 100}{4}\)
= \(\frac{1000}{4}\)
= 250 lbm/min
(2) The speed will be:
→ m = ρA₂V₂
or,
V₂ = \(\frac{m}{\rho A_2}\)
By substituting the values,
= \(\frac{250}{0.2\times 2}\)
= \(\frac{200}{0.4}\)
= 625 ft/min
Thus the responses above are correct.

(d) Why might a blue orange be more difficult to represent by the developed brain than an orange-coloured orange. Explain your answer. How might this example inform the localist versus distributed debate? [3 marks] (e) Assuming a two-by-two input array, depict a set of four similar and four dissimilar input patterns. [2 marks]
A blue orange may be more difficult to represent by the developed brain compared to an orange-colored orange due to the mismatch between the expected color association and the perceived color.
This example highlights the challenges of representing an object with an unconventional or unexpected color, which can inform the localist versus distributed debate in terms of how the brain processes and represents sensory information.
The human brain has developed associations between certain objects and their typical colors based on prior experiences and learned associations. For example, oranges are commonly associated with the color orange. When encountering an orange-colored orange, the brain can easily match the perceived color with the expected color association.
However, when presented with a blue orange, there is a mismatch between the expected color association (orange) and the perceived color (blue). This discrepancy can lead to cognitive processing difficulties as the brain tries to reconcile the unexpected color with the known object. The representation of the blue-orange may be more challenging because it requires overriding the preexisting color association and establishing a new color-object association.
This example informs the localist versus distributed debate, which pertains to how sensory information is processed and represented in the brain. The localist perspective suggests that specific representations are localized to distinct brain regions, while the distributed perspective proposes that representations are distributed across multiple brain regions. The difficulty in representing a blue orange demonstrates the complexities involved in integrating and reconciling conflicting sensory information, supporting the argument for a distributed processing approach where multiple brain regions work together to form representations.

Consider a vertical piston/cylinder system. The piston has a mass of 35 kg and has an unknown radius. There is a pressure gauge to output the pressure inside the cylinder. If the piston is compressed and the pressure gauge reads 300 kPa. What is the area of the piston
Answer:
Area of the piston = 1.143 * 10^-3 m^2
Explanation:
Here, we are tasked with calculating the area of the piston.
Mathematically, the area of the piston =
Piston force/ cylinder pressure
From the question,
Piston force = mg where m is the mass of the piston = 35 kg and g is the acceleration due to gravity = 9.8 m/s^2
Thus, piston force = 35 * 9.8 = 343 N
Now the pressure gauge reads 300 KPa and 1KPa = 300 * 10^3 Pa = 300000 Pa
Thus, the area of the piston = 343/300000 =
0.001143333333 m^2 which is simply 1.143 * 10^-3 m^2

\(W=10.03(114.94-70 )+0.0184((114.94)^2-70^2 )\)
\(W=527.21btu/ibmole\)
\(W=11.982btu/ibm\)
Generally the equation for Efficiency is mathematically given by
\(E=\frac{isotropic Power}{Actual P'}\)
\(E=\frac{P}{P'}\)
Since
Isotropic Power
\(P=0.0167*11.982btu/ibm\)
\(P=0.2btu/s\)
Therefore
\(P'=\frac{0.2}{0.75}\)
\(P'=0266btu/s\)
