what is a collection of computers that are all peers
A collection of computers that are all peers is known as a peer-to-peer network. In a peer-to-peer (P2P) network, each device or node in the network is treated as equal and can act as both a client and server in sharing files and resources among other devices on the network.
A peer-to-peer network is usually used in smaller networks, such as a small office or a group of computers in a home network. The biggest advantage of P2P networks is that they are easy to set up and do not require a dedicated server. These networks do not have a centralized server to manage the communication between nodes. Instead, each node in the network communicates with other nodes directly and in real-time.
Each node on the network can share resources, such as files, printers, and storage devices, with other nodes on the network. This makes it a cost-effective solution for small organizations or groups that need to share resources without investing in expensive network infrastructure.On the other hand, a disadvantage of P2P networks is that they can be less secure than client-server networks, as each node is connected directly to other nodes on the network. This makes it easier for malware and viruses to spread between devices on the network.
Additionally, without a centralized server to manage network traffic, P2P networks can become slow and congested as more nodes join the network.

Ore mined is processed at the Kalgold plant where the crushing circuit consists of a primary jaw
crusher, a screen and a secondary cone crusher. The primary crusher is located adjacent to the
pit and is in open circuit, with the crusher product being conveyed to the plant. In the plant this
material is fed into the cone crusher, which is in closed circuit with a screen which takes the
product from this crusher. The product from this circuit is the feed to the mill circuit:
The total solid feed to the primary crusher is 1200 t/hr. In analysing the performance of this
circuit, consider two size fractions, namely the particles larger than 1cm and those passing 1cm.
In the feed to the primary crusher only 15% of the material is already finer than 1cm. Assume
that the jaw crusher will break 30% of the material coarser than 1cm to finer than this size, while
the cone crusher will break 50% of the material above 1cm to finer than this size. Assume that
the screen’s performance is such that the partition number for the coarser particles is 0.8, while
it is 0.3 for the finer particles.
Carry out a mass balance over the circuit calculating the mass flowrates of each of the
components in each of the streams. What is the percentage passing 1cm in the crusher circuit
product/mill circuit feed?
We need to calculate the mass flowrates of each of the components in each of the streams and the percentage passing 1 cm in the crusher circuit product/mill circuit feed.
To calculate the mass flowrate of each component in each of the streams: F = C + T (1)
Where,
F = Feed flowrate (t/hr)
C = Circuit product flowrate (t/hr)
T = Tail flowrate (t/hr)
Circuit Flowrate:CF = QF × CF(2)
Where,
CF = Circuit flowrate (t/hr)
QF = Fractional volumetric flowrate of the stream
CF = VCF × γF (3)
Where,
VC = Volumetric flowrate of the stream (m3/hr)
γ = Density of the stream (t/m3)
Stream 1 - Feed to Primary Crusher: The total solid flowrate to the primary crusher is 1200 t/hr.
Let the fractional flow of particles larger than 1cm be F1 and that passing 1cm be F2.
F1 = 1 - 0.15 = 0.85
F2 = 0.15C1 = 0.3 × 0.85 × 1200 = 306 T/hr (material broken by jaw crusher larger than 1cm)
C2 = 0.5 × 0.15 × 1200 = 90 T/hr (material broken by cone crusher larger than 1cm)
T1 = (1 - 0.3) × 0.85 × 1200 = 714 T/hr
T2 = (1 - 0.5) × 0.15 × 1200 = 60 T/hr
Stream 2 - Product from Primary Crusher: The product from the primary crusher is the feed to the secondary cone crusher.
F1 = 0.7
F2 = 0.3
C1 = 0.8 × 0.7 × 306 = 171.36 T/hr (material not broken by secondary cone crusher and coming back to primary crusher)
C2 = 0.5 × 0.7 × 306 + 0.3 × 90 = 143.1 T/hr (material broken by secondary cone crusher larger than 1cm)
T1 = (1 - 0.8) × 0.7 × 306 = 48.96 T/hrT2 = (1 - 0.5) × 0.7 × 306 = 107.1 T/hr
Stream 3 - Product from Secondary Cone Crusher: The product from the secondary cone crusher is fed to the mill circuit.
F1 = 0.7,
F2 = 0.3
C1 = 0.8 × 0.3 × 143.1 + 0.7 × 171.36 = 235.32 T/hr
C2 = 0.5 × 0.3 × 143.1 = 21.47 T/hr
T1 = (1 - 0.8) × 0.3 × 143.1 = 28.62 T/hrT2 = (1 - 0.5) × 0.3 × 143.1 = 35.84 T/hr
Stream 4 - Mill Circuit Feed: The product from the secondary cone crusher is fed to the mill circuit.
F1 = 0.7,
F2 = 0.3.C1 = 235.32 T/hr
C2 = 21.47 T/hrT1 = 48.96 T/hr
T2 = 107.1 T/hr
Percentage passing 1 cm in the crusher circuit product/mill circuit feed:
Percentage passing 1 cm in the crusher circuit product = 100 × (T2 of Stream 2)/(C1 of Stream 2) = 100 × 107.1/235.32 = 45.51%
Percentage passing 1 cm in the mill circuit feed = 100 × (T2 of Stream 4)/(C1 of Stream 4) = 100 × 107.1/235.32 = 45.51%
Hence, the percentage passing 1cm in the crusher circuit product/mill circuit feed is 45.51%.

To calculate the Free Cash Flow (FCF) in Year 2, we need to consider various financial factors. Firstly, let's calculate the contribution margin, which is the sales price per unit minus the variable cost per unit. The contribution margin per unit is ($9.00 - $4.00) = $5.00.
Next, we calculate the total contribution margin by multiplying the contribution margin per unit by the increase in output: $5.00 x (5,000,000 - 1,000,000) = $20,000,000.
Then, we need to calculate the total fixed costs, which include the increased fixed costs and the allocated head office costs: $8,500,000 + $250,000 = $8,750,000.
Now, we can calculate the EBIT (Earnings Before Interest and Taxes) by subtracting the total fixed costs and the depreciation from the total contribution margin:
$20,000,000 - $8,750,000 - $350,000 = $10,900,000.
To calculate the interest expense, we multiply the loan amount by the interest rate:
$2,000,000 x 0.06 = $120,000.
Next, we calculate the taxable income by subtracting the depreciation of the old machine from the EBIT:
$10,900,000 - $105,000 = $10,795,000.
The tax expense is then calculated by multiplying the taxable income by the tax rate: $10,795,000 x 0.10 = $1,079,500.
Finally, we can calculate the Free Cash Flow (FCF) by subtracting the interest expense and the tax expense from the EBIT: $10,900,000 - $120,000 - $1,079,500 = $9,700,500.
Since this calculation represents the Free Cash Flow (FCF) in Year 2, we need to adjust for the depreciation of the new machine, which is $350,000.
Therefore, the FCF in Year 2 is $9,700,500 + $350,000 = $10,050,500.

what are the three separate capacities in the information processing model?
The information processing model consists of three separate capacities: sensory memory, short-term memory, and long-term memory.
1. Sensory memory is the initial stage of processing where sensory information from the environment is briefly held. It has a large capacity but a short duration, lasting only a few seconds. For example, when you see a word on a screen, it is briefly stored in sensory memory before moving on to the next stage.
2. Short-term memory, also known as working memory, is the second stage of processing. It has a limited capacity of about seven items and a duration of around 20 seconds. It is responsible for actively processing and manipulating information, like when you mentally rehearse a phone number before dialing it.
3. Long-term memory is the final stage of processing, where information is stored for longer periods. It has an unlimited capacity and can last a lifetime. Long-term memory is further divided into explicit (conscious) and implicit (unconscious) memories. For example, remembering a historical event is an explicit memory, while riding a bike is an implicit memory.
In summary, the information processing model consists of sensory memory, short-term memory, and long-term memory, each with different capacities and durations.
