Based on the information provided by these technicians, both of them are correct.

According to heating, ventilation, and air conditioning (HVAC), heat in an air-conditioning system generally flows from the hotter object to the colder object.

As the refrigerant evaporates in a small radiator-type unit (evaporator), it absorbs heat as it changes phase from liquid to gas. Also, as the heat is being absorbed by the refrigerant, the small radiator-type unit (evaporator) becomes cold.

Explanation:

The Cost of 1 kilowatt hour of energy at the rate of $0.75 per 1.5 watt hour is $500 which is 5000 times greater than the cost of energy at $0.10 per kilowatt hour.

Battery power = Current × Voltage

Cost of 1.5 Watt-hour = $0.75

Converting Energy to Watt - hour :

1 kilowatt = 1000 watt

1 kilowatt hour = 1000 watt - hour

Hence,

Cost of 1 kilowatt - hour = 1000 watt - hour can be calculated thus :

1.5 Watt-hour = $0.75

1000 Watt-hour = c

Cross multiply :

1.5c = $0.75 × 1000

1.5c = 750

c = 750 / 1.5

c = 500

Therefore, cost of 1 kilowatt - hour of energy will be $500

Comparing the cost of Energy at $500 per Kilo-Watt hour to Cost at $0.10:

$500 / $0.10 = 5000

Therefore, the cost of energy at $500 per kilowatt hour is 5000 times greater than cost at $0.10 per kilowatt hour.

The correct answer is a) Here is a diagram of the milling circuit with labels: The product from the SAG mill is fed to the two ball mills in parallel, with the product from the ball mills being combined and classified in cyclones. The underflow from the cyclones is recycled, and the overflow goes to the flotation circuit.

To calculate the mass rate of each size fraction in each stream, we can start with the total feed rate of 1,500 t/hr. Since 25% of the feed is below 75 microns, that means 75% of the feed is above 75 microns. Of that 75%, 50% will be broken down in the SAG mill to below 75 microns, while the remaining 50% will be broken down in the two ball mills in parallel. Therefore: Mass rate of particles above 75 microns in feed = 1,500 x 0.75 = 1,125 t/hr Mass rate of particles below 75 microns in feed = 1,500 x 0.25 = 375 t/hr Mass rate of particles above 75 microns in SAG mill product = 1,125 x 0.5 = 562.5 t/hr Mass rate of particles below 75 microns in SAG mill product = 1,125 x 0.5 + 375 = 937.5 t/hr Mass rate of particles above 75 microns in each ball mill product = 562.5 / 2 = 281.25 t/hr Mass rate of particles below 75 microns in each ball mill product = 375 / 2 = 187.5 t/hr Mass rate of particles above 75 microns in combined ball mill product = 562.5 t/hr Mass rate of particles below 75 microns in combined ball mill product = 375 t/hr + 187.5 t/hr = 562.5 t/hr Mass rate of particles above 75 microns in cyclone overflow = 562.5 t/hr x 0.95 = 534.38 t/hr (assuming a 5% bypass) Mass rate of particles below 75 microns in cyclone overflow = 562.5 t/hr x 0.05 + 375 t/hr x 0.95 = 393.75 t/hr (assuming a 5% bypass) Mass rate of particles above 75 microns in cyclone underflow/recycle = 562.5 t/hr x 0.05 = 28.13 t/hr Mass rate of particles below 75 microns in cyclone underflow/recycle = 375 t/hr x 0.05 + 187.5 t/hr = 205.63 t/hr To calculate the feed rate to each ball mill, we can use the mass rate of particles below 75 microns in the combined ball mill product, which is 562.5 t/hr. Since there are two ball mills in parallel, the feed rate to each ball mill will be: Feed rate to each ball mill = 562.5 t/hr / 2 = 281.25 t/hr Finally, to calculate the percentage passing 75 microns in the circuit product.

Answer:

A) 211.81 m

B) 65°

Explanation:

We are told that the first friend hits a golf ball on level ground with an initial speed of 47 m/s at an angle of 35° above the horizontal.

Thus;

speed; u = 47 m/s

Projection angle; θ = 35°

A) We want to find how far away from the golfer the ball lands. This is simply the range. Range in projectile motion is given by the formula;

R = (u²•sin 2θ)/g

Plugging in the relevant values, we have;

R = (47² × sin(2 × 35))/9.8

R = 211.81 m

B) We are told that the second ball, travels the same horizontal distance as what is found in part (a).

Thus, R remains 211.81 m

Thus, the angle above horizontal of the initial velocity of this second golf ball will be;

90° - projection angle(θ) = 90 - 35 = 65°

Answer:

The equilibrium temperature is 109.7°C

The total entropy change for the process is 0.23 kJ/K

Explanation:

The parameters given are;

The initial temperature of aluminium, T₁ₐ = 140°C = 413.15 K

Mass, m₁, of aluminium block = 28 kg

The specific heat of aluminium, c₁, at 400 K = 0.949 kJ/(kg·K)

The initial temperature of iron, T₁ₙ = 60°C = 333.15 K

Mass, m₂, of iron block = 36 kg

The specific heat of iron, c₂, at room temperature = 0.45 kJ/(kg·K)

The heat lost by the aluminium = Heat gained by the iron

The heat lost by the aluminium = m₁ × c₁ × (T₁ₐ - Tₓ)

The heat lost by the aluminium = 28 × 0.949 × (413.15 - Tₓ)

The heat gained by the iron =  m₂ × c₂ × (Tₓ - T₁ₙ)

The heat gained by the iron =  36 × 0.45 × (Tₓ - 333.15)

Hence;

28 × 0.949 × (413.15 - Tₓ) = 36 × 0.45 × (Tₓ - 333.15)

26.572 × (413.15 - Tₓ) = 16.2 × (Tₓ - 333.15)

∴ (26.572 + 16.2) × Tₓ = 26.572 × 413.15 + 16.2 × 333.15

42.772·Tₓ = 16375.2518

Tₓ = 382.85 K = 109.7°C

The total entropy change of the process is given by the following relation;

\(\Delta S = \Delta S_{Fe} + \Delta S_{Al}\)

\(=m_{1}c_{1}ln\dfrac{T_{x}}{T_{1n}}+m_{2}c_{2}ln\dfrac{T_{x}}{T_{1a}}\)

\(=28 \times 0.949 \times ln\dfrac{382.85}{413.15}+36 \times 0.45 \times ln\dfrac{382.85}{333.15} = 0.23 \, \dfrac{kJ}{K}\)

While electric vehicles (EVs) offer many benefits over traditional gasoline-powered cars, there are some inconvenient truths about EVs that are worth considering:

Limited driving range: EVs have a limited driving range compared to gasoline-powered cars. Even the most advanced EVs on the market today typically have a range of around 300-400 miles on a single charge. This means that long-distance trips require careful planning and may involve multiple stops for charging.Charging infrastructure: The charging infrastructure for EVs is not yet as idespread or convenient as the gasoline refueling infrastructure. While many public charging stations are available, they may not be located in convenient locations, and charging times can be slow.Upfront cost: The upfront cost of an EV is generally higher than that of a comparable gasoline-powered car. Although the cost of batteries has been declining in recent years, it still represents a significant portion of the total cost of an EV.Battery degradation: Like all batteries, the batteries in EVs degrade over time, which can reduce their driving range and performance.

An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;

Reason:

The given parameters are;

Form of silo = Cylinder surmounted by a hemisphere

Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall

Required:

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum

Solution:

The fixed volume of the silo, V, can be expressed as follows;

\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)

Where;

h = The height of the cylinder

r = The radius of the cylinder

The surface area is, Surface Area = 2·π·r·h + 2·π·r²

The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²

Therefore;

\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)

At the minimum value, we have;

Which gives;

16·π·r³ = 6·V

Which gives;

\(h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r\)

h = 2·r

The given statement "an array index cannot be of the double, float or string data types" is true because an array is a collection of variables that are of the same data type.

Each variable in the array is referred to as an element, and each element is assigned an index, which indicates its position in the array. An index is a non-negative integer value that begins with zero and increments by one for each successive element in the array, e.g. array[0], array[1], array[2], etc.

The length of an array is determined by the number of elements it contains. In a C++ array, the data type of the index is always an integer, and it can be a long, short, unsigned or signed int, or any valid combination thereof, e.g. int x[10];

For example: double arr[5];int i;for(i=0; i<5; i++) { arr[i] = i + 0.5; } This code will cause an error since the index must be an integer. Double, float, or string data types cannot be used as indexes.
