Answer:

The greatest mass, that the weight C can have such that block A does not move is approximately 23.259 kg

Explanation:

The given parameters are;

The mass of the block A= 58 kg

The coefficient of static friction between the block and the surface, \(\mu _s\) = 0.300

The coefficient of static friction between the rope and the fixed peg, B \(\mu _B\) = 0.310

Let T represent the tension in the rope

Therefore, when the rope is static, T = The normal reaction at the peg, B, \(N_B\)

The angle of inclination of the rope holding the block A = arctan(3/4) ≈ 36.87°

The length of the rope = √(0.4² + 0.3²) = 0.5

∴ sin(θ) = 3/5 = 0.6

cos(θ) = 4/5 = 0.8

The vertical component of the tension in the rope = T × sin(θ) = 0.6·T

The horizontal component of the tension in the rope = T × cos(θ) = 0.8·T

The friction force = μ×(W - 0.6·T) = 0.300×(58×9.8 - 0.6·T) = 170.52 - 0.18·T

The block will start to move when we have;

The horizontal component of the tension in the rope = The friction force

∴ 0.8·T = 170.52 - 0.18·T

0.8·T + 0.18·T = 170.52

0.98·T = 170.52

T = 170.52/0.98 = 174

Therefore, the tension in the rope = T = 174 N = The normal reaction at the peg, B \(N_B\)

The frictional force at the peg, \(F_B\) = \(\mu _B\) × \(N_B\) = 0.310 × 174 N = 53.94 N

The weight of the mass, \(m_c\), \(W_c\) = The frictional force at the peg, \(F_B\)  + The tension in the rope

∴ The weight of the mass, \(m_c\), \(W_c\) = 53.94 N + 174 N = 227.94 N

Weight, W = Mass, m × The acceleration due to gravity, g, from which we have;

m = W/g

Where;

g = 9.8 m/s²

∴ \(m_c\) = \(W_c\)/g = 227.94 N/(9.8 m/s²) ≈ 23.259 kg.

The greatest mass, that the weight C can have such that block A does not move = \(m_c\) ≈ 23.259 kg.

Answer:

D. Collects radiation reflected from Earth.

Explanation:

Answer:

The resulting pressure of the gas when its volume decreases is 300 kN/m².

Explanation:

Given;

initial volume of the gas, V₁ = 80 L

number of moles of the gas, n = 0.5 moles

initial pressure of the gas, P₁ = 150 kN/m² = 150 kPa

Determine the constant temperature of the gas using ideal gas equation;

PV = nRT

where;

R is ideal gas constant = 8.315 L.kPa/K.mol

T is the constant temperature

\(T = \frac{P_1V_1}{nR} \\\\T = \frac{150.kPa \ \times \ 80 .L}{0.5 .mol \ \times \ 8.315(L.kPa/mol.K)} \\\\T = 2,886.35 \ K\)

When the gas is compressed to half of its volume;

new volume of the gas, V₂ = ¹/₂ V₁

                                             = ¹/₂ x 80L = 40 L

The new pressure, P₂ is calculated as;

\(P_2V_2 = nRT\\\\P_2 = \frac{nRT}{V_2} \\\\P_2 = \frac{0.5 \times 8.315\times 2886.35}{40} \\\\P_2 = 300 \ kPa = 300 \ kN/m^2\)

Therefore, the resulting pressure of the gas when its volume decreases is 300 kN/m².

(a) A system forms an azeotrope if x1 = y1 at any given T and P. Does this system form an azeotrope at T= 308.15 K? If so, what is the composition x1 = y1 of the azeotrope? The saturation pressure of pure component 1 at T = 308.15 K is Pjat = 49.624 kPa and that of pure component 2 is Pžat = 85.265 kPa.

Now, using the following equation;P = x1Pjat + x2PžatWe can calculate the pressure of each component: 49.624 kPa = x1(49.624 kPa) + x2(85.265 kPa)Thus,x1 + x2 = 1andx1 = 0.4230.423 = 42.3%Therefore, the system forms an azeotrope at T = 308.15 K, with composition x1 = y1 = 0.423.

(b) To calculate H1, we need to use Henry's law, which is represented by the following equation:P1 = H1x1PjatUsing the value for x1 obtained from part (a) and Pjat = 49.624 kPa for component 1, we can obtain P1. We can also assume that component 1 obeys Henry's law, so we can calculate H1 by plotting P1 vs x1 and finding the slope of the line.P1 = H1x1PjatP1 = 0.423 × 49.624 kPaP1 = 21.003 kPa Hence, H1 is the slope of a plot of P1 vs x1, which gives;H1 = 0.523 kPa

The resulting reaction force at point B is equal to the normal force at point A, which is 120 N.

To determine the necessary value of the spring constant (k) and the resulting reactions at point B, we can analyze the equilibrium of forces acting on the lever ABC.

Let's consider the forces acting on the lever:

Normal Force at A:

The normal force at A is given as 120 N, acting perpendicular to the smooth surface.

Tension Force in Spring CD:

The spring CD will exert a tension force on point B of the lever. This force will be directed along the line of the spring, towards point C.

Reaction Force at B:

The reaction force at B will counterbalance the normal force at A and the tension force in the spring CD.

Since the system is in equilibrium, the sum of the forces in both the vertical and horizontal directions must be zero.

Vertical Equilibrium:

Summing the vertical forces, we have:

Reaction Force at B + Normal Force at A = 0

Reaction Force at B = Normal Force at A

Reaction Force at B = 120 N

Horizontal Equilibrium:

Since there are no horizontal forces mentioned in the problem, we can assume that the lever is in equilibrium in the horizontal direction.

Now, let's determine the necessary value of the spring constant (k):

The tension force in the spring CD can be calculated using Hooke's Law, which states that the force exerted by a spring is directly proportional to its displacement from the equilibrium position.

The unstretched length of the spring CD is given as 350 mm. Let's assume that the spring is stretched by a distance x.

The displacement of the spring from its unstretched position is given by:

x = 350 mm - 0 mm (assuming no stretching initially)

x = 350 mm = 0.35 m

Using Hooke's Law:

Tension Force in Spring CD = k * x

Since the spring exerts a tension force towards point C, we can write:

Tension Force in Spring CD = -k * x

Substituting the given values, we have:

120 N = -k * 0.35 m

To find the necessary value of the spring constant (k), we can solve for k:

k = -120 N / 0.35 m

k ≈ -342.86 N/m

The necessary value of the spring constant to exert a 120 N normal force at point A is approximately 342.86 N/m.

To exert a 120-N normal force on a smooth surface, the necessary spring constant is 342.9 N/m and the resulting reactions at point B are also 120 N.

The necessary value of the spring constant k can be determined using Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position. In this case, the force exerted by the lever ABC is the normal force, which is equal to the weight of the object. So, the normal force N is equal to 120 N. To find the spring constant, we can use the equation F = kx, where F is the force, k is the spring constant, and x is the displacement of the spring. Since Ax is given as 350 mm, or 0.35 m, we can substitute the values into the equation to find the spring constant: 120 N = k * 0.35 m. Solving for k, we get k = 120 N / 0.35 m = 342.9 N/m.

The resulting reactions at point B can be determined using Newton's third law, which states that for every action, there is an equal and opposite reaction. Since the lever ABC exerts a downward force at point A, point B exerts an equal and opposite upward force. So, the reaction at point B is also 120 N.

Answer:

Option D is correct.

The market for textbooks has a shortage. There will be an upward pressure on price, which will cause quantity demanded to fall and quantity supplied to rise.

Explanation:

The complete question is attached to this solution.

Note that

- The quantity demanded is the negative sloping line in colour blue indicating that the quantity demanded increases as the price of the commodity (textbook) falls and the quantity demanded rises as the price of the textbook falls.

- The quantity supplied is the positive sloping line in colour red/orange indicating that the quantity supplied decreases as the price of the commodity (textbook) falls and the quantity supplied increases as the price of the textbook falls.

The quantity demanded and the quantity supplied balance each other and cross path at a point called the equilibrium point.

The price at this point is called the equilibrium price and the quantity at this point is the equilibrium quantity.

For this question, the equilibrium price = $150 and the equilibrium quantity that matches quantity demanded with quantity supplied = 500.

At prices greater than the equilibrium price, the quantity demanded falls and the quantity supplied increases, hence, there is a surplus of the commodity (textbook) as the quantity of textbooks supplied is way more than the quantity demanded and there is more than required textbooks.

At prices lower than the equilibrium price, the quantity demanded increases and the quantity supplied reduces, hence, there is a shortage of commodity (textbook) as all of the goods supplied are totally bought with extra demand remaining.

When there is a surplus or shortage, the market forces that are responsible for price fixing and quantity demanded work together to take the market back to equilibrium.

So, when the price is higher than equilibrium price and there is a surplus, the market works to reduce the price of the commodity so that quantity demanded can rise and quantity supplied can fall to counter this surplus.

When the price is lower than equilibrium price and there is a shortage, the market works to increase the price of the commodity so that quantity demanded can fall and quantity supplied can rise to counter this shortage.

The price of the textbook in the question, $125, is lower than the equilibrium price, $150, hence, there will be a shortage of textbooks because the quantity demanded, at this price, is higher than the quantity that will be supplied.

So, there is then a pressure on the price to rise back so that the quantity demanded reduces and the quantity supplied increases.

To build a truth table, canonical SOP form, and simplify using Karnaugh Maps for a 4-input, 7-output binary LED display:

First, construct a truth table with 4 inputs (representing binary digits 0-9) and 7 outputs (z1 through z7) corresponding to the LED display segments. Each row in the truth table represents a binary input value (0-9), and the outputs indicate which segments of the LED display should be lit.

Next, for each output (z1 through z7), derive the canonical Sum of Products (SOP) form. The SOP form represents the logical expression in terms of the input variables. It consists of OR-ed terms where each term is an AND operation of input variables or their complements.

After obtaining the SOP form, simplify the logical expression using Karnaugh Maps. Karnaugh Maps provide a visual representation of the input-output combinations, making it easier to identify patterns and simplify the expressions.

Group adjacent 1s in the Karnaugh Map to form groups of 2, 4, or 8 cells, which can then be simplified to obtain a minimized SOP form.

For each output, analyze the simplified expression and explain why each input is eliminated in the output for each group. This analysis helps understand the relationship between the input variables and the illuminated segments of the LED display.

A net energy ratio (NER) of 0.2 implies that the energy resource in question requires a significant amount of energy to extract and produce, and that the energy output from the resource is relatively low.

This low NER suggests that the energy resource may not be a sustainable or efficient source of energy. Energy evaluators, who are responsible for assessing the viability and sustainability of energy resources, are likely to recommend against using this particular energy resource. This is because a low NER means that the energy resource is not efficient or cost-effective, and may not provide a significant energy output to meet energy demands.

Instead, energy evaluators may recommend investing in more sustainable and efficient energy resources, such as renewable energy sources like solar or wind power. These energy sources have higher NERs, meaning they provide a greater energy output relative to the energy input required for production. Additionally, renewable energy sources have a lower environmental impact compared to fossil fuels, which are often associated with high NERs.

In summary, a new energy resource with a net energy ratio of 0.2 is likely to be deemed inefficient and unsustainable by energy evaluators. As a result, investing in more sustainable and efficient energy resources, such as renewable energy sources, is recommended.
