Explanation:

If the museum is running short of funds, and you decide to increase revenue. An increase or decrease in the price of admission into the museum depends on the following:

1. If demand for admission into the museum is elastic there are two possible outcomes

a. An increase in the price of admission leads to a decrease in the quantity demand of admission into the museum

b. A decrease in price of admission into the museum leads to an increase in the quantity demand of admission into the museum.

This follows the law of demand which states that "the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded".

2. If the demand for admission into the museum is inelastic, then an increase in price will lead to an increase in revenue of the museum.

Therefore, before the curator increase the price of admission into the museum, he should first determine the price elasticity of demand of the museum.

I'd say number 4, number 3 looks like an exhaust valve

Since we only support 32-word searches, "velocity" and any subsequent terms were not taken into account.

When an object rotates or circles around an axis, its angular velocity is the rate at which the angle between the two bodies changes. The angle that is made by a line on one body and a line on the other in the illustration represents this displacement.

A Ferris wheel, a race car driving in circles, and a roulette ball on a wheel are a few examples of angular velocity. The object's angular velocity also serves as a representation of the object's angular displacement with respect to time.

As a vector number that indicates an object's angular speed or rotational speed as well as the axis around which it is spinning, angular velocity is defined as the rate of change of angular displacement.

Explanation:

The longitudinal modulus of elasticity of this material if the respective volume fractions of the aramid and glass fibers are 0.24 and 0.28, given the following data is 32.6 GPa.

Elasticity is defined as after the forces producing the deformation are eliminated, a material body that has been distorted has the ability to revert to its original size and shape. Metals' atomic lattices undergo size and form changes when forces are applied. When forces are removed, the lattice returns to its initial, lower energy condition. Rubbers and other polymers are elastic because stretching of polymer chains occurs when forces are applied.

Longitudinal modulus are defined as the proportion of a material's length change caused by applied force to its initial length. Young's modulus is a measurement of a material's capacity to endure changes in length when subjected to compression or tension along its length.

Thus, the longitudinal modulus of elasticity of this material if the respective volume fractions of the aramid and glass fibers are 0.24 and 0.28, given the following data is 32.6 GPa.

An access control system controls access to area restricted area or facility using physical and computer-related devices, equipment along with authentication and authorization mechanisms.

Extreme fire behavior is a dangerous and devastating phenomenon that can cause significant losses of life and property in the interface. There are several factors that contribute to this behavior, but three of the most significant ones are dry and plentiful fuels, lawns surrounding structures, and eye level wind speeds greater than 15 miles per hour (24 km/hour).

Dry and plentiful fuels are a major contributing factor as they provide the fire with a ready source of fuel to burn, allowing the fire to spread rapidly and uncontrollably. Lawns surrounding structures are another contributing factor as they can act as a bridge between the fire and the structure, allowing the fire to easily reach and ignite the building. Finally, eye level wind speeds greater than 15 miles per hour (24 km/hour) can exacerbate extreme fire behavior by providing the fire with a source of oxygen, allowing it to burn hotter and faster, and making it more difficult for firefighters to control. In addition to these factors, steady burning and an unstable atmosphere can also contribute to extreme fire behavior. It is important to take these factors into account when planning for fire safety and prevention in the interface.

To design a variable voltage source using two 15V DC supplies, a 10 kΩ potentiometer, and up to two fixed value resistors, we can use a voltage divider circuit. Here's how you can do it:

1. Connect the positive terminal of one 15V DC supply to one end of the potentiometer.
2. Connect the negative terminal of the same supply to the other end of the potentiometer.
3. Connect the wiper terminal of the potentiometer to one end of a fixed value resistor, let's say R1.
4. Connect the other end of R1 to the positive terminal of the second 15V DC supply.
5. Connect the negative terminal of the second supply to the ground.

By adjusting the potentiometer, the voltage at the wiper terminal will vary between 0V and 15V. To achieve the desired output voltage range of -8V to 2V, we need to add another fixed value resistor, let's call it R2.

6. Connect one end of R2 to the wiper terminal of the potentiometer.
7. Connect the other end of R2 to the ground.

Now, the output voltage can be calculated using the voltage divider formula:

Output Voltage = (R2 / (R1 + R2)) * Supply Voltage

To achieve an output voltage range of -8V to 2V, we need to choose appropriate values for R1 and R2. Since the supply voltage is 15V, we can calculate the required resistance values as follows:

For -8V output:
-8 = (R2 / (R1 + R2)) * 15

For 2V output:
2 = (R2 / (R1 + R2)) * 15

Solving these two equations simultaneously will give us the values of R1 and R2.

Once you have the values of R1 and R2, you can construct the circuit according to the schematic below:

[15V Supply]----[Potentiometer]----[R1]----[15V Supply]
                                  |
                                [R2]

The radial load in bearing b when the motor is stopped with zero tension in the chain is 300 lb. It is logical that the load in the bearing is higher when the motor is stopped than when it is running and putting tension in the chain due to the principle of statics.

Here's why:When the motor is running, the chain is stretched due to the tension force applied to it. This tension force counteracts the radial load on the bearings, which is why the load is lower in this scenario.On the other hand, when the motor is stopped with zero tension in the chain, the weight of the load is entirely supported by the bearings.

The radial load on the bearing is given by the formula:Radial load on bearing = (Weight of load / Number of bearings) + Axial load due to belt tensionTherefore, when the motor is stopped with zero tension in the chain, the radial load on bearing b can be calculated as follows:Radial load on bearing b = (300 lb / 2) + 0Radial load on bearing b = 150 lbHence, the radial load in bearing b when the motor is stopped with zero tension in the chain is 150 lb.

x1 = P1 / (∑ xi) P. This confirms Eq. (11.16) for a binary mixture.

By extending the same reasoning to a multicomponent mixture and using the definition of mole fraction and the ideal gas law, we have proven that xk = axi, T.PR, where the summation is over all species.

To prove the equation xk = axi, T.PR for a multicomponent mixture, where the summation is over all species, we can start with the definition of mole fraction xk:

xk = nk / n,

where nk is the number of moles of component k and n is the total number of moles in the mixture.

Now, let's consider the ideal gas law:

P V = n R T,

where P is the pressure, V is the volume, R is the ideal gas constant, and T is the temperature.

For a binary mixture, we have two components (k = 1, 2), and we can express the total pressure P as the sum of the partial pressures of each component:

P = P1 + P2.

Substituting the ideal gas law equation for each component:

P = (n1 R T / V) + (n2 R T / V) = (n1 + n2) R T / V = n R T / V,

where n = n1 + n2 is the total number of moles in the binary mixture.

Since nk = xi n, where xi is the mole fraction of component k, we can rewrite the equation as:

P = (∑ xi n) R T / V,

or

P = (∑ xi) (n R T / V) = (∑ xi) P.

Dividing both sides of the equation by P:

1 = ∑ xi.

This result confirms Eq. (11.15), which states that the sum of the mole fractions of all components in a binary mixture is equal to 1.

Furthermore, Eq. (11.16) states that the mole fraction of one component in a binary mixture is equal to its partial pressure divided by the total pressure:

x1 = P1 / P.

Since we have shown that P = (∑ xi) P, we can rewrite x1 as:

x1 = P1 / (∑ xi) P.

Multiplying both sides of the equation by (∑ xi) P:

x1 (∑ xi) P = P1,

which can be simplified to:

x1 = P1 / (∑ xi) P.

This confirms Eq. (11.16) for a binary mixture.

Answer:

\(P'=0.377hp\)

Explanation:

From the question we are told that:

Initial Temperature T_1=70 F

Final Temperature \(T_2=250pisa =114.94F\)

Efficiency \(E=75\%=0.75\)

Generally the equation for Work-done  is mathematically given by

 \(W=\int C_pT\)

 \(W=10.03(114.94-70 )+0.0184((114.94)^2-70^2 )\)

 \(W=527.21btu/ibmole\)

 \(W=11.982btu/ibm\)

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

 \(P'=\frac{0.2}{0.75}\)
