Answer:

d.

Explanation:

The synchronous speed (Ns) of a motor with 4 poles and operating at a frequency of 60Hz can be calculated using the formula:

Ns = 120 x f / p

where f is the frequency in Hertz and p is the number of poles.

Plugging in the values, we get:

Ns = 120 x 60 / 4 = 1,800 rpm

Therefore, the answer is option d) 1,800 rpm.

As you operate successively more devices in a circuit, the current increases and the voltage decreases.

When devices are connected in series in a circuit, the current remains the same throughout the circuit. Therefore, as more devices are added in series, the current flowing through each device will increase. This is because the total current flowing in the circuit needs to pass through each device.

On the other hand, when devices are connected in parallel in a circuit, the voltage across each device remains the same. As more devices are added in parallel, the total current flowing in the circuit increases. According to Ohm's law (V = IR), if the current increases while the resistance (or impedance) remains constant, the voltage across the devices will decrease to maintain a consistent current flow.

It's important to note that these relationships hold true under ideal conditions and assumptions, such as fixed resistance values and a constant power supply. Real-world circuits may have additional factors and limitations that could affect these relationships.

To determine the average number of workers at the trailer, we can use the M/M/1 queuing model, where arrivals follow a Poisson process and service times follow an exponential distribution.So, the correct answer is:2 workers

Given that workers arrive at an average rate of 8 per hour, the arrival rate (λ) is 8 per hour. The average service time (1/μ) is 6 minutes, which can be converted to hours by dividing by 60, resulting in μ = 1/10 per hour.

Using the M/M/1 queuing formula for the average number of workers (N) in the system:

N = λ / (μ - λ)

Substituting the values, we have:

N = 8 / (1/10 - 8) = 8 / (1/10 - 80) = 8 / (-79/10) = -80/79 ≈ -1.01

Since the number of workers cannot be negative, we take the absolute value, resulting in approximately 1.01 workers.

However, since the question asks for the average number of workers at the trailer, including the one whose permit is being worked on, we need to consider at least one worker. Therefore, we round up the result to the nearest whole number, which gives us an average of 2 workers at the trailer.

If we tried to further accelerate a Supersonic fluid with a diverging diffuser,  the pressure will decrease due to an increase in area. This can be described as :

dA/A = dP/ρV² (1-M²) for supersonic flow Mach Number, M: M > 11 - M² < 0 (dA/A) = -K (dP/ρV²)k = 1-M²

Supersonic flow fields have Mach numbers greater than one at every location. Supersonic flows are usually characterized by the presence of shock waves, which cause abrupt changes in flow characteristics and streamlines (in contrast to the smooth, continuous variations in subsonic flows).

Supersonic and subsonic relate to speeds that are faster or slower than the speed of sound, respectively. Supersonic means traveling faster than the speed of sound, which is 343.2 m/s (1,126 ft/s). Subsonic speeds are defined as anything moving slower than the speed of sound.

In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

Explanation:

The power transmitted by the belt in a belt sander can be calculated using the formula P = F * V, where P is power, F is the force, and V is the velocity. Therefore, by applying the given values and calculations, we can determine the power transmitted by the belt in Btu/s and hp, as well as the work done in one minute of sanding in Btu.

In this case, the downward force on the sander is given as 15 bf (pound-force) and the belt speed is 1500 ft/min. The coefficient of friction between the sander and the plywood is 0.2. To calculate the power transmitted by the belt, we use the formula P = F * V, where P is power, F is the force, and V is the velocity. Substituting the given values, we have P = 15 bf * 1500 ft/min.

To convert the power from British thermal units per second (Btu/s) to horsepower (hp), we need to use the conversion factor of 1 hp = 2544 Btu/s. So, we divide the power in Btu/s by 2544 to get the power in horsepower.

To determine the work done in one minute of sanding, we multiply the power by the time. Since the time given is in minutes and the power is in Btu/s, we need to convert the time to seconds before performing the calculation. Finally, the work done can be expressed in Btu.

Explanation:

The vander waals equation

\((P+n^2a/V^2)(V-nb)\)=nRT

The factor n^2a/V^2 accounts for the attractive forces between the gases molecules whereas nb accounts for the decrease in volume occupied by the gas. Therefore, correct option would be  E. None of the above have BOTH of the two factors accurately stated

The correction of Van Der Waal to the ideal gas equation is that; real gas molecules exert forces on each other and that gas molecules have volume.

Van Der Waal (1873) proposed a modification to the ideal gas equation; PV = nRT. The ideal gas law assumes that molecules of gases do not have a definite volume but occupies the same volume as the container and do not exert any attractive forces on each other.

However, Van Der Waal introduced two major corrections to the ideal gas equation;

Hence, the ideal gas equation is now written as;

The corresponding wavelength emitted by the hydrogen-like li²⁺ ion for the same transition must be 1/9th of 656 nm photons.

A waveform signal's wavelength is defined as the separation between two identical points (adjacent crests) in adjacent cycles as the signal travels through space or along a wire. This length in wireless systems is typically specified in meters (m), centimeters (cm), or millimeters (mm) (mm).

It is more common to specify the wavelength in nanometers (nm), which are units of 10-9 m, or angstroms (), which are units of 10-10 m, for infrared (IR), visible light (VL), ultraviolet (UV), and gamma radiation (). Frequency, or the quantity of wave cycles per second, is inversely related to wavelength. The wavelength of a signal decreases in length as its frequency increases.

b. American Society of Mechanical Engineers

Explanation:

The "American Society of Mechanical Engineers" (ASME) is an organization that ensures the development of engineering fields. It is an accreditation organization that ensures parties will comply to the ASME Boiler and Pressure Vessel Code or BPVC.

The BPVC is a standard being followed by ASME in order to regulate the different pressure vessels and valves. Such standard prevents boiler explosion incidents.

The engineer's data on the number of failures in each mode for each of the three configurations can be used to determine whether the configuration has an effect on the type of failure.

To analyze this data, statistical methods can be employed to identify any significant differences between the failure modes in each configuration. One approach to this analysis is to use a chi-square test of independence. This statistical test can determine whether there is a significant association between two categorical variables, in this case the configuration and the failure mode. If the p-value of the test is below a predetermined level of significance (usually 0.05), then there is evidence that the configuration has an effect on the type of failure. Another approach to analyzing this data is to use a contingency table to display the frequency of failures in each configuration and failure mode. This can help identify any patterns or trends in the data, which can provide insights into the effects of the different configurations on the type of failure.

Overall, it is possible to determine whether the configuration has an effect on the type of failure by analyzing the data obtained by the engineer. By using statistical methods and contingency tables, it is possible to identify any significant associations or patterns in the data, which can help engineers make informed decisions about the design of the component.
