The given statement is true. A sight glass is a transparent or translucent window installed in a pipeline or vessel to visually inspect the presence, level, and characteristics of a fluid.

Explanation: When a sight glass is full of vapor, it may appear similar to when it is filled with liquid. This is because both vapor and certain liquids can be transparent or have similar optical properties. In such cases, it can be challenging to distinguish between a sight glass filled with vapor and one filled with liquid by visual observation alone.

To accurately determine whether a sight glass is filled with vapor or liquid, additional information or techniques may be required.

For example, measuring the temperature or pressure of the system, observing any condensation or evaporation occurring in the sight glass, or employing other complementary instruments or indicators can help differentiate between vapor and liquid contents.

Answer:

The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: ρ=m/V where ρ is the density, m is the mass, and V is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight.

The correct option is C. 65. Velocity is defined as the displacement of an object per unit time. It is a vector quantity since it has both magnitude and direction. The SI unit for velocity is meter per second (m/s).

An object starts from rest and travels 20 m in the first 2 s and 160 m in the next 4 s.What is to be found?We need to find the velocity (in m/s) after 7 s from the start. The given data can be represented as follows:Distance traveled in the first 2 s, s₁ = 20 m.Distance traveled in the next 4 s, s₂ = 160 m.Initial velocity, u = 0 (as the object starts from rest).Let's calculate the acceleration, a during the first 6 seconds.We know that,v = u + atHere, u = 0, v = s₁/t₁ = 20/2 = 10 m/s, t = 2 seconds.

Substituting the values, we get,10 = 0 + a × 210/a = 5 m/s² Now, using the formula,v² = u² + 2asFor the first 6 seconds,u = 0, s = s₁ + s₂ = 20 + 160 = 180 m, a = 5 m/s².Substituting the values, we get,v² = 0 + 2 × 5 × 180v² = 1800v = √(1800) ≈ 42.43 m/s Now, using the formula,v = u + atFor the next 1 second, t = 1 s (total 7 seconds).u = 0, a = 5 m/s².Substituting the values, we get,v = 0 + 5 × 1v = 5 m/s Therefore, the velocity of the object after 7 s from the start is 5 m/s.

Explanation:

Mantle convection currents cause plate movement is a true statement according to the theory of plates.

Plate Tectonics is a geological theory that explains different phenomena that occur in the earth's lithosphere.

In this theory it is established that the earth's crust is fragmented, forming a mosaic of numerous moving pieces of different sizes called plates, which fit together and vary in thickness according to their composition, whether it is the oceanic, continental, or mixed crust.

Additionally, in this theory, it is established that the movement of the plates is due to the convective currents of the earth's mantle.

The radiant power absorbed by the blackened vane is 3.6 x 10^(-5) W. The radiant power incident on each vane can be calculated by multiplying the intensity by the area of the vane. The area of each vane is 0.01 m * 0.01 m = 0.0001 m^2. Therefore, the radiant power incident on each vane is 300 W/m^2 * 0.0001 m^2 = 0.03 W.

Since the silvered vane reflects all incident radiant energy, it does not absorb any power. Therefore, the total radiant power absorbed by the blackened vane is equal to the total incident power minus the reflected power. So, the radiant power absorbed by the blackened vane is 0.03 W - 0 W = 0.03 W.

However, in the question, the distance of the center of each vane from the axis is given as 6 cm, which means that the distance from the center of each vane to the axis is 0.06 m. The radiant power absorbed by the blackened vane is proportional to the distance squared, so we need to adjust the value. Since the distance of the center of each vane is six times greater than the distance given in the question, the radiant power absorbed by the blackened vane will be 0.03 W / (6^2) = 3.6 x 10^(-5) W.

Using digital equipment in metrology and regulatory standards has long-term benefits, such as increased accuracy, and efficiency. However, it also entails potential consequences, including the need for skilled technicians, cybersecurity risks, and the possibility of technological obsolescence.

The adoption of digital equipment in metrology and regulatory standards has revolutionized the way measurements and standards are established and maintained. Digital instruments offer several benefits over traditional analog equipment. Firstly, they provide higher levels of accuracy and precision, ensuring more reliable and consistent measurements. Digital systems are less prone to human error and offer enhanced resolution, making them indispensable in industries that demand precise measurements, such as manufacturing, healthcare, and scientific research.

Secondly, digital equipment improves efficiency by automating processes and reducing manual labor. With digital systems, measurements can be obtained quickly and easily, often with minimal human intervention. This not only saves time but also increases productivity, allowing for faster decision-making and improved workflow.

Furthermore, digital equipment enables efficient data management and analysis. By storing measurement data digitally, it becomes easier to organize, retrieve, and analyze large volumes of information. This facilitates better quality control, traceability, and compliance with regulatory standards. Digital systems also provide opportunities for remote access and real-time monitoring, allowing for prompt intervention and adjustments if any deviations occur.

In conclusion, the use of digital equipment in metrology and regulatory standards offers long-term benefits such as increased accuracy, improved efficiency, and enhanced data management capabilities. These advancements contribute to higher quality standards, improved productivity, and greater precision in various industries. Embracing digital technologies in metrology and regulatory practices is crucial for staying competitive and ensuring compliance with evolving standards.

However, there are also potential consequences to consider. The adoption of digital equipment requires trained technicians who possess the skills and knowledge to operate and maintain the equipment properly. Without skilled personnel, the full benefits of digital systems may not be realized.

Another concern is cybersecurity. Digital equipment is vulnerable to hacking and data breaches, posing risks to the integrity and confidentiality of sensitive information. It is crucial to implement robust cybersecurity measures and regularly update security protocols to mitigate these risks.

Moreover, the rapid pace of technological advancements means that digital equipment can become obsolete relatively quickly. Regular upgrades and investments in new technologies may be necessary to ensure compatibility with evolving standards and practices.

In conclusion, using digital equipment in metrology and regulatory standards brings long-term benefits such as increased accuracy, efficiency, and data management capabilities. However, it is important to address potential consequences such as the need for skilled technicians, cybersecurity risks, and technological obsolescence to maximize the advantages and mitigate risks associated with digitalization.

Explanation:

newtons first law is inertia his second is acceleration and third is interactive.

The axial resistance of an axon is calculated using the formula R = ρL/A, where ρ is the resistivity, L is the length, and A is the cross-sectional area. In this case, the axial resistance is 11.28 MΩ.

The resistance along the axon is calculated using the following formula:

R = ρL/A

where:

R is the resistance in ohms

ρ is the resistivity in ohms per meter

L is the length in meters

A is the cross-sectional area in meters squared

In this case, we have:

ρ = 1.6 x 107 Ω.m

L = 0.5 mm = 0.0005 m

A = πr² = π(5 x 10-6)² = 7.854 x 10-13 m²

Therefore, the resistance is:

R = ρL/A = (1.6 x 107 Ω.m)(0.0005 m) / (7.854 x 10-13 m²) = 11.28 MΩ

Therefore, the axial resistance of the axon is 11.28 MΩ.
