To answer your question, I need the Routh table you're referring to. However, I can still provide you with a general explanation of how to determine the number of roots in the right half-plane (RHP), left half-plane (LHP), and on the imaginary axis for a given polynomial using the Routh-Hurwitz stability criterion.

1. Construct the Routh table for the given polynomial.
2. Count the number of sign changes in the first column of the table. This number represents the number of roots in the RHP.
3. Subtract the number of roots in the RHP from the total degree of the polynomial to find the number of roots in the LHP.
4. If a row of all zeros appears in the Routh table, this indicates that there are roots on the imaginary axis. To determine the exact number of these roots, replace the row of zeros with a row of auxiliary polynomial coefficients (calculated by differentiating the row above it) and then continue with the Routh table construction.

Once you have completed these steps, you will have determined the number of roots in the RHP, LHP, and on the imaginary axis for the given polynomial. If you can provide the Routh table in question, I would be happy to help you determine the number of roots in each region.

To compute the critical stress required for the propagation of an internal crack of length 0.3 mm in aluminum oxide with a specific surface energy of 0.90 j/m2 and a modulus of elasticity of 393 GPa, we can use the following equation:

Critical Stress = (2 x Specific Surface Energy x Modulus of Elasticity) / Crack Length

Plugging in our values:

Critical Stress = (2 x 0.90 j/m2 x 393 GPa) / 0.3 mm

Critical Stress = 8,760 MPa

The specific surface energy for aluminum oxide is given as 0.90 J/m2 and its modulus of elasticity is 393 GPa. We are to compute the critical stress required for the propagation of an internal crack of length 0.3 mm.

Given formulae: Tensile Stress = F/A, where F is the tensile force applied and A is the cross-sectional area of the surface upon which the force is applied Modulus of Elasticity = Tensile Stress/Strain, where strain is the ratio of the change in length of an object to the original length.

Critical Stress = σ_0 √πa/2 * Y_b

The first step is to compute the tensile stress, which is given as:

Tensile Stress = F/A

We can find the cross-sectional area using the formula for the area of a circle. This formula is given as: Area = πr^2, where r is the radius of the circle. We can find the radius of the circle as r = 0.3/2 mm = 0.15 mm = 0.00015 m. We can now compute the area of the circle as follows: Area = π(0.00015)^2 = 7.07 × 10^-8 m^2.The tensile stress is given as: Tensile Stress = F/A = σ, where F is the tensile force applied, and A is the cross-sectional area of the surface upon which the force is applied. We can rearrange the equation above to get: F = Aσ = 7.07 × 10^-8 × σThe modulus of elasticity is given as:

Modulus of Elasticity = Tensile Stress/Strain, where strain is the ratio of the change in length of an object to the original length.

We can rearrange the equation above to get: Tensile Stress = Modulus of Elasticity × Strain

Let us assume that the original length of the object is L, and the change in length of the object is ΔL, then the strain is given as: Strain = ΔL/L

The critical stress is given as: Critical Stress = σ_0 √πa/2 * Y_b . We can now use the values of the specific surface energy and the modulus of elasticity to calculate the critical stress as follows: Critical Stress = √((2 × 0.90 × 10^-6 × 393 × 10^9)/((π × 0.3 × 10^-3)/2)) = 97.2 MPa

Therefore, the critical stress required for the propagation of an internal crack of length 0.3 mm is 97.2 MPa.

b. Transfer pipets; more accurate; measuring pipets.

Explanation:

Transfer pipets can be defined as an ungraduated or graduated disposable plastic instrument which are typically used in science laboratories to transfer or deliver liquids that are small in volume (microliters) . Also, they are generally being referred to as chemical

droppers, teat pipets, eye droppers, pasteur pipets, or droppers. It is made up of an ultra-clear long, slender tube with low density polyethylene (LDPE) and an integral molded bulb. The molded bulb allows a fixed volume of the desired liquid to be dispensed (transfered) or aspirated through compression and relaxation.

Hence, transfer pipets are calibrated to deliver one fixed volume and are more accurate than measuring pipets because of its long, slender tube which limits errors.

Transfer pipets are measurement pipets since they are calibrated to provide a specific volume.

Transfer pipets have been ungraduated as well as graded disposable plastic instruments that were already commonly used during research labs to transmit as well as distribute small-volume liquids.

Combining compression as well as relaxation, the molded bulb permits a set volume of such necessary fluid material to be administered as well as inhaled.

In traffic engineering, space mean speed is higher than time mean speed. Space mean speed refers to the average speed of a vehicle in space, whereas time mean speed refers to the average speed of a vehicle in time.

Space mean speed is defined as the distance covered by a vehicle during a given time interval divided by the time interval. Space mean speed is measured in meters per second or kilometers per hour. Space mean speed is dependent on the distance traveled, which means that it is based on spatial measurements. It is unaffected by traffic lights or signal changes, which is why it is the preferred speed measure for traffic engineers. Time mean speed is defined as the total distance traveled by a vehicle divided by the total time taken to travel that distance. It is the average speed over the length of the trip, and it is expressed in kilometers per hour. Time mean speed is a function of time, which means that it is based on temporal measurements. It is heavily influenced by traffic signals, stop signs, and other traffic control devices.

In traffic engineering, space mean speed is higher than time mean speed because it is based on spatial measurements rather than temporal measurements. Time mean speed is greatly influenced by traffic control devices, whereas space mean speed is not. Traffic engineers favor space mean speed because it better reflects the actual speed of vehicles on the road.

According to Ref. 213/91, fire extinguishing equipment cannot be frozen. Fire extinguishers are essential safety devices designed to combat fires effectively. They contain pressurized agents that are specifically formulated to extinguish different types of fires. Freezing temperatures can significantly impair the functionality of fire extinguishers and render them ineffective in emergency situations.

When fire extinguishing equipment freezes, several issues can arise. First, the contents of the extinguisher may expand as they freeze, potentially leading to ruptures or leaks in the container. This can cause the extinguisher to malfunction or become hazardous when used. Second, freezing temperatures can affect the performance of the extinguishing agent itself. Certain agents, such as water-based solutions, can solidify or lose their effectiveness when exposed to extreme cold.

It is crucial to store fire extinguishers in suitable environments that are above freezing temperatures. This ensures that the equipment remains in optimal condition and is ready for immediate use during emergencies.
