The type of check that is used to determine whether the wires in a cable are good is known as a continuity check.

This type of check involves verifying that there is an uninterrupted path between two points in a circuit, which is typically done by testing the resistance between two points in the circuit.
To perform a continuity check, you will need a multimeter, which is a device that can measure voltage, current, and resistance in electrical circuits. First, you will need to set the multimeter to the continuity setting, which is typically represented by a symbol that looks like a sound wave. Next, you will need to touch the two probes of the multimeter to the two ends of the wire you are testing. If the wire is continuous and in good condition, you should hear a tone or see a light on the multimeter, indicating that there is a complete path for current to flow through the wire. If there is no tone or light, this means that there is a break or damage in the wire, and it will need to be repaired or replaced.
In summary, a continuity check is used to determine whether the wires in a cable are good by testing the resistance between two points in the circuit. This can be done using a multimeter, which will indicate whether there is a complete path for current to flow through the wire.

The correct answer is "no," because there is a loss of kinetic energy in the collision, so it is inelastic. In an inelastic collision, kinetic energy is not conserved, and some of it is converted into other forms of energy, such as heat or deformation.

A collision refers to an event where two or more objects come into contact with each other, resulting in a change in their motion or properties. Collisions can occur between objects of various sizes and in different contexts, such as physics, engineering, sports, or everyday life.  In an elastic collision, the total kinetic energy of the system is conserved before and after the collision.

As the temperature of the material increases, the potential energy of the molecules increases. Thermal expansion occurs due to changes in temperature, and interatomic distances increase as potential energy increases.

Thermal expansion is used in a variety of applications such as rail buckling, engine coolant, mercury thermometers, joint expansion, and others.

It is to be noted that an application of the concept of liquid expansion in everyday life concerns liquid thermometers. As the heat rises, the mercury or alcohol in the thermometer tube moves in only one direction. As the heat decreases, the liquid moves back smoothly.

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.

a. To modify the quadratic probing algorithm to insert an item into the first inactive cell on the search path, we need to make a change to the insert() function. The new insert() function should follow the steps given below:

1. Calculate the hash value for the new item.
2. If the hash table has an empty cell at that position, insert the new item there.
3. If the cell is marked as deleted, insert the new item there.
4. If the cell is occupied, start probing by adding 1, 3, 5, 7... to the hash value and calculate new positions. Check each position in turn, and if it is empty or marked as deleted, insert the new item there.

b. The revised algorithm is faster than the original algorithm when there are many deleted cells in the hash table, as it allows us to reclaim these cells instead of having to probe further. However, it can be slower when the hash table is almost full and there are no deleted cells available for reuse. In this case, the revised algorithm will have to probe more and may take more time than the original algorithm. It is important to note that the revised algorithm saves space by reusing deleted cells, but this may come at the cost of slower performance in certain situations.

Modern petrol engines employ ignition coils in all ignition systems for the same fundamental purpose: to produce the high voltage necessary to ignite a spark at the spark plug.

An electric spark is used in a gasoline engine's ignition system to start the fuel-air combination, which burns in the cylinders to create the motive force.

A storage battery, an induction coil, a device to timing high-voltage discharges from the induction coil, a distributor, and a set of spark plugs are the essential parts of the ignition system. The mechanism converts the low voltage electric current from the storage battery, which is typically 12 volts, to high voltage (some 40,000 volts). The distributor sends the high-voltage pulses in succession to each spark plug in the firing order.

Answer:

The minimum diameter to withstand such tensile strength is 22.568 mm.

Explanation:

The allow is experimenting an axial load, so that stress formula for cylidrical sample is:

\(\sigma = \frac{P}{A_{c}}\)

\(\sigma = \frac{4\cdot P}{\pi \cdot D^{2}}\)

Where:

\(\sigma\) - Normal stress, measured in kilopascals.

\(P\) - Axial load, measured in kilonewtons.

\(A_{c}\) - Cross section area, measured in square meters.

\(D\) - Diameter, measured in meters.

Given that \(\sigma = 75\times 10^{3}\,kPa\) and \(P = 30\,kN\), diameter is now cleared and computed at last:

\(D^{2} = \frac{4\cdot P}{\pi \cdot \sigma}\)

\(D = 2\sqrt{\frac{P}{\pi \cdot \sigma} }\)

\(D = 2 \sqrt{\frac{30\,kN}{\pi \cdot (75\times 10^{3}\,kPa)} }\)

\(D = 0.0225\,m\)

\(D = 22.568\,mm\)

The minimum diameter to withstand such tensile strength is 22.568 mm.

The conductor size, fuse, or circuit breaker size, and overload size are generally determined using the National Electrical Code (NEC).

National Electrical Code is a guidebook, which is a national standard published by the National Fire Protection Association (NFPA), that provides guidelines for the safe installation of electrical wiring and equipment in homes, buildings, and other facilities.

The NEC provides guidelines for wire ampacity, overcurrent protection, and maximum circuit length, among other things. The conductor size is determined by the load current, the maximum circuit length, and the conductor temperature rating.

The maximum circuit length is determined by the voltage drop, the load current, and the conductor size.Fuse and circuit breaker sizes are determined based on the current-carrying capacity of the conductor. They must be properly sized to protect the conductor from overcurrent, but not so small that they trip unnecessarily.The overload size is determined based on the load current.

Overload protection is a type of overcurrent protection that protects equipment from overheating and burning out due to excessive current. It is usually provided by thermal overload relays or electronic overload relays, which detect excessive current and disconnect the power source to the equipment.

\(percentage\ yield = \frac{Actual\ yield}{expected\ yield} \times 100\\Actual\ yield = 10.08kg\\Expected\ yield= 16.00kg\\\\\therefore percentage\ yield = \frac{10.08}{16.00} \times 100 = 63 \%\)

False. The most directly applicable timer to use in this scenario would be an off-delay timer, not an on-delay timer.

An on-delay timer is used to introduce a delay before an output or action is activated after the input signal is received. In this case, the lamp should be switched on once the piping system has sustained a cumulative overpressure of 60 s. Therefore, an on-delay timer would not be suitable because it would introduce a delay before activating the lamp, which is not what is required.

On the other hand, an off-delay timer is used to introduce a delay before deactivating the output or action after the input signal is removed. In this scenario, the lamp should be switched on immediately when the cumulative overpressure of 60 s is reached. Therefore, once the overpressure condition is no longer sustained, the off-delay timer would start its timing function, and when the preset time period elapses, it would switch off the lamp, maintaining it illuminated for the specified duration.

Therefore, the most directly applicable timer to use in this case would be an off-delay non-retentive timer.

To find the offset at the PVT (point of vertical tangency) of a 600-ft long equal-tangent vertical curve connecting an initial grade of 1.2% and a final grade of -1.08%, you can use the following formula:

\( \rm \: Offset \: at \: PVT = ( \frac{L}{2} ) \times \frac{(E1 + E2)}{100}\)

Where:

L = Length of the curve = 600 ft

E1 = Initial grade = 1.2%

E2 = Final grade = -1.08%

Substituting the given values into the formula, we get:

\( \rm \: Offset \: at \: PVT = \frac{600}{2} \times \frac{(1.2 - 1.08)}{100}\)

\( \rm \: Offset \: at \: PVT = 300 \times 0.012\)
