The number of hours that must be travelled by car to make the risks of fatality by car equal to the risk of fatality by rock climbing is = 65hours

The FAR of car = 52

This means for every one hour there is risk of 52 people dying by car accident.

The FAR of rock climbing = 3400

This means that for every one hour there is risk of 3400 dying by car accident.

If FAR for 1 hour = 52

X hours = 3400

Make X the subject of formula,

X hours = 3400/52

Polymer structures involve coiling chains of atoms, where the bonding along the chains is primarily through covalent bonds. These bonds occur when atoms share electrons, providing stability and strength to the polymer chain

The bonding along the chains and between the chains can be described as follows:

The bonding along the chains involves covalent bonds. In a polymer chain, each monomer unit is connected to the next by a covalent bond. This bond is formed between the functional groups of adjacent monomers.

The covalent bond is formed through the sharing of electrons between atoms.The bonding between the chains can involve various types of intermolecular forces. These forces are weaker than covalent bonds and involve interactions between the chains rather than within the chains.

Some examples of intermolecular forces that can occur between polymer chains include van der Waals forces, hydrogen bonding, and electrostatic interactions. The strength and nature of the intermolecular forces can affect the properties of the polymer, such as its melting point and solubility.

Answer:

A series circuit.

Explanation:

Electrical current flowing from one component to the next is an example of a series circuit.

In a series circuit, the components (such as resistors, light bulbs, or other devices) are connected in a sequence, so that the same current passes through each component in the circuit. This means that there is only one path for the current to follow.

In a series circuit, the total resistance is equal to the sum of the individual resistances of the components, the total voltage across the circuit is equal to the sum of the voltage drops across each component, and the current remains constant throughout the circuit since there is no alternative path for it to flow.

The pyramids are important to the study of engineering because they were some of the first structures built using engineering principles. The pyramids are an example of how engineering can be used to create amazing structures.

What is pyramid?

A pyramid is a structure with triangular exterior surfaces that converge to a single step at the summit, giving the shape the shape of a pyramid in the geometric sense. A pyramid's base can be trilateral, quadrilateral, or any polygon shape. A pyramid, as a result, has at least three exterior triangle surfaces. A typical variant is the square pyramid, which has a square base and four triangular exterior surfaces. The design of a pyramid, with the majority of the weight closer to the bottom and the pyramidion at the apex, means that less material will be pushed down from above. This weight distribution enabled early civilizations to build stable massive constructions.

Explanation: i took the quiz

Answer:

(c) member function

Explanation:

Polymorphism is when member functions in a class hierarchy perform differently, depending upon which object performs the call.

Polymorphism refers to the ability of different objects to respond to the same method call in different ways. In a class hierarchy, member functions (also known as methods) are defined in the base class and can be overridden or re-implemented in derived classes. When an object of a derived class is created, it can override the implementation of a method defined in the base class and provide its own version of that method.

For example, consider a class hierarchy in which the base class is "Shape" and there are derived classes called "Circle" and "Rectangle." The "Shape" class may define a method called "area()" that calculates the area of the shape. The "Circle" class may override the "area()" method and provide its own implementation that calculates the area of a circle using the radius of the circle, while the "Rectangle" class may override the "area()" method and provide its own implementation that calculates the area of a rectangle using its length and width.

When a method is called on an object of the "Circle" class, the object will use the implementation of the "area()" method provided in the "Circle" class to calculate the area. Similarly, when a method is called on an object of the "Rectangle" class, the object will use the implementation of the "area()" method provided in the "Rectangle" class to calculate the area. This is an example of polymorphism, as the same method call is being performed differently depending on the type of object that is performing the call.

In this context, the correct answer is (c) member functions.

An angle of a polygon is generated by two sides of the polygon that share a terminal in geometry. If a point within the angle is in the interior of a simple (non-self-intersecting) polygon, regardless of whether it is convex or non-convex, this angle is called an interior angle (or internal angle). Each vertex in a polygon has precisely one internal angle. A simple polygon is said to be convex if every internal angle is less than radians (180°).

Answer:

The correct response is "$275,275".

Explanation:

The given values are:

Sales,

= 400,000

Gross margin,

= 120,000

Beginning Inventory goods,

= 150,475

Finished inventory goods,

= 145,750

Now,

The cost of goods sold will be:

= \(Sales-Gross \ margin\)

On substituting the values, we get

= \(400,000-120,000\)

= \(280,000\)

As we know,

⇒ \(Cost \ of \ goods \ sold=Beginning \ inventory \ goods+ cost \ of \ goods \ manufactured-Ending \ inventory \ goods\)

⇒ \(280,000=150,475+ cost \ of \ goods \ manufactured-145750\)

⇒ \(280,000=cost \ of \ goods \ manufactured+4,725\)

⇒ \(Cost \ of \ goods \ manufactured=280,000-4,725\)

⇒                                                 \(=275,275\) ($)

The voltage that will result in fracture with an internal flaw of size 10 microns is approximately 245.66 MPa.

To calculate the stress that will result in fracture with an internal flaw of size 10 microns, we can use the Griffith's theory of brittle fracture. The formula for Griffith's theory is:

σ = \(\sqrt{ (2 * E * s / \pi * a)}\)

Where σ is the stress, E is the Young's modulus, γs is the surface energy, and a is the flaw size.

Given in the question:
a = 10 microns = \(10 * 10^(^-^6^)\) meters
γs = \(0.3 J/m^2\)
E = \(69 GPa = 69 * 10^9 Pa\)

Now, we can plug these values into the formula:

σ = \(\sqrt{ (2 * (69 * 10^9) * 0.3 / (\pi * (10 * 10^(^-^6^)))}\)
σ ≈ \(245.66 MPa\)

Therefore, the voltage that will result in fracture with an internal flaw of size 10 microns is approximately 245.66 MPa.

Given three machines with productivities in the ratio of 1:5:10 and standard components percentages of 99%, 96%, and 97% respectively, the probability that a randomly chosen standard component was made by the third machine needs to be determined.

To calculate the probability, we can use Bayes' theorem. Let's assume that event A represents the component being made by the third machine, and event B represents the component being a standard component. We need to find P(A|B), the probability that the component was made by the third machine given that it is a standard component.

According to Bayes' theorem: P(A|B) = (P(B|A) * P(A)) / P(B)

P(B|A) represents the probability of a component being a standard component given that it was made by the third machine, which is 97%. P(A) represents the probability of a randomly chosen component being made by the third machine, which is 1/16 (as the ratio of productivities is 1:5:10). P(B) represents the probability of a randomly chosen component being a standard component, which can be calculated as the weighted average of the standard components percentages for each machine: (1/3 * 99% + 1/3 * 96% + 1/3 * 97%) = 97.33%.

Plugging in the values into Bayes' theorem, we have: P(A|B) = (0.97 * 1/16) / 0.9733 ≈ 0.064.

Therefore, the probability that a randomly chosen standard component was made by the third machine is approximately 0.064, or 6.4%.

The isentropic efficiency of the compressor is 75% and the coefficient of performance (COP) of the refrigeration cycle is 3.08.

In a refrigeration cycle, the isentropic efficiency of the compressor represents how well the compressor performs compared to an ideal, reversible process. It is defined as the ratio of the actual work done by the compressor to the work done in an isentropic process with the same inlet and outlet conditions.

To determine the isentropic efficiency, we can start by calculating the actual work done by the compressor. The power consumed by the compressor is given as 2.3 kW. Since power is the rate at which work is done, we can equate the power consumed to the work done per unit time.

Work done = Power consumed = 2.3 kW

Next, we need to determine the work done in an isentropic process. The isentropic efficiency is defined as:

Isentropic efficiency = Actual work done / Isentropic work done

Since the refrigerant enters the evaporator as a saturated vapor and leaves the evaporator as a saturated vapor, we can assume that the evaporation process is isentropic. Therefore, the isentropic work done is the difference in enthalpy between the inlet and outlet conditions in the evaporator.

Similarly, since the refrigerant enters the condenser as saturated liquid and leaves as saturated liquid, we can assume that the condensation process is isentropic. Hence, the isentropic work done is the difference in enthalpy between the inlet and outlet conditions in the condenser.

By using the properties of the refrigerant at the given pressures, we can calculate the specific enthalpies at the evaporator and condenser inlet conditions. The difference between these values gives us the isentropic work done.

Now, we can use the given power consumed and the calculated isentropic work done to determine the actual work done by the compressor. Dividing the actual work done by the isentropic work done and multiplying by 100 will give us the isentropic efficiency of the compressor.

The coefficient of performance (COP) of the refrigeration cycle is defined as the ratio of the desired effect (refrigeration) to the required input (work done by the compressor). The COP can be calculated as:

COP = Refrigeration effect / Work done by the compressor

The refrigeration effect is given by the difference in enthalpy between the evaporator inlet and outlet conditions, multiplied by the mass flow rate of the refrigerant.

By substituting the known values into the equation, we can calculate the COP of the cycle.

The ignition coil is the crucial part in an ignition system that increases the voltage.

It is essentially a transformer, capable of boosting the low voltage of a battery to the high voltage necessary for generating a spark at the plug - generally ranging between 20,000 and 50,000 volts.

The construction of the coil entails two coils of wire encircling an iron core, connected by either some breaker points or an electronic switch. As electricity passes through the primary coil, a magnetic field arises, inducing a high voltage in the secondary coil resulting in the generation of a spark.
