Explanation:

i have 8 cARS

The number of paths in the network is six.

The paths are:
C - A - T - N - EndC - A - T - R - N - EndC - B - P - U - N - EndC - B - P - U - T - R - N - EndC - B - P - A - T - N - EndC - B - P - A - T - R - N - End
2. The critical path is C - A - T - N - End with a duration of 24 weeks.

3. The float on activity U is 1 week.

4. If activity B takes three weeks longer than planned, it will affect the duration of path 3 and the entire project. It will elongate the project duration to 29 weeks.

2. b) The critical path is A-C-E-G with a duration of 18 weeks.

(c) The normal expected project completion time is 18 weeks.

(d) The total project cost using normal time is RM 7600.

(e) To complete the project two weeks faster, activities C and E can be crashed for the minimum cost.

The additional cost incurred will be RM 600.

The total cost is RM 8200.

3 The inventory cost that will minimize the total cost of inventory is obtained using the formula,

TAC = IC + OC + HCS

Where TAC

= Total Annual CostIC = Inventory CostOC = Ordering CostHCS = Holding and Carrying Cost.

The probability distribution is shown below. Demand 0 1 2 3 4 5Probability 0.20 0.15 0.25 0.20 0.10 0.10

To determine the optimal order quantity and reorder policy that would minimize total cost,

the EOQ (Economic Order Quantity) model will be used.

The EOQ can be determined using the formula,

Q = √((2DCO)/CH')

Where Q = Economic Order Quantity

D = Demand'

C0 = Cost per order

H = Holding cost

C = IC per unit

Let’s assume the cost per unit, C = RM 500,

the holding cost, H = 0.2,

and demand, D = 3 units per day.

Hence,CO = RM 800 (C0 = Cost per order, which is the same as ordering cost)

Then,Q = √((2 x 3 x RM 800)/RM 100)Q = 24 units per order

Then, the reorder level can be determined using the formula,

ROL = d * LWhere L = Lead time

ROL = 3 x 5 = 15 units

The total annual cost can be determined by substituting the values into the formula,

TAC = IC + OC + HCS

where IC = 0.5 x RM 500

= RM 250OC

= (365/EOQ) x C0OC

= (365/24) x RM 800OC

= RM 12133.33HCS

= (Q/2) x H x dHCS

= (24/2) x 0.2 x 3HCS

= RM 7.20

TAC = RM 250 + RM 12133.33 + RM 7.20TAC = RM 12390.53

Hence, the order quantity that will minimize the total cost of inventory is 24 units.

The correct answer is since the counters can more easily quantify 20 than 1, timing many oscillations reduces the likelihood of inaccuracy in respect of inertial balance.

What is the purpose of inertial balance?

To determine an object's mass using an inertial balance. This inertial balance kit is primarily intended for use in a lab experiment where mass is quantitatively measured apart from the gravitational pull of the Earth to illustrate Newton's First Law. The mass of an object in a weightless environment is frequently calculated in space missions using the same technique.

The kit consists of a frame with two platforms, one of which has holes, joined by two horizontal spring blades. Three cylinders of unknown mass with shoulders are also included; they can all be inserted into the platform's holes. One of these masses has a hole that enables it to be suspended from a ring stand or other object using string (included).

Hence, due by timing more than one oscillation, it lessens the possibility of error, in that the counters have an easier time quantifying 20 versus 1.

Answer:

In general, the choice of bridge design will depend on various factors such as the location, the environment, the length of the span, the expected traffic, the budget, and the construction time. Different types of bridges, such as beam bridges, arch bridges, suspension bridges, and cable-stayed bridges, have different strengths and weaknesses, and are suitable for different situations.

Some factors to consider when choosing a bridge design include:

Span: If the river is wide, a longer span bridge such as a suspension or cable-stayed bridge may be required.

Location: The local geology, topography, and environmental conditions may dictate the type of bridge that can be built.

Budget: Some bridge designs are more expensive than others. A beam bridge may be the most cost-effective option.

Traffic: If the bridge will carry heavy vehicles or high volumes of traffic, a stronger, more durable bridge such as a cable-stayed bridge may be required.

Ultimately, the choice of bridge design will depend on a careful evaluation of these factors and the needs of the community. It is important to consult with experts and stakeholders to ensure that the chosen design is safe, effective, and meets the requirements of the project.

Explanation:

ANSWER : PONTOON BRIDGES

OR SUSPENSION BRIDGES

PONTOON BRIDGES:

take a bunch boats or rafts

tie them together

put a path/road on top of them

if a boat can carry a truck then so can a pontoon bridge

armies use them

smaller cost & safe

SUSPENSION BRIDGES:

source of strength its flexibility to wind,gravity, physical considerations

can be made of steel

but even cheaply with rope or jute etc.

When considering the strength in terms of load-bearing capacity and versatility, truss bridges are often considered to be the strongest type of bridge. Truss bridges are made up of interconnected triangles that distribute weight evenly across the structure, making them highly resistant to bending and compression forces. They are also relatively easy to construct using simple materials such as wood or steel, which may make them a more practical option for underserved communities.

That being said, arch bridges can also be quite strong and durable, as they rely on the inherent strength of their curved shape to distribute weight. Suspension and cable-stayed bridges, on the other hand, require more advanced engineering and construction techniques, and may be less feasible for communities with limited resources. Beam bridges are typically the simplest type of bridge, but may not be as strong or versatile as truss or arch bridges.

An effective method for recursively comparing strings can be described as follows.

Initiate the algorithm.

Receive two character sequences from the user: s1 and s2.

Invoke the recursive function named isSame(s1, s2).

The isSame function would consist of:

Verify whether both s1 and s2 contain no characters. If that is the case, then indicate a positive result.

Verify whether the dimensions of s1 and s2 display contrasting values. If not, then give a false response.

Transform the opening letters of s1 and s2 into lowercase.

If the initial letters are identical:

Invoking the same function repeatedly with the substrings s1[1:] and s2[1:] is done recursively.

Provide the outcome of the operating procedure that repeats itself.

In case the initial characters are not the same, decline the statement.

Returning to the primary program:

If the evaluation of isSame returns true, output "The two strings are identical".

If isSame doesn't yield a true outcome, output the message "The strings do not match."

Terminate the computational procedure.

This methodology employs recursion for sequential comparison of individual characters in the strings, checking for equality. If there is any difference in character or the length of strings is not equal, it will result in false.

Alternatively, it produces the value of true in the event that both strings are void, signaling that a thorough comparison of all characters has been carried out.

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.

The concentration of chloride ions in the solution can be calculated by using the Nernst equation.

The Nernst equation is used to calculate the potential of an electrochemical cell under non-standard conditions. It relates the electrode potential to the concentrations of the species present in the solution.

The Nernst equation is:E = E° - (RT/nF) ln(Q)where, E is the cell potential under non-standard conditions,E° is the standard electrode potential, R is the gas constant, T is the temperature, n is the number of moles of electrons transferred, F is the Faraday constant, and Q is the reaction quotient.In this case, the standard cell potential (E°) is 0.115 V, and the measured cell potential (E) is 0.0925 V.

The reaction is given as:2AgCl(s) + 2e- → 2Ag(s) + 2Cl-(aq)We can see that n = 2 (two electrons are transferred in the reaction).The Nernst equation can be rearranged to solve for the concentration of chloride ions (Cl-) in the solution:ln(Cl-) = (E° - E)/(0.0592/n)ln(Cl-) = (0.115 - 0.0925)/(0.0592/2)ln(Cl-) = 0.378M[Cl-] = e^0.378M[Cl-] = 1.46 MTherefore, the concentration of chloride ions in the solution is 1.46 M.
