Note that Option B - ∀x P(x) ∨¬P(x) is a valid sentence.

Option B is known as the law of the excluded middle, which states that for any proposition P, either P is true or its negation, ¬P, is true. This law holds for all values of x, so the statement ∀x P(x) ∨¬P(x) is always true.

An argument is valid if and only if it is required that if all of the premises are true, then the conclusion must be true; it is impossible that all of the premises are true and the conclusion is false. An invalid argument is one that is not legitimate.

A large fast-moving truck collides with a small stationary car. During the collision the magnitude of force on the truck is greater than the magnitude of force on the car.

When a large, fast-moving truck collides with a small, stationary car, the forces experienced by the two vehicles are unequal. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. The force exerted by the truck on the car is equal in magnitude but opposite in direction to the force exerted by the car on the truck. However, due to the significant difference in mass and size between the truck and the car, the effects of the forces on each vehicle are not the same.

In this scenario, the truck has a much larger mass and momentum than the car. When the collision occurs, the truck transfers some of its momentum to the car, resulting in a change in velocity for both vehicles. The force experienced by the car is relatively smaller compared to the force experienced by the truck due to the car's lower mass. Therefore, the magnitude of force on the truck is greater than the magnitude of force on the car.

It is important to note that the force exerted during a collision depends on various factors, including the masses and velocities of the colliding objects. In cases where the size and mass of the vehicles involved in a collision differ significantly, as in the example given, the force experienced by the smaller object will generally be less than the force experienced by the larger object.

Work, U, is equal to the force times the distance:

U = F · r

Force needed to lift the weight, is equal to the weight: F = W = m · g

so:

U = m · g · r

   = 20.4kg · 9.81 \(\frac{N}{kg}\) · 1.50m

   = 35.316 W

The car slows down and the back brake light will come on when the brake pedal is depressed.

When a car's brake pedal is depressed, braking system calipers are energized by hydraulic pressure, clamping down on the disc brake to slow or stop the car.

The master cylinder is activated when the braking system is depressed, and hydraulic fluid is then transmitted through the brake pedal to both the calipers. The calipers force the brake pads against the rotor under the pressure from the fluid, creating friction that slows or stops the vehicle.

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.

Answer:

\(I = 45mA\)

Explanation:

Given

\(I = 90mA\) --- Current

Required

Determine the new current when resistance is doubled

Using \(V = IR\)

Initially, we have:

\(V = 90mA * R\)

When resistance is doubled and voltage remains unaltered, we have:

\(V = I* 2R\)

2R represents the new resistance and I represents the new current

Equate both values of V

\(90mA * R = I* 2R\)

Make I the subject

\(I = \frac{90mA * R}{2R}\)

\(I = \frac{90mA }{2}\)

\(I = 45mA\)

The new current is 45milliAmps

When it comes to selecting a motherboard for a smaller size and lower power, the Mini-ITX form factor should be chosen.

Mini-ITX motherboards are small-sized motherboards designed to minimize the size of desktop

PCs while offering the essential features of larger motherboards.

These motherboards are around 6.7 inches square,

which makes them small enough to fit into tight spaces.

Mini-ITX motherboards are perfect for building HTPCs,

mini PCs,

and small form factor (SFF) PCs that require low power consumption.

To select a motherboard that can build a smaller PC with lower power requirements,

one should look for a motherboard that supports an energy-efficient CPU.

It's essential to check that the motherboard you choose can handle the power requirements of the CPU you want to use.

Additionally,

one should consider the number of RAM slots and the number of expansion slots on the motherboard.

If the client doesn't want to use a dedicated graphics card,

then onboard graphics should also be a factor to consider.

Mini-ITX motherboards are great for building compact PCs.

These motherboards have a smaller footprint than Micro-ATX motherboards and full-sized ATX motherboards.

Mini-ITX motherboards are ideal for building an SFF PC that can perform all the tasks that larger computers can do but in a much smaller package.

It is worth noting that when building a computer with a Mini-ITX motherboard,

one will have to compromise on expandability and features compared to larger-sized motherboards.

Thus, we can increase Xs by increasing FA0. Therefore, FA0 > 100mol/min.Also, to maximize Cs, we need to maximize the value of CA. CA = CA0*(1 - XA). Thus, CA < CA0.So, the operating condition (Xa, tau, and Cs) which maximizes Cs in a mixed flow reactor is FA0 > 100mol/min and CA < CA0.
