T/F : The INTERSECT set operator only displays the rows returned by both queries.

Answer:

(a) k = 0.09 s⁻¹

(b) The velocity= ± 16.97 mm/s

Explanation:

(a) Given that the acceleration = a = k(100 - x)

Therefore;

\(a = \dfrac{dv}{dt} = \dfrac{dv}{dx} \times \dfrac{dx}{dt} = \dfrac{dv}{dx} \times v = k(100 - x)\)

When x = 40 mm, v = 0 mm/s hence;

\(\int\limits^v_0 {v } \, dv = \int\limits^x_{40} {k(100 - x)} \, dx\)

\(\dfrac{1}{2} v^2 = k \cdot \left [100\cdot x-\frac{1}{2}\cdot x^{2} \right ]_{x}^{40}\)

\(\dfrac{1}{2} v^2 = -\dfrac{ k\cdot \left (x^{2}-200\cdot x+6400 \right ) }{2}\)

At x = 100 mm, v = 18 mm/s hence we have;

\(\dfrac{1}{2} 18^2 = -\dfrac{ k\cdot \left (100^{2}-200\times 100+6400 \right ) }{2} = 1800\cdot k\)

\(\dfrac{1}{2} 18^2 =162 = 1800\cdot k\)

k = 162/1800 = 9/100 = 0.09 s⁻¹

(b) When x = 120 mm, we have

\(\dfrac{1}{2} v^2 = -\dfrac{ 0.09\times \left (120^{2}-200\times 120+6400 \right ) }{2} = 144\)

Therefore;

v² = 2 × 144 = 288

The velocity, v = √288 = ±12·√2 = ± 16.97 mm/s.

Answer:

To find the stress you need to know the applied load. Without that information, it is not possible to determine the axial stress in each of the three rods.

Explanation:

To determine the axial stress in each of the three rods, you would need to know the applied load and the cross-sectional area of each rod. The formula for axial stress is:

Stress (σ) = Load (F) / Area (A)

The area of a rod can be determined using the formula:

Area = π * (diameter/2)^2

Where diameter is the diameter of the rod in inches.

So,

For rod 1(aluminum rod)

Area = π * (2.00/2)^2 = 3.14 in^2

For rod 2(brass rod)

Area = π * (1.50/2)^2 = 1.77 in^2

For rod 3(steel rod)

Area = π * (3.00/2)^2 = 7.07 in^2

To find the stress you need to know the applied load. Without that information, it is not possible to determine the axial stress in each of the three rods.

Explanation:

The forward-biased voltage drop of a semiconductor diode depends on the material it is made of and the method of fabricating the junction.

A silicon diode will have a voltage drop that can be estimated as 0.7 V. The actual value will depend on current and temperature.

A germanium diode will have a voltage drop closer to 0.3 V, again depending on current and temperature.

A Schottky diode may have a voltage drop between 0.2 and 0.3 V, so may be difficult to distinguish from a germanium diode.

If it measures 0.3 V, the diode is probably made of germanium, and is forward biased.

__

The reverse-biased voltage reading will generally match the open-circuit voltage of the testing device.

It does not seem reasonable to expect a tensile stress of 200 MPa to produce a reduction in specimen diameter of 0.08 mm

Given data :

Diameter ( d ) = 10 mm

length ( l ) = 150 mm

elasticity ( ∈ ) = 100 GPa

longitudinal strain ( б ) 200 MPa

Poisson ratio ( μ )  ( assumed ) =0.3

Assumption : deformation totally elastic

Answer:

Rate of Heat Loss = 336 W

Explanation:

First, we will find the surface area of the cylinder that is modelled as the man:

\(Area = A = (2\pi r)(l)\)

where,

r = radius of cylinder = 30 cm/2 = 15 cm = 0.15 m

l = length of cylinder = 170 cm = 1.7 m

Therefore,

\(A = 2\pi(0.15\ m)(1.7\ m)\\A = 1.6\ m^2\)

Now, we will calculate the rate of heat loss:

\(Rate\ of\ Heat\ Loss = hA\Delta T\)

where,

h = convective heat tranfer  coefficient = 15 W/m²K

ΔT = Temperature difference = 34°C - 20°C = 14°C

Therefore,

\(Rate\ of\ Heat\ Loss = (15\ W/m^2K)(1.6\ m^2)(14\ K)\\\)

Rate of Heat Loss = 336 W

At amateur operating frequencies, the FTDX10 is designed for 50 Ohm resistive impedance.

Impedance is the sum of resistance and reactance. It was defined as anything that can obstructs the flow of electrons within the electrical circuit. As a result, it influences current generation in the electrical circuit. It could be found in all the possible circuit components and across all possible electrical circuits. Impedance is represented mathematically by the letter Z and has the unit ohm. It's a mix of resistance and reactance.

Z stands for impedance, which is an expression of the resistance to alternating and/or direct electric current that an electronic component, circuit, or system offers. Resistance and reactance are two independent scalar (one-dimensional) phenomena that make up the vector (two-dimensional) quantity known as impedance.

If a chemical were added to mitochondria that allows protons to freely cross the inner mitochondrial membrane, ATP production by oxidative phosphorylation would decrease.

The mitochondrial electron transport chain produces ATP by pumping protons from the mitochondrial matrix to the intermembrane space, creating a proton gradient. This gradient is then used by ATP synthase to produce ATP by oxidative phosphorylation. If a chemical were added to the mitochondria that allows protons to freely cross the inner mitochondrial membrane, the proton gradient would be disrupted, and ATP production would decrease. This is because the proton gradient is necessary for ATP synthesis, and if protons can move freely across the membrane, the gradient would dissipate, and less ATP would be produced.

The correct answer choice for implementing the enqueue() method in a queue with a linked list in Java is append().

When implementing a queue using a linked list, the enqueue operation adds an element to the end of the list, as it follows the FIFO (First-In-First-Out) principle. The append() method in the linked list class would typically be used to add a new element at the end of the list, making it the most appropriate choice for the enqueue operation.

The other answer choices are not directly related to the enqueue operation in a queue implementation using a linked list:

removeafter() is used to remove an element after a specified node, which is not necessary for the enqueue operation.

prepend() is used to add an element at the beginning of the list, which does not follow the FIFO principle of a queue.

insertafter() is used to insert an element after a specified node, but it is not typically used in the enqueue operation of a queue.

The average number of aircraft on the runway at the airport is approximately 12. The correct option is B

Since the average time spent between leaving the gate and taking off is 4 minutes, and an aircraft takes off every 0.67 minutes, we can conclude that the average number of aircraft on the runway during this time is 4 minutes / 0.67 minutes per take-off = 5.97 aircraft.

Similarly, the average number of aircraft on the runway during the time between landing and reaching their gate is also 5.97 aircraft.

Therefore, the average number of aircraft on the runway at the airport is the sum of these two values:

Average number of aircraft on the runway = 5.97 + 5.97
