The statement is true because MRI (magnetic resonance imaging) uses a strong magnetic field, radio waves, and a computer to produce detailed images of the body.

Unlike X-rays, which use ionizing radiation, MRI uses non-ionizing radiation. The magnetic field generated by the MRI machine aligns hydrogen atoms in the body, and then the radio waves cause the atoms to emit signals that are detected by the machine and turned into images.

MRI is particularly useful for soft tissue imaging, such as the brain, spine, and joints, where X-rays would not provide enough detail. Additionally, MRI can show the difference between normal and abnormal tissue, making it a valuable tool for diagnosing a variety of medical conditions.

c. the U.S. Constitution.

Explanation:

A Constitution refers to a set of written laws and principles which is typically used to determine the power and authority of the government, as well as guarantee the fundamental rights of its citizens.

Basically, the Constitution accords powers to the national or federal government and these includes; enumerated or delegated, reflected, and concurrent powers. Therefore, base on the US Constitution, any law, act, or license issued and approved by the federal government supercedes or overrides any state law.

In this scenario, NatGas Corporation obtains a federal license to operate a gas pipeline through a certain area of Oregon. The Oregon state legislature enacts a law that bans gas pipelines in that area. Most likely, the state law violates the U.S. Constitution because a federal law is supreme.

The statement "In a regular pyramid, the slant height is always longer than a lateral edge of the pyramid" is false.

In a regular pyramid, the slant height refers to the distance from the apex (top) of the pyramid to any point on the lateral face, measured along the slanted surface. A lateral edge, on the other hand, refers to the length of an edge that connects the apex to a vertex of the base.

In a regular pyramid, the slant height and the lateral edge are typically not equal to each other. The slant height is generally longer than a lateral edge. This can be understood by considering the shape of a regular pyramid, where the slant height forms a diagonal along the lateral face, while the lateral edge is a straight line connecting the apex and a vertex of the base.

However, it is important to note that the specific lengths of the slant height and lateral edge depend on the dimensions of the pyramid, such as the base size and the height. The relationship between the slant height and lateral edge can vary depending on the specific measurements of the regular pyramid.

FDM is a manufacturing process that creates objects layer by layer by depositing molten thermoplastic material.

The length of time it takes to create a four-colored ball with a diameter using FDM is determined by a variety of variables.

These variables are layer thickness, nozzle width, extrudate deposition rate, stage movement time per layer, and the time it takes to change between any two materials.

The ball's construction time can be calculated using these variables.

The following formula can be used to calculate the ball's production time:

Volume of Sphere = 4/3 * pi * r³

Volume of the sphere = 4/3 x pi x 2²³

Volume of the sphere = 33.51 cm³

The total volume of the ball will be 33.51 cm³.

We'll use this to figure out how long it will take to manufacture this ball.

We can use the following formula:

Time = (Layer height x Layer width x 60) / Extrudate Deposition Rate x Stage Movement Time x Fill ratio x Volume of sphere

Time = (0.15 x 0.4 x 60) / 6 x 1 x 0.3 x 33.51The time it takes to fabricate the ball is calculated as follows:

Time = 5.13 hours or 308 minutes

it will take around 308 minutes to fabricate a 4 colored ball in diameter using FDM,

assuming a layer thickness of 0.15mm, a width of 0.4mm, and the extrudate being deposited at a rate of 6 cubic mm per second.

Additionally, it is supposed that the stage movement time is 1 minute per layer, and it takes 1 minute to switch between any two materials.

Finally, assume the support structure has a volumetric fill ratio of 30%.

a) the repeat unit molecular weight of PTFE MW = 100.015 g/mole

b) the number-average molecular weight for a PTFE for which the degree of polymerization is 10,000 щₙ = 1000150 g/mole

Explanation:

Given that;

PTFE which is also called Polytetrafluoroethylene

structure  of repeat unit of Polytetrafluoroethylene

(C2F4)n

a)

To compute the repeat unit molecular weight

we say

MW = 2( atomic weight of C ) + 4( atomic weight of F)

MW = 2 (12.0107) + 4 ( 18.9984)

MW = 100.015 g/mole

therefore the repeat unit molecular weight of PTFE MW = 100.015 g/mole

b)

To compute the number-average molecular weight for  PTFE of which the degree of polymerization is 10,000

we say

DP = щₙ / MW

where щₙ is the number of average molecular weight,

MW is the repeat unit molecular weight give as 100.015 g/mole

DP is degree of polymerization which is 10,000

Now we substitute

10,000 = щₙ / 100.015

щₙ = 10,000 × 100.015

щₙ = 1000150 g/mole

Therefore the number-average molecular weight for a PTFE for which the degree of polymerization is 10,000 щₙ = 1000150 g/mole

A: Daisy-chaining hubs can cause issues with addressing data for its proper destination. As the number of hubs in the chain increases, the network becomes more complex, and it becomes more difficult for the network to properly route data packets to their intended destinations.C: Each hub in the chain adds a certain amount of attenuation to the data signal. As the number of hubs in the chain increases, so does the amount of attenuation. This can eventually result in signal degradation and data loss.B: Each segment of a 100Base-T network is limited to a maximum length of 100 meters.

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

Now, the modulus of elasticity (E) is given as:

\(E = \frac{\sigma}{\epsilon}\\\\E = \frac{6.62\ kips}{7.5\ x\ 10^{-4}}\)

E = 8.83 kips

Fine grained of alkali igneous rocks cannot be used in cement because of the volume expansion caused by the Alkali-silica reaction, fine-grained igneous rocks cannot be used as aggregates in cement.

Extrusive igneous rocks have a fine-grained or aphanitic texture, with grains that are too small to see without a magnifying glass. The fine-grained texture suggests that the rapidly cooling lava did not have enough time to form large crystals. A petrographic microscope can be used to examine these tiny crystals.

The texture of an igneous rock (fine-grained vs coarse-grained) is determined by the rate at which the melt cools: slow cooling produces large crystals, while fast cooling produces small crystals.

The chemical reaction that occurs in both alkali cations and hydroxyl ions in the pore solution of hydrated cement paste and certain reactive silica phases present in concrete aggregates is known as the alkali-silica reaction (ASR).

To calculate the change in width of the square metal bar, we need to use the Poisson's ratio (ν) and the axial strain formula. Here are the given values:

Length = 6 m
Width = 9 mm
Axial tensile force = 2,095 kN
E = 110 GPa
ν = 0.34

First, calculate the cross-sectional area of the bar (A):
A = width² = (9 mm)² = 81 mm²
Next, convert the axial tensile force to Newtons and calculate the axial stress (σ):
Force = 2,095 kN * 1000 N/kN = 2,095,000 N
σ = Force / A = 2,095,000 N / 81 mm² ≈ 25,864 N/mm²
Now, calculate the axial strain (ε):
ε = σ / E = 25,864 N/mm² / 110,000 N/mm² ≈ 0.000235

Next, find the lateral strain (ε_L) using Poisson's ratio:
ε_L = -ν * ε = -0.34 * 0.000235 ≈ -0.00008
Finally, calculate the change in width (Δw) using the lateral strain:
Δw = ε_L * initial width = -0.00008 * 9 mm ≈ -0.00072 mm

Since we need to enter a positive value for the answer, the change in width is approximately 0.00072 mm.
