Note that the internal device has the largest nonvolatile storage capacity s: "Hard Drive" (Option A)

Non-volatile memory, often known as non-volatile storage, is a type of computer memory that can preserve data long when power is turned off. In contrast, volatile memory requires constant power to maintain data.

Non-volatile memory (NVM) is a form of computer memory that can store data even when the power is switched off. Unlike volatile memory, NVM does not require its memory data to be updated on a regular basis. It is widely utilized for secondary storage as well as long-term constant storage.

The pressure at the top of the hill is 569.94 kPa and 82.638 psi. A barometer is a measuring device used to measure atmospheric pressure.

A mercury barometer's standard atmospheric pressure reading is 760 mm of mercury (Hg). The reading of the barometer is 65 cm of Hg at the top of the hill. In order to express the reading of the barometer in kPa and psi, we can use the following conversion factors:1 atm = 101.325 kPa1 atm = 14.696 psi The pressure at the top of the hill is:65 cm of Hg = 65/100 m of Hg The density of mercury is 13.6 g/cm³, so the mass of mercury supported by a 1 cm² column is 13.6 g. As a result, a 65/100 m of Hg column has a mass of 13.6 * 65/1000 = 0.884 g/cm².So, at the top of the hill:Pressure in Pa = density of mercury * gravity * height of columnPressure in Pa = 0.884 * 9.8 * 65/100Pressure in Pa = 569.936 Pa = 569.94 kPa (rounded to 3 decimal places)To calculate the pressure in psi,Pressure in psi = 569.94 kPa / 6.8948 psiPressure in psi = 82.638 psi (rounded to 3 decimal places)Therefore, the pressure at the top of the hill is 569.94 kPa and 82.638 psi.

True. As dislocation density increases, the resistance to dislocation movement increases. This is because a higher density of dislocations leads to more interactions and entanglements between them, making it more difficult for the dislocations to move freely.

As dislocation density increases, the resistance to dislocation movement increases. This is because the presence of more dislocations leads to more obstacles that other dislocations must overcome in order to move, which increases the strength of the material.

This question is incomplete, the complete question is;

A large tower is to be supported by a series of steel wires. It is estimated that the load on each wire will be 11,100 N.

Determine the minimum required wire radius assuming a factor of safety of 3 and a yield strength of 1500 MPa.

answer in mm please

Answer:

the minimum required wire radius is 5.3166 mm

Explanation:

Given that;

Load F = 11100N

N = 3

∝y = 1500 MPa

∝workmg = ∝y / N = 1500 / 3 = 500 MPa

now stress of Wire:

∝w = F/A

500 × 10⁶ = 11100 / A

A = 22.2 × 10⁻⁶ m²

so

(π/4)d² = A

(π/4)d² = 22.2 × 10⁻⁶

d² = 2.8265 × 10⁻⁵

d = 5.3165 7 × 10⁻³ m³

now we convert to mm(millimeters)

d = 5.3166 mm

Therefore the minimum required wire radius is 5.3166 mm

How helmet protects in a crash?

Helmets protect in a crash by absorbing the impact energy and reducing the risk of head injury. The foam inside a helmet deforms upon impact and spreads the force over a larger surface area, reducing the amount of energy that is transferred to the head and reducing the risk of injury.

Additionally, helmets also protect the face, jaw, and chin, reducing the risk of facial injuries in a crash.

Answer:

shrinkae limit = 20.35%

shrinkage ratio = 1.45

Explanation:

1. to get the shrinkage limit we would first calculate the moisture content w.

w = (37-28)/28

= 9/28

= 0.3214

then the formula for shrinkage limit is

\([w-\frac{(V-Vd}{wd} ]*100\)

w = 0.3214

V = 19.3

Vd = 16

Wd = 28

when we put these values into the formula:

\([0.3214-\frac{(19.3-16)}{28} ]*100\\\)

= 20.35%

2. the shrinkage limit = Wd/V

= 28/19.3

= 1.45

a The natural frequency of the paralysis transient response is 1.07 rad/s.

b The maximum possible percent paralysis if a 2% mixture of isoflurane is used is 7.63%.

c  The step response of paralysis if a 1% mixture of isoflurane is used

The percent isoflurane that would have to be used for 100% paralysis is 27.3%.

A. The damping ratio is given by ζ = −b/2√(a² - c²).

In this case, a = 1.15, b = 0, and c = 0.28,

The natural frequency of the paralysis transient response is given by ωn = √(a² - c²)

= √(1.15² - 0.28²)

= 1.07 rad/s.

B. The maximum possible percent paralysis is given by the steady-state value of the step response. In this case, the steady-state value is equal to the gain of the system, which is 7.63 × 10⁻².

Therefore, the maximum possible percent paralysis if a 2% mixture of isoflurane is used is 0.0763 = 7.63%.

C. The step response of paralysis if a 1% mixture of isoflurane is used is shown below.

Time (s) | Percent paralysis

------- | --------

0.0 | 0.00

0.1 | 0.03

0.2 | 0.06

0.3 | 0.09

0.4 | 0.12

0.5 | 0.15

0.6 | 0.18

0.7 | 0.21

0.8 | 0.24

0.9 | 0.27

1.0 | 0.30

As you can see, the percent paralysis increases rapidly at first, and then approaches a steady-state value of

= 7.63 × 10⁻²

= 7.63%.

D. For 100% paralysis, the percent paralysis must equal the gain of the system, which is 7.63 × 10⁻². Therefore, the percent isoflurane that would have to be used for 100% paralysis is

= 0.63 × 10⁻² / 0.28

= 27.3%.

Answer:

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

Explanation:

From Thermodynamics we remember that thermal efficiency of the ideal Otto cycle (\(\eta_{th}\)), dimensionless, is defined by the following formula:

\(\eta_{th} = 1-\frac{1}{r^{\gamma-1}}\) (Eq. 1)

Where:

\(r\) - Compression ratio, dimensionless.

\(\gamma\) - Specific heat ratio, dimensionless.

Please notice that specific heat ratio under cold air standard conditions is \(\gamma = 1.4\).

If we know that \(r = 8.2\) and \(\gamma = 1.4\), then thermal efficiency of the ideal Otto cycle is:

\(\eta_{th} = 1-\frac{1}{8.2^{1.4-1}}\)

\(\eta_{th} = 0.569\)

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

The field in Niger Delta, developed by NPDC has an estimated potential of 80,000,000 (80MM) barrels of oil. The development  is estimated to take about 4 years. The production is assumed to start at the end of the third year, and facilities will be constructed to handle 20,000 barrels of oil per day.

The economic limit is determined to be 600 barrels of oil per day. Determine a forecast of the annual production rate and cumulative production over the entire life of this field. Annual production rate: Annual production rate = 20,000 barrels of oil per day × 365 days Annual production rate = 7,300,000 barrels of oil per year.

At the end of the sixth year, the facility limit is expected to be reached, and the production will continue at a constant rate of 20,000 barrels of oil per day until the 12th year. Cumulative production: Production from year 0 to year 6 = 7,300,000 barrels of oil per year × 6 years.

Production from year 0 to year 6 = 43,800,000 barrels of oil Cumulative production from year 7 to year 12:Annual production rate = 20,000 barrels of oil per day × 365 days Annual production rate = 7,300,000 barrels of oil per year Cumulative production from year 7 to year 12 = 7,300,000 barrels of oil per year × 6 years Cumulative production from year 7 to year 12 = 43,800,000 barrels of oil.
