Answer:

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.

Hi there!

For a particle to be in static equilibrium:

\(\huge\boxed{\Sigma \tau = 0}}\)

The sum of torques acting on the particle must equal 0 Nm.

\(\huge\boxed{\Sigma F = 0}}\)

The sum of forces acting on the particle must equal 0 N.

Both of these conditions MUST be met in order for a particle to be in STATIC equilibrium.

The number of hectares of each crop he should plant are; 250 hectares of Corn, 500 hectares of Wheat and 450 hectares of soybeans

He grows corn, wheat and soya beans on the farm of 1200 hectares. Thus;

C + W + S = 12   ----(1)

It costs $45 per hectare to grow corn, $60 to grow wheat, and $50 to grow soybeans. Thus;

45C + 60W + 50S = 63750  -----(2)

He will grow twice as many hectares of wheat as corn. Thus;

W = 2C    ------(3)

Put 2C for W in eq 1 and eq 2 to get;

C + 2C + S = 1200

3C + S = 1200     -----(4)

45C + 60(2C) + 50S = 63750

45C + 120C + 50S = 63750

165C + 50S = 63750    ------(5)

Solving eq 4 and 5 simultaneosly gives;

C = 250 and W = 500

Thus; S = 1200 - 3(250)

The capacitance-to-neutral in F/m is 8.742 × 10⁻¹²  F/m

The admittance-to-neutral in S/km is j3.296 × 10⁻⁶  S/km

The line charging current in kA/phase if the line is 110 km in length and is operated at 230 kV, I\(_{chg}\) = 4.814 × 10⁻¹²  kA/ Phase

A component or circuit's capacitance is its capacity to accumulate and store energy in the form of an electrical charge. The ratio of the electric charge on each conductor to the potential difference, or voltage, between them is used to express capacitance.

Farads (F), which bear the name of English physicist Michael Faraday, are the units used to measure the capacitance value of a capacitor (1791–1867).

A farad is a huge amount of capacitance. Most household electrical appliances contain capacitors that produce only a tiny amount of electricity, often a thousandth of a farad (or microfarad, or F), or as little as a picofarad (a trillionth, pF).

Answer:

The distance from rest to takeoff is 6116 meters, and the time from rest to takeoff is 138.9 seconds.

Explanation:

To calculate the distance and time from rest to takeoff for a jet transport with a constant acceleration of 0.4g, we can use the equations of motion for constant acceleration. The equations for distance and time are:

Distance: s = v0t + 0.5at^2

Time: t = (v - v0)/a

Where s is the distance, v0 is the initial velocity, t is the time, a is the acceleration, and v is the final velocity. In this case, we are given that the initial velocity is 0 (since the aircraft is at rest), the acceleration is 0.4g, and the final velocity is 200 km/h.

To convert the final velocity to meters per second, we need to first convert the velocity from kilometers per hour to meters per second. One kilometer is equal to 1000 meters, and one hour is equal to 3600 seconds, so 200 km/h is equal to 200 * 1000 / 3600 = 55.56 m/s.

We can then plug these values into the equations of motion to calculate the distance and time from rest to takeoff:

Distance: s = 0 * t + 0.5 * 0.4g * t^2

s = 0.2g * t^2

Time: t = (v - v0)/a

t = (55.56 - 0) / 0.4g

t = 138.9 seconds

Therefore, the distance from rest to takeoff is 0.2g * 138.9^2 = 6116 meters, and the time from rest to takeoff is 138.9 seconds.

Angled Physical Contact polish

So, To replace the fiber optic cable that connects two switches. If it is found that the existing fiber cable to ensure it has LC connectors and also if the cable's ferrule has a slight slant to it.

Angled Physical Contact polish should be used to replace the existing cable.

What is Angled Physical Contact polish?

APC Connector is a type of fiber connector that reduces back-reflection by applying a 5° to 15° angle-polish to the end faces.

Because of the angle, the reflected light escapes into the cladding rather than remaining in the fiber core.

Angled connectors should only be mated with other angled connectors. When mated to a non-angle polished connector, insertion loss is extremely high. Angle-polished connectors typically have a higher insertion loss than good quality straight physical contact connectors.

When connected, "Ultra" quality connectors may achieve back reflection comparable to an angled connector, but an angled connection maintains low back-reflection even when the output end of the fiber is disconnected.

SQL stands for Structured Query Language. It is a programming language used to manage and manipulate relational databases. SQL is used to communicate with a database, allowing users to create, read, update, and delete data from a database. SQL is widely used by software developers, database administrators, data analysts, and other professionals who work with data.

SQL consists of a set of commands that are used to interact with a database. These commands include SELECT, INSERT, UPDATE, DELETE, and others. SQL commands are used to retrieve data from a database, add new data, modify existing data, and delete data. SQL is used to create and manage database schemas, which define the structure of a database and the relationships between different tables.

The SQL statement SELECT 3 * 2 + 2 / 4 FROM DUAL; will produce a result of 6.5.

The statement is performing a simple arithmetic calculation, which involves multiplication, division, and addition. Here is the calculation part:

3 * 2 is calculated first, which gives us 6.

2 / 4 is calculated next, which gives us 0.5.

Finally, the results of step 1 and step 2 are added together, giving us the final result of 6.5.

Therefore, The keyword "FROM DUAL" is often used in Oracle databases to select a constant value. In this case, it doesn't have any impact on the calculation itself, as we're only performing a simple arithmetic operation.

For independent control of the engineer's mix and the musician's mix, headphone sends should be split. Headphone sends should be split if there is a need for independent control of the engineer's mix and the musician's mix.

When the headphone sends are split, it means that different audio signals are being sent to each musician. As a result, each musician has control over their mix, and the engineer has control over the final mix.

The headphone sends can be split in a variety of ways. There are dedicated headphone mixers available on the market, which can provide separate mixes to each musician. Alternatively, individual mixer sends can be used to create separate headphone mixes.

This can be achieved by assigning each musician a mixer send, which is then used to send a unique mix to each musician's headphones.

The power exerted by the dominant group over minority groups through institutions, such as mass media and popular culture, in order to communicate and reinforce ruling values and beliefs that may be adopted by members of the minority group is referred to as hegemony.

The term "hegemony" best describes the concept described in the question. Hegemony refers to the social, cultural, and ideological influence wielded by the dominant group over subordinate groups within a society. It involves the imposition of dominant norms, values, and beliefs that shape the worldview and behavior of both the dominant and subordinate groups.

In this context, institutions like mass media and popular culture play a significant role in disseminating and reinforcing the ideologies and narratives of the dominant group. By controlling the representation, portrayal, and dissemination of information, the dominant group can shape public opinion and maintain their position of power and control.

However, it is important to note that while hegemony influences the beliefs and behaviors of some members of the minority group, it does not encompass all forms of discrimination, racism, or oppression. These terms represent specific manifestations of power imbalances and discriminatory practices, which can be reinforced by hegemonic systems but are not limited to them.

Bending moment M = 1500 lb - ft

axial thrust P = 2500 lb

yield points for tension  σY= 100 ksi

yield points for shear   τY = 50 ksi

Using maximum-shear-stress theory

\(\sigma_A = \dfrac{P}{A}+\dfrac{Mc}{I}\)

where;

\(A = \pi c^2\)

\(I = \dfrac{\pi}{4}c^4\)

\(\sigma_A = \dfrac{P}{\pi c^2}+\dfrac{Mc}{ \dfrac{\pi}{4}c^4}\)

\(\sigma_A = \dfrac{2500}{\pi c^2}+\dfrac{1500*12c}{ \dfrac{\pi}{4}c^4}\)

\(\tau_A = \dfrac{T_c}{\tau}\)

where;

\(\tau = \dfrac{\pi c^4}{2}\)
