When a disc rotates at high speeds in the air, there are aerodynamic effects that are created by the air that flows between the disc and the reader head.

To estimate the shearing force on the reader head as a result of the air between the disc and the head, we need to use the Bernoulli equation and some basic assumptions. We will assume that the flow of air is incompressible, laminar, and steady-state. We will also assume that the reader head is a flat plate that is parallel to the surface of the disc.

Therefore, the estimated shearing force on the reader head as a result of the air between the disc and the head is 3,372,692.1 N.

Answer:

(0, 0.04)

Explanation: Given that At time t = 0, a particle is at rest in the x‐y plane at the coordinates (x0, y0) = (6, 0) in. If the particle is then subjected to the acceleration components ax = 0.5 − 0.35t in./sec^2 and ay = 0.15t − 0.02t^2 in./sec^2.

differentiate ax and ay twice. That is, second derivatives to get the position

dax/dt =  − 0.35

d^2ax/dt^2 = 0

and

day/dt = 0.15 − 0.04t

d^2ay/dt^2 = 0.04

the coordinate of the particle after t = 6 sec will be (0, 0.04)

the graph will be linear

Answer:

\(W=46141.72~J\)

Explanation:

Given:

initial pressure, \(P_1=14~bar=1.4\times10^6~Pa\)

initial volume, \(V_1=0.03~m^3\)

After isothermal expansion:

final volume, \(V_2=3V_1=0.09~m^3\)

a)

We have the work done in isothermal process as:

\(W=P_1.V_1\ln(\frac{V_2}{V_1} )\)

\(W=1.4\times10^6\times 0.03\ln(\frac{0.09}{0.03} )\)

\(W=46141.72~J\) is the work by the gas in moving the external force

b)

When the force on piston is suddenly reduced to half the initial value then the process becomes near to adiabatic.

\(P_1V_1^{\gamma}=P_2V_2^{\gamma}\)

\(14\times 0.03^{1.4}=P_2\times 0.09^{1.4}\)

\(P_2=3~bar\)

Now, using the formula for work done in adiabatic process:

\(W=\frac{P_1V_1-P_2V_2}{\gamma-1}\)

\(W=\frac{1.4\times10^6\times 0.03-3\times10^5\times 0.09}{1.4-1}\)

\(W=3750~J\)

Answer:

The voltage gain is 2.07.

Explanation:

Given that,

Resistance \(R_{1}=14\ k\Omega\)

Resistance \(R_{2}=13\ k\Omega\)

We need to calculate the voltage gain

Using formula of voltage source

\(V_{s}=\dfrac{V_{o}\times R_{2}}{R_{1}+R_{2}}\)

\(\dfrac{V_{o}}{V_{s}}=\dfrac{R_{1}+R_{2}}{R_{2}}\)

Where, \(R_{1}\) = first resistance

\(R_{2}\) =second resistance

\(V_{s}\) = source voltage

\(V_{o}\) = output voltage

Put the value into the formula

\(\dfrac{V_{o}}{V_{s}}=\dfrac{14+13}{13}\)

\(\dfrac{V_{o}}{V_{s}}=2.07\)

Hence, The voltage gain is 2.07

It's the law. Under New York law, you can get a citation for riding your bike while listening to music using headphones or earbuds in both ears. It is lawful, however, to listen to music with only one earbud keeping the other ear free.

Sensory deprivation. One of the main ways that people alert each other to danger on the road is through sound. Whether it's honking, yelling or ringing a bicycle bell, you're less likely to hear any of these warnings if you're listening to music putting you at higher risk of an accident.

Decreased attention. The more stimuli you have to contend with, the more difficult it is to dedicate your full attention to one particular task. If you get caught up in a song or story you're listening to while cycling, it can increase your distractibility which could have disastrous consequences.

The majority of cycling-related accidents involve a cyclist and a motor vehicle. Not surprisingly, the injuries a cyclist suffers in such collisions tend to be disproportionately serious and often fatal. Therefore, if you're cycling in traffic, foregoing the headphones can prove to be a life-saving decision.

The correct statements about a default VPC are "B: AWS creates a default VPC in each region and D: By default, each default VPC is available to one AWS account".

A default VPC is a pre-configured VPC provided by AWS when you create an AWS account. It is ready to use and simplifies the process of launching instances.

The first statement is true because AWS creates a default VPC in each region. This means that when you create a new AWS account, a default VPC is automatically created for you in each region where AWS provides services.

The second statement is also true as the default VPC is available by default to the AWS account that it was created with. This means that resources within the default VPC, such as instances and subnets, can be accessed and used by the AWS account without any additional configuration.

Therefore, Option B and Option D are the correct answers.

Answer:

Resistance of copper = 1.54 * 10^18 Ohms

Explanation:

Given the following data;

Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m

Resistivity, P = 1.7 * 10^8 Ωm

Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m

\( Radius, r = \frac {diameter}{2} \)

\( Radius = \frac {0.00065}{2} \)

Radius = 0.000325 m

To find the resistance;

Mathematically, resistance is given by the formula;

\( Resistance = P \frac {L}{A} \)

Where;

First of all, we would find the cross-sectional area of copper.

Area of circle = πr²

Substituting into the equation, we have;

Area  = 3.142 * (0.000325)²

Area = 3.142 * 1.05625 × 10^-7

Area = 3.32 × 10^-7 m²

Now, to find the resistance of copper;

\( Resistance = 1.7 * 10^{8} \frac {3000}{3.32 * 10^{-7}} \)

\( Resistance = 1.7 * 10^{8} * 903614.46 \)

Resistance = 1.54 * 10^18 Ohms

The indirect tire-pressure monitoring system is being discussed between two technicians. A technician claims that certain automakers have employed it.

According to technician B, in order to identify a low tyre, the rotating speeds of the rf and lr tyres are compared. The fact that BOTH technicians are accurate should not be overlooked. Indirect tyre pressure monitoring systems are those that do not use air pressure sensors inside the tyres (TPMS). Instead, they analyse relative wheel revolutions using the ABS wheel speed sensors to detect a low tyre. If the driver calibrates the system while any tyre is underinflated, the system will not report properly. The driver can calibrate the system by pressing a reset button on the dashboard or through the electronic controller.

To check if a variable name is accepted by the programming language, we need to split the variable name into its constituent words and check if each word is present in the list of valid words. We can do this by iterating through the variable name string and keeping track of the start and end indices of each word.

If a word is found that is not in the list of valid words, the function should return false. If all the words are valid, the function should return true. Here's a sample implementation in C++: ``` bool camelCaseSeparation(vector words, string variableName) { int n = variableName.length(); int start = 0; vector parts; // split the variable name into constituent words for (int i = 1; i < n; i++) { if (isupper(variableName[i])) { parts.push_back(variableName.substr(start, i - start));  start = i; } } parts.push_back(variableName.substr(start)); // check if all the words are in the list of valid words for (string part : parts) { bool found = false; for (string word : words) { if (part == word) { found = true; break; } } if (!found) { return false;  } } return true; } ``` The function takes in the list of valid words as a vector of strings and the variable name as a string. It then iterates through the variable name to split it into constituent words, using the `isupper` function to detect the start of each word. It then checks if each word is present in the list of valid words, and returns false if any of them are not found. If all the words are valid, the function returns true.

A caisson is a watertight enclosure that can be pumped dry so that construction activities, such as the construction of piers can take place. A caisson is a watertight structure or chamber, usually made of wood, metal, or concrete, that is sunk to the bed of a river, lake, or ocean to provide a foundation or support for a bridge, building, or other structure.

A caisson is constructed onshore and then floated to the location where it is to be sunk into the water. Once in place, water is pumped out of the caisson, and construction workers enter the dry chamber to begin work on the foundation or support structure. The use of caissons has been an important development in the construction of bridges and other structures in areas with deep water or unstable soils.

A foundation called a caisson is used in construction on soft or deep water. It involves filling a series of large, watertight cylinders with concrete and sinking them into the ground. The base serves as a solid foundation for any subsequent structures. The construction of large structures like bridges, docks, and caissons is common.
