Explanation:

Cranking compression is simply the pressure that builds up inside cylinders when the valves are closed and the piston then moves up the bores to lead to compression of the mixture.

Cranking compression is normally measured in pounds per square inch (PSI).

When checking cranking compression, we should be looking for signs of replication between cylinders. It means that each cylinder should build pressure within about 5 percent of the others under the same number of starter revolutions. Thus, the variation between the highest and lowest readings should not be more than 10%

The question is incomplete.

Given the sample size and the standard deviation, a likely question could be to calculate the standard error (SE) of the mean

This is calculated as:

\(SE = \frac{\sigma}{\sqrt n}\)

Substitute values

\(SE = \frac{4.8}{\sqrt{100}}\)

Take the positive square root of 100

\(SE = \frac{4.8}{10}\)

\(SE = 0.48\)

Answer:

B) Minimum voltage drop across meter

Explanation:

An ammeter is a measuring instrument device that is used to measure small currents flowing through a circuit in milli-ampere. The internal resistance of the milli ammeter is very low so that there would be a minimum voltage drop across the meter causing a minimum effect of the current in the circuit, this results to a measurement closer to the original value. If a high resistance is place, there would be large voltage drop therefore the current measured would be lesser than the original value.

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

Springback in sheet-metal bending refers to the tendency of the metal to return to its original shape after being bent. This phenomenon occurs due to the elastic properties of the metal. In sheet-metal bending, the metal is subjected to plastic deformation, and this causes changes in the internal structure of the material. When the load is removed, the metal will tend to spring back to its original shape.

Option A is correct

https://brainly.com/question/29830237

#SPJ11

Springback is a common issue in sheet metal bending operations. It occurs when the metal tries to return to its original shape due to elastic recovery after being bent.

This can result in a deviation from the intended shape, which is undesirable. The elastic modulus, yield strength, overbending, and overstraining are all factors that affect the amount of springback, but the primary cause is the elastic recovery of the metal. This is because the metal undergoes plastic deformation during bending, which changes its shape permanently.

However, when the bending force is removed, the metal attempts to regain its original shape due to its elastic properties. To minimize springback, techniques such as overbending and bottoming can be used to account for the elastic recovery of the metal.

The behavior described, where a monkey quickly opens a box after observing another monkey do the same to access a banana, is an example of social learning or observational learning.

Observational learning is a process through which an individual acquires or modifies a behavior by observing the actions and outcomes of others. It involves the ability to learn by watching and imitating the behaviors of others, without requiring direct personal experience or trial-and-error learning.

In the given scenario, the first monkey observed the second monkey opening a box to access a banana. By witnessing this action and the positive outcome (obtaining the banana), the first monkey learned that the box can be opened to obtain a desired reward.

The quickness with which the first monkey opens a similar box suggests that it has learned through observation and is now applying that knowledge to achieve the same outcome. This behavior illustrates the ability to learn from others and imitate their actions, which is a characteristic of social learning.

Social learning is not limited to monkeys; it is a widespread phenomenon observed in many animal species, including humans. It plays a crucial role in the transmission of knowledge, acquisition of new skills, and the development of cultural traditions within a group or community.

(a) and (b) are false, while statement (c) and (d) are true. It is important to understand the key concepts and properties of linear programming and the simplex method to properly evaluate the given statements.

(a) False: In a particular iteration of the simplex method, if there is a tie for which variable should be the leaving basic variable, it does not necessarily mean that the next basic feasible (BF) solution must have at least one basic variable equal to zero. The leaving basic variable is chosen based on the minimum ratio test, which compares the ratios of the right-hand side values to the coefficients of the leaving variable in the entering column. The tie-breaking rule in case of a tie does not determine the value of the next BF solution.

(b) False: If there is no leaving basic variable at some iteration, it does not mean that the problem has no feasible solutions. It may indicate that the current solution is already optimal, and there is no variable with a positive coefficient in the objective function row that can improve the solution. This situation can occur when the problem is unbounded or when it has reached the optimal solution.

(c) False: If at least one of the basic variables has a coefficient of zero in row 0 of the final tableau, it does not imply that the problem has multiple optimal solutions. A coefficient of zero indicates that the corresponding variable does not contribute to the objective function's value. However, it does not necessarily mean that there are multiple ways to achieve the same optimal objective value. The presence of a zero coefficient does not directly indicate the existence of multiple optimal solutions.

(d) True: If the problem has multiple optimal solutions, then the problem must have a bounded feasible region. This is a fundamental property of linear programming. If a problem has multiple optimal solutions, it means that there are different combinations of decision variables that yield the same optimal objective value. For this to occur, the feasible region must be unbounded, allowing for different feasible solutions to exist. If the feasible region were not bounded, the problem would either be infeasible or have an infinite number of optimal solutions.

Answer:

the   isentropic efficiency of turbine is 99.65%

Explanation:

Given that:

Mass flow rate of LNG  m = 20 kg/s

The pressure at the inlet \(P_1 =30 \ bar\)  = 3000 kPa

turbine temperature at the inlet \(T_1 = -160^0C\) = ( -160+273)K = 113K

The pressure at the turbine exit \(P_2 = 3 bar\) = 300 kPa

Power produced by the turbine  W = 120 kW

Density of LNG \(\rho = 423.8 \ kg/m^3\)

The formula for the workdone by an ideal turbine can be expressed by:

\(W_{ideal} = \int\limits^2_1 {V} \, dP\)

\(W_{ideal} ={V} \int\limits^2_1 \, dP\)

\(W_{ideal} ={V} [P]^2_{1}\)

\(W_{ideal} ={V} [P_1-P_2]\)

We all know that density = mass * volume i.e \(\rho= m*V\)

Then ;

\(V = \dfrac{m}{\rho}\)

replacing it into the above previous derived formula; we have:

\(W_{ideal} ={ \dfrac{m}{\rho}} [P_1-P_2]\)

\(W_{ideal} ={ \dfrac{20}{423.8}} [3000-300]\)

\(W_{ideal} ={ \dfrac{20}{423.8}} [2700]\)

\(W_{ideal} =0.04719*[2700]\)

\(W_{ideal} =127.42 kW\)

However ; the isentropic efficiency of turbine is given by the relation:

\(n_{isen} =\dfrac{W}{W_{ideal}}\)

\(n_{isen} =\dfrac{120}{120.42}\)

\(n_{isen} =0.9965\)

\(n_{isen} =\) 99.65%

Therefore, the   isentropic efficiency of turbine is 99.65%

The transverse displacement will be 0.089963 m. The velocity of the shear wave particles is orthogonal to the direction of the wave.

What is transverse displacement?

Here given the data

Then the equation y(x,t)=Acos(kx−ωt)

speed (v) = 9.00 m/s

amplitude (A) = 9.00 × 10^−2 m

wavelength (λ )  = 0.480 m

We have to find out transverse displacement.

Here we know that.

v = angular frequency / wave number

also wave number = 2  / λ  

=  2  / 0.480  

= 13.0899

angular frequency = v x k

angular frequency = 9.00 × 13.0899

angular frequency = 117.8097 rad/sec

= 118 rad/sec

Therefore, the equation y(x,t)=Acos(kx−ωt)

y(x,t)=9.00 × 10^−2 cos(13.0899 x−118t)

If x =0 and and t = 0

Then, maximum y(x,t)= 9.00 × 10^−2 cos(13.0899 (0) − 118 (0))

= 9.00 × 10^−2  m

if x = 1.59 m and t = 0.150 s

Then,

y(x,t) = 9.00 × 10^−2 cos(13.0899 (1.59) −118(0.150) )

y(x,t) = 9.00 × 10^−2 × (0.99959)

y(x,t) = 0.089963 m
