1. A steel container expands in volume 1% when the pressure with in it is increased by 70Mpa. At standard pressure, it holds 8kg of water; =1000kg/m3. For K=2.05Gpa, when it is filled, how many kilograms of water must be added to increase the pressure to 70Mpa (gage)?
Using the ideal gas law to solve the question,
We need to add 0.331 kg of water to increase the pressure to 70 MPa.
How The ideal gas law was appliedWe can use the Ideal Gas Law to solve this problem.
The Ideal Gas Law states that PV = nRT,
where P is the pressure,
V is the volume,
n is the number of moles,
R is the gas constant,
T is the temperature (assumed to be constant).
We know that the container expands by 1% when the pressure is increased by 70 Mpa, so the change in volume is (1/100)V.
We can use this to find the initial volume of the container:
V = (1/0.01) * (1/100)V = 100V
We also know that at standard pressure, the container holds 8 kg of water, which we can assume is 8 liters. So the volume of the container at standard pressure is 8 L.
We can use the bulk modulus of elasticity of steel, K = 2.05 Gpa, to find the change in pressure.
K = (Delta P) / (Delta V/V)
Delta P = K * (Delta V/V)
Delta P = (2.05 * 10^9 Pa) * (1/100) = 2.05 * 10^7 Pa
This is the same as 20.5 MPa. So we need to add 49.5 MPa (70 - 20.5 = 49.5) more pressure to fill the container to 70 MPa.
Now we can use the Ideal Gas Law to find the number of moles of water we need to add to increase the pressure by 49.5 MPa.
PV = nRT
n = (PV) / (RT)
n = (49.5 * 10^6 Pa * 8 L) / (8.314 J/mol·K * 300 K)
n = 0.0186 moles
To find the mass of water we need to add, we can use the molar mass of water, which is 18.02 g/mol:
mass = n * molar mass
mass = 0.0186 moles * 18.02 g/mol
mass = 0.331 kg
So we need to add 0.331 kg of water to increase the pressure to 70 MPa.

At trial, the insurer called as an expert witness an engineer, who testified that the pipe had burst because of age rather than freezing.
On cross-examination, the engineer admitted that five years earlier, he had been convicted of tax fraud, even though he had asserted that it was his accountant's error. In response, the insurer calls a witness, who is well acquainted with the engineer and his reputation, to testify that (1) in the witness's opinion, the engineer is a truthful person, and (2) the engineer's neighbors all describe him as a truthful person.
How much, if any, of the witness's testimony is admissible?
Under the Federal Rules of Evidence, the witness's testimony is only partially admissible.
How much, if any, of the witness's testimony is admissible?The witness's opinion of the engineer's truthfulness is admissible, as it is an expression of opinion (Rule 701) and not based solely on the witness's specialized knowledge (Rule 702). However, the testimony about what the engineer's neighbors say about him is inadmissible hearsay (Rule 801) and therefore should be excluded.The witness's testimony regarding the engineer's reputation for truthfulness is likely to be admissible. Generally, testimony regarding a witness's reputation for truthfulness or untruthfulness is admissible in some form. In this case, the witness's opinion as to the engineer's truthfulness is likely to be admissible, but his testimony regarding the engineer's neighbors' opinions may not be admissible.This is because the neighbors' opinions are hearsay and therefore not reliable.

how to make demultiplexer using or gates?
Answer:
A demultiplexer (DEMUX) is a digital circuit that routes a single input line to one of several output lines. It can be implemented using OR gates.
Here's one way to make a 2-to-4 demultiplexer using OR gates:
Begin by connecting the input line to the input of the first OR gate.
Connect one of the select lines to the second input of the first OR gate.
Connect the output of the first OR gate to one of the outputs.
Connect the second select line to the second input of the second OR gate.
Connect the output of the first OR gate to one input of the second OR gate.
Connect the output of the second OR gate to the second output.
Repeat steps 4-6 for the remaining outputs.
By this way you can construct a demultiplexer using OR gates.
It's important to note that the number of select lines must be equal to the number of bits required to select the output. In this example, we used 2 select lines to control the 4 outputs, so we only needed 2 bits to select the output.
Learn how changes in binding free energy affect binding and the ratio of unbound and bound molecules. Similar to the lecture, our example is a drug molecule D and a drug target enzyme E. The drug target enzyme E is commonly found in concentrations [E]tot of 250 nM, i.e. 2.5 x 10-7 mol/l. The drug D binds to E to form the complex ED with a dissociation constant of KD = 1.30 µM (i.e. 1.30 x 10-6). The dissociation constant has been determined at room temperature, i.e. for T = 298.15 K.
In order to estimate the effectivity of the drug D, calculate the ratio of the concentration of the free, unbound drug molecules [D] and the bound complex [ED], i.e. [D]/[ED], for the conditions described in part B. Provide your answer with 3 significant figures.
The margin of error is 2%.
The binding free energy for the formation of the complex ED is -2.94 kJ/mol.
The binding free energy for the formation of the complex ED can be calculated using the equation ΔG = -RTlnKD. Using the given values of R (8.314 J/mol·K), T (298.15 K), and KD (1.30 x 10-6), we get:
ΔG = -(8.314 J/mol·K)(298.15 K)ln(1.30 x 10-6) = -2.94 kJ/mol
2.) To find the dissociation constant for the complex ED', we use the equation ΔG = -RTlnKD. The binding free energy for ED' is 10.5 kJ/mol more negative than for ED, so we can substitute in the new value for ΔG:
ΔG' = -2.94 kJ/mol - 10.5 kJ/mol = -13.44 kJ/mol
Solving for KD':
KD' = e^(-ΔG'/RT) = e^(-(-13.44 kJ/mol)/(8.314 J/mol·K)(298.15 K)) = 2.09 x 10^-7 mol/l
3.) To find the total concentration of the drug D' that is needed to bind 50% of the enzyme E, we use the equation:

technician a says all differentials are vented. technician b says that a clogged vent can cause the rear axle seal to leak. which technician
Technician B is correct. Differentials are typically vented to allow air to escape and prevent pressure from building up inside the differential.
If the vent becomes clogged, the pressure inside the differential can build up and cause the rear axle seal to leak. This can lead to oil leaking from the differential, which can cause damage to the differential and other components. It is important to check the vent regularly to ensure that it is not clogged and that the differential is operating properly. Differentials are a type of gearbox used in vehicles to transfer power from the engine to the wheels. They are typically made up of two or more gears that are connected to each other and to the drive shaft. Differentials are used to allow the wheels to rotate at different speeds, which is necessary when turning a corner. Differentials are also used to provide power to the wheels when accelerating or decelerating. Differentials are typically vented to allow air to escape and prevent pressure from building up inside the differential and are also used in other applications, such as in robotics and industrial machinery.

The time response of the coil current after the switch S is closed, as a function of theprecharge voltage Vx. (Some types of stimulation require a field with a fast rise time anda slow fall time.)2. The peak coil current for Vx = 950 V.3. The time t1 at which diode D turns on.4. The energy dissipated in the resistor for Vx = 950 V
The theory used in this question is based on the analysis of RC circuits. Energy dissipated in the resistor for Vx = 950 V
E = 950^2/(2*R*C).
Analysis of RC circuits
This type of analysis is used to determine the time response of a circuit, as well as the current and energy dissipated in different components. Specifically, this question uses the equation for the current in an RC circuit (I = CdV/dt) and the equation for the power dissipated in a resistor (P = I^2 * R) to calculate the time response, peak current, and energy dissipated in the resistor for a given precharge voltage.
1. The time response of the coil current after the switch S is closed, as a function of the precharge voltage Vx, can be determined by analyzing the RC circuit.
The current in the coil is given by: I = CdV/dt, where C is the capacitance and V is the voltage across the capacitor.
At t = 0, the capacitor is precharged to Vx, and the current will rise exponentially until the diode turns on, at which point the current will plateau.
Therefore, the time response of the coil current is given by:
I(t) = I0 * e^(-t/RC),
where I0 is the initial current determined by Vx, R is the resistance of the resistor, and C is the capacitance of the capacitor.
2. The peak coil current for Vx = 950 V can be determined using the equation above.
Since the capacitor is precharged to 950 V, the initial current is given by:
I0 = 950/(R*C).
Substituting this value into the equation for I(t) and solving for t = 0 gives the peak coil current:
Ipeak = 950/(R*C).
3. The time t1 at which diode D turns on can be determined by examining the equation for I(t).
The diode will turn on when the current reaches the peak value, which occurs when t = 0.
Therefore, t1 = 0.
4. The energy dissipated in the resistor for Vx = 950 V can be determined by integrating the power dissipated in the resistor over time. The power dissipated in the resistor is given by:
P = I^2 * R.
Therefore, the energy dissipated in the resistor is given by:
E = integral from 0 to infinity of I^2 * R dt.
Substituting the equation for I(t) into this equation and solving for t = 0 gives the energy dissipated in the resistor for Vx = 950 V:
E = 950^2/(2*R*C).

The board is made from southern yellow pine, which has an air dry weight density of. 025 lb/in. 3. A. What is the volume of the wood board? Precision = 0. 0
This question uses the theory of volume, which states that the volume of an object is the product of its width, depth, and height. The volume of the wood board is 221.25 cubic inches.
What is the volume of an object?
Volume is a measure of the amount of three-dimensional space a substance or object occupies. It is the amount of space that an object or substance occupies, or that is enclosed within a container. It is usually expressed in cubic units, such as liters (L), cubic centimeters (cm3), or cubic meters (m3). The basic formula for calculating the volume of a three-dimensional shape is length x width x height. This formula can be used to calculate the volume of a cube, rectangular prism, cylinder, or other three-dimensional shape.
The steps for the answer as follows:
Step 1: Calculate the volume of the board. This is done by multiplying the width, depth and height of the board together.
Step 2: The width, depth, and height of the board are 7.5, 14, and 1.75 inches, respectively.

The number of times the second string appears in the first string is returned by a method that takes two String inputs.
In computer programming, a string is often a collection of characters, either as a literal constant or as a kind of variable. Both the former and the latter have movable parts and lengths (after creation). A string is often implemented as a character-encoded array of bytes (or words) that stores a succession of components, usually characters. Typically, a string is considered to be a type of data. Another sequence (or list) data types and structures, such as more general arrays, can also be represented by a string. When a variable is defined to be a string, memory space may be statically allocated for only as long as that variable can be, or it may employ dynamic allocation.

A variable is a named storage location in a computer program that holds a value that can be changed during the execution of the program. Variables are used to store data and information that can be used throughout the program. Variables can be declared and assigned values in a variety of ways, depending on the programming language being used. Variables can be of different types, such as integers, strings, floats, and booleans. Each type of variable has a different set of characteristics and can be used for different purposes. For example, an integer variable can store a whole number, while a string variable can store a sequence of characters. Variables can also be declared as constants, which means that their value cannot be changed during the execution of the program.

questiona test car and its driver, with a combined mass of 600 kg, are moving along a straight, horizontal track when a malfunction causes the tires to stop rotating. the car skids to a halt with constant acceleration, leaving skid marks on the road during the whole time it skids. which two of the following measurements, taken together, would allow engineers to find the total mechanical energy dissipated during the skid? select two answers.
The two measurements that, taken together, would allow engineers to find the total mechanical energy dissipated during the skid are:
A. The length of the skid marks
C. The coefficient of static friction between the tires and the track.
The length of the skid marks can be used to determine the distance over which the car decelerated and came to a stop.
This distance, combined with the car's mass, can be used to calculate the work done by the friction force (which is equal to the mechanical energy dissipated) using the equation:
Work = force x distance
The coefficient of static friction between the tires and the track is necessary to calculate the friction force.
The friction force can be determined using the equation:
Friction force = coefficient of static friction x normal force
The normal force can be calculated from the car's mass and the acceleration due to gravity.
By combining the length of the skid marks (distance) with the coefficient of static friction, engineers can determine the total mechanical energy dissipated during the skid.
Hence, option A and option C are correct.
