0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).
Solving for how many kilograms of water must be added to increase the pressure to 70 Mpa (gage):To find the amount of water needed to increase the pressure to 70Mpa, we need to use the formula:
Change in volume = (Initial volume) x (Change in pressure)
Young's modulus
The initial volume of the container is 8 liters, since the container holds 8kg of water at standard pressure and the density of water is 1000 kg/m³.
So, change in volume = 8 x 10⁻³ m³
We know that the container expands by 1% when the pressure inside it is increased by 70 MPa, and we want to find the amount of water needed to increase the pressure to 70 MPa.
So, Change in pressure = 70 MPa
Young's modulus (K) = 2.05 GPa
Therefore, Change in volume = (8 x 10⁻³) x (70 / 2.05 x 10^9) = 2.68 x 10⁻⁵ m³
To find the amount of water needed to increase the pressure to 70 MPa, we need to multiply the change in volume by the density of water.
So, amount of water needed = (2.68 x 10⁻⁵) x (1000) = 0.268 kg
Therefore, 0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).

Consider a simple pendulum and compute the magnitude of the restoring force if the mass of the pendulum is 2 kg and the length of the pendulum is 0.5 m. Assume the pendulum is at the surface of the earth at sea level.
The magnitude of the restoring force if the mass of the pendulum is 2 kg and the length of the pendulum is 0.5 m. The answer is ∣Fres ∣=9.81 sin θ Nm.
How to find out the pendulum is at the surface of the earth at sea level.?We are given:
g = 9.8 m/s ^2 - acceleration due gravity
m = 2 kg - mass of body attached on the string
l = 0.5 m - length of pendulum
Required.
We are asked to find the magnitude of the restoring force under given conditions.
Step2:
First, we need to consider a given situation. In our case, we have a simple pendulum with a mass of the pendulum that is 2 kg, and a length of the pendulum is 0.5 m. Important to emphasize is that the observed pendulum is at the surface of the earth at sea level.
The restoring force for the pendulum has the units of the moment (generally restoring force need not have units of force) and depends on the angle that the pendulum closes with the vertical.
∣Fres ∣=m g l sin θ
Step3:
Finally, we need to substitute known values into equation (1) and solve it.

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.

FILL IN THE BLANK When a non-motor-operated electrical appliance lacks an overcurrent protective device rating, NEC 422.11(E) states that the branch circuit overcurrent protection shall be ____.
TRUE, additional overcurrent protection is utilized for equipment's internal circuits and parts, as well as for luminaires, appliances, and other types of equipment.
It shall be permitted to function as a substitute for needed branch-circuit overcurrent devices or in place of the required branch-circuit protection. When supplemental overcurrent protection is applied for internal circuits and equipment parts, it must not be used in place of the essential branch-circuit protection or as a replacement for needed branch-circuit overcurrent devices on luminaires, appliances, and other equipment. Additional overcurrent protection devices are not required. Each ungrounded conductor needs to have a series-connected fuse, overcurrent trip device, or circuit breaker. A current transformer and an overcurrent relay together make up an overcurrent trip device.

Machine learning (ml) and artificial intelligence are the fields where the problem of having too many skilled, business-savvy programmers is least likely to occur (ai).
Machine learning (ML), a subtype of artificial intelligence, is the method by which computers learn to recognize patterns or the capacity to continuously learn from and make predictions based on data, then make adjustments without being specifically programmed to do so. The way that machine learning works is quite complex and depends on the task at hand as well as the algorithm used to do it. But at its core, a machine learning model is a computer that scans data for patterns before applying what it learns to perform the task that has been handed to it more effectively. Even the more challenging tasks can be automated by machine learning if they depend on a set of data or rules.

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.

A furnace wall consists of 125 mm wide refractory brick and 125 mm wide insulating firebrick separated by an air gap. The outside wall is covered with a 12 mm thickness of plaster. The inner surface of the wall is at 11000C and the room temperature is 250C. The heat transfer coefficient from the outside wall surface to the air in the room is 17 W/m2K, and the resistant to heat flow of the air gap is 0. 16K/W. The thermal conductivities of refractory brick, insulating firebrick, and the plaster are 1. 6, 0. 3, and 0. 14 W/mK respectively. Calculate:
(i) the rate of heat loss per unit area of wall surface;
(ii) the temperature at each interface throughout the wall;
(iii) the temperature at the outside surface of the wall.
The temperature at the outside surface of the wall is 1344 0.8 watts.
What is the temperature at the outside surface of the wall?Determine the loss rate per square foot of the wall surface. Our refractor block brick's thermal resistance is equal to B divided by K. A times one. Thus, this is equal to 1.6 times one divided by 12.5 times 10 to the negative three. Our air gap contributes 0.16 K per W to our thermal resistance. We have three fire bricks as a result. Three divided by K gives us B. A thrice. This equals 0.3 times one divided by 1 25 times 10 to the negative three. Because of our plaster, four equals four divided by B divided by K.Four times our area is equal to 12 x 10 3 / 30.14 x 1 or 4 times our area. Furthermore, our thermal resistance is not equal to one divided by H but rather by A due to the heat transfer from the outside. This makes 1/7. The reason why adding R. One plus R. A plus R. three plus our four plus are ineffective is because of our total net thermal resistance. We thus obtain 0.799 K per W. The rate of heat loss throughout our entire surface area, Q, is equal to T. W minus T. Zero divided by R, or 111 100 minus 25 divided by 0.799, which is 1344 0.8 watts.To learn more about loss rate refer to:

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.
