Micropulse arc welding is a well-known tool for speeding up simple bench operations during the welding process like ring size, making connections near thermally sensitive gemstones, and mending porosity castings.

The practice performs effectively on gold, silver, copper, and stainless steel whether joining tiny jewelry materials or bigger pieces for miniature metal sculptures.

The welding arc temperatures typically range from 6000°C to 8000°C, which translates to about 10000F to 15000F.

This increased range of thermal heat is high enough to turn Gold and silver rings into a molten state. A molten state is a phase at which a solid element is being melted and turns into a liquid state under the influence of a high temperature.

Answer:

i think its called leggings thats wut my shop teacher told me

Explanation:

Both a voltmeter and an ammeter must be inserted directly into the current path to make a measurement. To measure voltage (potential difference) in a circuit, a voltmeter must be connected in parallel across the component or section of the circuit where the voltage is to be measured.

This allows the voltmeter to measure the potential difference between two points in the circuit. To measure current flowing through a circuit, an ammeter must be connected in series with the component or section of the circuit where the current is to be measured. By connecting the ammeter in series, the current passes through the ammeter, allowing it to measure the magnitude of the current.

On the other hand, an ohmmeter is used to measure resistance in a circuit. It does not need to be inserted directly into the current path. Instead, it measures resistance by applying a known voltage to the circuit and measuring the resulting current flow. Therefore, an ohmmeter does not need to be inserted directly into the current path to make a measurement.

Most technicians install rebuilt or new power steering pumps rather than overhauling the defective unit in the shop.

True

Explanation:

It has been established that most technicians, instead of overhauling the defective power steering pumps, prefer to install rebuilt or revamped pumps or even new pumps when they could have overhauled the unit themselves.  Some are afraid that leakage could occur again.  They are not confident enough to do the overhauling in-house or some claim that they do not have the time and other tools to carry out the overhauling.  Acknowledgedly, overhauling a power steering pump is not a job for the novice.  They require experienced and skilled hands to do the hard work.

Using the Newton's second law of motion we will see that the acceleration is  0.0875 m/s^2.

The acceleration of a vehicle is determined by the force acting on it and its mass, as described by Newton's second law of motion:

F = m * a

where F is the force acting on the object, m is the mass of the object, and a is the resulting acceleration.

In this case, the force acting on the vehicle is 0.07 N, and the mass of the vehicle is 0.8 kg. Substituting these values into the equation above, we get:

0.07 N = 0.8 kg * a

Solving for a, we get:

a = 0.07 N / 0.8 kg

a = 0.0875 m/s^2

According to the information we can infer that the displacement of the airplane is 86 km due North (a); On the other hand, the pilot would take 10 minutes for the same flight if the average velocity of the airplane is increased by 20% (b).

To calculate the displacement of the airplane, we can use the formula:

Given that the velocity of the airplane is 430 km/h and it flies for 12 minutes, we can convert the time to hours by dividing it by 60:

Now we can calculate the displacement:

So, the displacement of the airplane is 86 km due North.

If the average velocity of the airplane is increased by 20%, we need to find the new velocity. 20% increase in velocity means adding 20% of the current velocity to the current velocity:

Now, we can calculate the time it would take for the same flight with the new velocity. Using the formula:

Time = 86 km / 516 km/h = 0.167 hours

Answer:

The answer is VN =37.416 m/s

Explanation:

Recall that:

Pressure (atmospheric) = 100 kPa

So. we solve for the maximum velocity (m/s) to which water can be accelerated by the nozzles

Now,

Pabs =Patm + Pgauge = 800 KN/m²

Thus

PT/9.81 + VT²/2g =PN/9.81  + VN²/2g

Here

Acceleration due to gravity = 9.81 m/s

800/9.81 + 0

= 100/9.81 + VN²/19.62

Here,

9.81 * 2= 19.62

Thus,

VN²/19.62 = 700/9.81

So,

VN² =1400

VN =37.416 m/s

Note: (800 - 100) = 700

Answer:

\(V2 = 37.417ms^{-1}\)

Explanation:

Given the following data;

Water enters the turbine nozzles (inlet) = 800kPa = 800000pa.

Nozzle outlets = 100kPa = 100000pa.

Density of water = 1000kg/m³.

We would apply, the Bernoulli equation between the inlet and outlet;

\(\frac{P_{1} }{d}+\frac{V1^{2} }{2} +gz_{1} = \frac{P_{2} }{d}+\frac{V2^{2} }{2} +gz_{2}\)

Where, V1 is approximately equal to zero(0).

Z\(z_{1} = z_{2}\)

Therefore, to find the maximum velocity, V2;

\(V2 = \sqrt{2(\frac{P_{1} }{d}-\frac{P_{2} }{d}) }\)

\(V2 = \sqrt{2(\frac{800000}{1000}-\frac{100000}{1000}) }\)

\(V2 = \sqrt{2(800-100)}\)

\(V2 = \sqrt{2(700)}\)

\(V2 = \sqrt{1400}\)

\(V2 = 37.417ms^{-1}\)

Hence, the maximum velocity, V2 is 37.417m/s

Explanation:

The situation being described completely fails in regard to the importance of metrology. This is because the main importance of metrology is making sure that all of the measurements in a process are as accurate as possible. This accuracy allows an entire process to function efficiently and without errors. In a food production plant, each individual department of the plant relies on the previous function to have completed their job with the correct and accurate instructions so that they can fulfill their functions correctly and end up with a perfect product. If the oven (like in this scenario) is a couple of degrees off it can cause the product to come out burned or undercooked, which will then get transferred to the next part of production which will also fail due to the failed input (burned or undercooked product). This will ultimately lead to an unusable product at the end of the process and money wasted. Which in a large production plant means thousands of products in a single batch are thrown away.

In terms of the necessity of metrology, the situation stated absolutely fails. This is because metrology's primary goal is to ensure that all measurements in a process are as precise as feasible. This precision allows a whole process to run smoothly and error-free. If the oven temperature is wrong by a few degrees, the product will come out charred or undercooked, and the product will be sent to the next step of the process, which will also fail owing to the failed input. This will result in a useless product and a waste of money at the end of the procedure. In a big manufacturing facility, this means thousands of goods are discarded in a single batch.
