The  feature of a thread is checked with a thread micrometer  are:

Major diameter

Pitch diameter

Minor diameter

What is the thread?

A thread micrometer is a specialized measuring instrument used to measure the major diameter, minor diameter, and pitch diameter of external threads. The major diameter is the largest diameter of the thread, while the minor diameter is the smallest diameter of the thread. The pitch diameter is the diameter at which the width of the thread and the width of the space between the threads are equal.

The crest radius and root radius of a thread are not typically checked with a thread micrometer. These measurements are instead checked using specialized measuring instruments known as thread profile gauges, which are designed to measure the shape and size of the thread's crest and root.

Answers

High frequency is a high voltage, low current, and high hertz arc to start and stabilize the welding arc, hence option A is correct.

What is a high frequency arc welding?

The process of connecting materials using a high frequency (HF) electromagnetic field (27.12 MHz) and pressure is known as high frequency (HF) or radio frequency (RF) welding.

The user can place the tungsten electrode close to the task at hand and spark the arc by just depressing the torch trigger. Professional TIG welding equipment with AC/DC functionality.

The high frequency function is disabled once your arc has begun until you are ready to restart it. With lift start, there is no arc jump between the tip of the tungsten and the metal. You still utilize your trigger or foot pedal.

A culture of bacteria has an initial population of 94000 bacteria and doubles every 10 hours. Using the formula P t ​ =P 0 ​ ⋅2 d t ​ , where P t ​ is the population after t hours, P 0 ​ is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 13 hours, to the nearest whole number?

Answers

The population is modeled by the exponential equation:

P(x) = 94,000*(2)^(x/10)

And the population after 13 hours is 231,455 bacteria.

What is the population after 13 hours?

The population can be modeled with an exponential equation of the form:

P(x) = A*(b)^x

Where A is the initial population, b defines the rate of growth/decay, and x represents the time.

Here the initial population is 94,000 bacteria, and it doubles every 10 hours, then we can write the exponential equation as:

P(x) = 94,000*(2)^(x/10)

Notice that there is a 1/10 factor in the exponent because the doubling thing happens every 10 hours, then the population after 13 hours is:

P(13) =94,000*(2)^(13/10) = 231,455 bacteria.
