If you are working on the part of 5-15 minutes, time-stamping (every 30 seconds) should start at.

Answers

TIMESTAMPS

A timestamp is an indication (also called a marker) which tells us at what time / when the relevant text was spoken. They are represented in the format [HH:MM:SS]; where HH are hours, MM are minutes, and SS are seconds - from the beginning of the audio or video file.

There are different kinds of timestamps as below:

1. Periodic timestamps - Periodic timestamps appear at a consistent frequency. They can appear for every 15 seconds, 30 seconds, 1 minute, or 2 minutes.

2. Paragraph timestamps

3. Sentence timestamps

4. Speaker timestamps

Time stamping format used while transcribing audio files is:

[00:00:00]    

where [hour:minute:second]

so 5th minute is [00:05:00]

If the 5 - 15 minute part of an audio has to be transcribed stamping should be started at [00:05:00]

If a client requests time stamping every 30 seconds the next timestamp would be [00:05:30]

in the late 1800s, china experienced an internal crisis when emperor guang xu launched massive reforms throughout the nation. why were these reforms opposed, thus creating an internal crisis in china?

Answers

Note that in the late 1800s, China experienced an internal crisis when emperor Guang Xu launched massive reforms throughout the nation. It is to be noted that these reforms were opposed and hence caused internal crises because: "Some people felt reforms would ruin the Chinese economy." (Option A)

How did the crises erupt?

Among many persons, Prince Duan, a late Qing dynasty stateman, was the most vocal in his opposition to the changes. Prince Duan had resisted the changes because he felt a foreign scheme was at work, with many Western concepts, including military tactics, education, and political methods, being proposed for implementation, and he was threatening to deport all foreigners from China.

As a result, they executed and imprisoned all reform supporters and held King Guang Xu under house arrest until his death.

According to some historians, Emperor Guang Xu was the first Chinese ruler to pursue modernizing reforms and capitalism. Imperial power in the Qing dynasty reached a low under Guangxu, and he was the first Qing emperor to be imprisoned during his own reign.

The way you should feel after your first meeting with a lawyer who says "i will win this case. In fact, i’ve never lost a case like this." is;

C: Wary

Usually, it's not all cases that lawyers win and even when you meet a lawyer to defend your case, lawyers don't just say straight from the get go that they will win the case and that they have never lost a case like that because there are a lot of things that go into court cases.

Therefore, what the lawyer could have done is to just assure you that he is willing to work to the best of his ability to defend your case and that hopefully the court judges will rule in your favor because the lawyer himself is not the judge.

In conclusion, you should be wary of the lawyer.

Answer:

Answer is C-B and E-D

Explanation:

B - C and E - D are the segments show changes of state that release heat. Hence option 2 and 4 is correct.

What are segments?

Segments are defined as a part of a company that produces its own products, product lines, or service offers and makes its own profits. A segment is a specific length portion of a line with two endpoints. On the other hand, a ray is also a component of a line that has one terminus and an infinitely long other direction.

The material is converting from a solid to a liquid in segments B and C.  Since the heat is being used to separate the particles from the solid and transport them into the liquid phase, there is no change in temperature. The material is transitioning from a liquid to a gas in segments D to E. . Because the heat is being used to separate the particles from the liquid and transport them into the gas phase, there is no change in temperature.

Thus, B - C and E - D are the segments show changes of state that release heat. Hence option 2 and 4 is correct.
