Old error of Ethereum Level 2 password

1. First click to titanium workshop, then click I want to sell, then look for the things you want to sell, then input your own secondary password, and then click confirm to sell

2. As long as you reset the level 2 password, it will not go off in seven days. Just set another one.

3. Although it's a little short to come to Macao for a day, you can also see many scenic spots. In the morning, you can go to dashanba and Mazu temple to have a look. On the Macao Peninsula, these are the places you must visit when you come to Macao. In the afternoon, you can go to guanye street to taste some of Macao's local specialties. At the end of the day, you can go shopping in the Grand Canal shopping center on the third floor of the Venetian Hotel. There are many brands in it, including high-end and people-friendly ones, and food and clothing are basically covered. After shopping, you can take the hotel free bus directly to the port.

4.

(1) Workload = number of people x average work efficiency × Working hours

(2) working time = workload ÷ Per capita work efficiency

(3) work efficiency per capita = workload ÷ Number of people x working hours per person)

If a work is completed in several stages, then the sum of the workload in these stages is equal to 1, which is the basis of common equations.

If a work is completed in a hour, then a's workload can be regarded as 1, the working time is a hour, and the working efficiency is 1 / A, The efficiency of a is 1 / 2 of B

5. Take Huatanshan bus at Daihu Road station and get off at wangxianxiang

6. Engineering quantity: it refers to the engineering quantity of each sub project or structural member expressed in natural measurement unit or physical measurement unit. For example: concrete is measured in square meters, steel is measured in tons, and floor tiles are measured in square meters<

workload: refers to the amount of work content, such as "heavy workload today", "heavy workload of this matter" and so on.

7. Answer: A is superimposed on B, and the pressure of B on the horizontal ground is numerically equal to the sum of the gravity of a and B
analysis:
isolate B, analyze the force of B in the vertical direction: downward gravity g & 8322; And the pressure of a on B, upward supported by the ground. Where the pressure value of a to B is equal to the weight g of A;. Therefore,
F branch = G & # 8321+ G₂
because f-pressure and f-branch are interaction forces, the magnitude is equal. Therefore,
b pressure on the ground is:
f pressure = G & # 8321+ G₂
2. The friction between B and the ground is:
F= μ&# 8322;( G₁+ G₂).

8. First of all, Sony PCM D100 will be removed because XLR is not supported. Recording function is relatively weak, you can't use many things, including your multi track recording

LS100 is much more expensive than dr100mkii, about one-third of them, but they have similar functions, even dr100mkii is better

can be made into mic, even connected to the camera. But I haven't burned the recorder for a long time, so I can only help you. Specifically, you'd better search the evaluation of each model. But I am sure that PCM D100 will not meet your requirements. Many people buy the D100 to listen without damage. The recording comes with a gift.... If you don't support XLR recording, you won't be satisfied with the sound quality.

9. Automatic reagent addition, automatic oil bath heating, automatic stirring, automatic digestion, automatic cooling, automatic determination of titration end point, automatic report generation

10.

at point a, you can take bus 753, 703, 710, get off at the political and legal building station, and then walk about 50 meters
