Where is the second level code of Ethereum

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. This should be combined with the specific situation. The pressure related to friction is the pressure on the contact surface. At this time, the two objects in contact are subjected to the pressure of equal size and opposite direction

7. 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.

8. Should be to take the bus to Daihu Road station, the specific train number and time do not know.

9. 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).
