Q:2009 and 2010 construction of secondary construction division of the exam questions and answers, Jiqiu ~!

(Construction project) single multiple choice questions (a total of 20 questions, each question 1 points

Q:Would like to ask you under the construction of the rainy season, what measures ah? Teach the next sprinkle

reasonable organization of construction arrangements, so that sunny day to pay attention to outdoor work, rain arrangements for indoor work

Q:Sprinkling water on the construction helps to help reduce haze days

Construction site environmental protection measures are as follows: First, the dust management

Q:I'm still at school and if I got my scaffolding done at the start of the summer holidays it would have 6 weeks to heal, I would have to take it out once a week for 2 hours, would I experience any issues?

They take 9-12 months to heal and an unhealed piercing should never be removed. Yes, you would experience issues. It would likely close or shrink in size or if it somehow didn't then you could easily cause infection, irritation, prolonged healing, hypertrophic scarring...nothing you should be willing to risk. 6 weeks is far from being long enough.

Q:There is a 5.0 kg pail of paint to one side, as shown. How close to the end can he approach safely? Express your answer using two significant figures. If there is more than one answer, separate them by commas.

I am looking for as shown, as I am not psychic.

Q:What kind of insulation materials and equipment are allowed to be imported in China?

One of China Polypropylene board (EPS board) or extruded board (XPS board), extruded board special interface agent

Q:Seeking the Responsibility System of Safety Responsibility of Each Function Department Garden company for safe production permit

System, and to monitor the implementation of the situation

Q:a paintbrush falls from a scaffold takes 3 sec to hit the ground. How high is the scaffold? Explain pls!?

1) In three seconds the paintbrush accelerated to a speed of 96 feet/sec (ignoring air resistance) at a acceleration of 32 feet/sec/sec. 2) It started at a speed of zero, so the average speed for those three seconds was 48 feet/sec. 3) 3 seconds times 48 feet/sec. equals 144 feet.

Q:What would you like to ask?At what height do scaffolds have to be engineered?

At all heights...they are engineered as a system.

Q:Also if its possible part B wants to know A ball thrown vertically upward is caught bythe thrower after 2 s.Find the initial velocity of the ball. Theacceleration of gravity is 9.8 m/s2Answer in units of m/sFind the maximum height it reaches.Answer in units of m

Use, Vf = Vo + g * t With Vo = 0 , Vf = g * t = 9.8 m/s^2 * 3.39 s = 33.222 m/s. part B, use the same equation, but take into consideration to watch for direction and adopt a convention. As before we have considered +ve for downward direction. Now Vf = 0 0 = Vo + g * t. Vo = - 9.8 m/s^2 * 2 s = -19.6 m/s . Negative means upward direction according to the adopted convention.
