The answer is choice C
Explanation:
As during construction ,the site is cleared for all debris before laying out the foundation. Even the sewer lines are dug out .
So it will be useful for the construction crews to connect the pipes to the sewer lines before the foundation is poured.
But usually the steps take in construction activity is:- first the site is cleared for the foundation to be poured and once the foundation wall is set , then all utilities , including plumbing and electrical activities are done.,
After this process is over, the city inspector comes to check whether the foundation has been laid down as per the code of construction.
Only after that the rest of the construction activity follows through.
Its safe because it isn't something with electricity
Answer: cotton and/or known as Cotton rope
Explanation: It is a very weak fiber that has less strength than cotton. So its typically very weak
Answer:
acceleration = 24.23 ms⁻¹
Explanation:
Let's gather the data:
The acceleration of the car is given by a = 0.5 
The acceleration is the change in the speed in relation to time. In other words:
= a = a = 0.5 ...1
Solving the differential equation yields:
v = 0.5 + C₁
Initial conditions : 0 = 0.5 
+ C₁
C₁ = -5
at any time t, the velocity is: v= 0.5- 5
Solving for distance, s = 0. 5 - 0.5 t - 0.5
18 = 0.5 - 0.5 t - 0.5
t = 3.71 s
Substitute t = 3.71 s
v= 0.5- 5
= 19.85 m/s
a = 0.5 ...1
= 20.3531
an = 
= 
= 13.1382
Magnitude of acceleration = 
= 
= 24.23 ms⁻¹ Ans
