Answer:
Conceptual or planning design phase.
Explanation:
Construction management have following phases
Phase 1 :Conceptual or planning design phase.
Phase 2 : Engineering and design phase.
Phase 3 :Procurement phase.
Phase 4 :Execution phase.
Phase 5 :Operation and maintenance phase.
These all phases running in a proper sequence .So at the begging of construction the first phase is conceptual or planning phase.
Answer:
a)A constant volume process is called isochoric process.
b)Yes
c)Work =0
Explanation:
Isochoric process:
A constant volume process is called isochoric process.
In constant volume process work done on the system or work done by the system will remain zero .Because we know that work done give as
work = PΔV
Where P is pressure and ΔV is the change in volume.
For constant volume process ΔV = 0⇒ Work =0
Yes heat transfer can be take place in isochoric process.Because we know that temperature difference leads to transfer of heat.
Given that
Initial P=10 MPa
Final pressure =15 MPa
Volume = 100 L
Here volume of gas is constant so the work work done will be zero.
Determine whether w is in the span of the given vectors v1; v2; : : : vn
. If your answer is yes, write w as a linear combination of the vectors v1; v2; : : : vn and enter the coefficients as entries of the matrix as instructed is given below
Explanation:
1.Vector to be in the span means means that it contain every element of said vector space it spans. So if a set of vectors A spans the vector space B, you can use linear combinations of the vectors in A to generate any vector in B because every vector in B is within the span of the vectors in A.
2.And thus v3 is in Span{v1, v2}. On the other hand, IF all solutions have c3 = 0, then for the same reason we may never write v3 as a sum of v1, v2 with weights. Thus, v3 is NOT in Span{v1, v2}.
3.In the theory of vector spaces, a set of vectors is said to be linearly dependent if at least one of the vectors in the set can be defined as a linear combination of the others; if no vector in the set can be written in this way, then the vectors are said to be linearly independent.
4.Given a set of vectors, you can determine if they are linearly independent by writing the vectors as the columns of the matrix A, and solving Ax = 0. If there are any non-zero solutions, then the vectors are linearly dependent. If the only solution is x = 0, then they are linearly independent.
