Answer:
<em>d. floor spans exceed that which is economical with site-cast or hollow-core slabs and exceed 60 feet.</em>
<em></em>
Explanation:
<em>
Double tee slabs are prestressed concrete castings usually about 100 m to 150 m long</em>. <em>They are usually used in the construction industry in structures requiring a long floor span (or roof span) exceeding 60 feet in length, that is required to bear additional load (additional load carrying capability</em>). Double tee slabs are usually employed in construction because they shorten construction time. reduce congestion at the construction site, and also reduce construction cost.
<em>They are the required choice in construction when the cost of site casting or hollow-core slabs is no longer economical due to the length of the structure exceeding 60 feet.</em>
Answer:
the voltage drops will have the ratio 2 : 1
Explanation:
Assuming the loads have the same power factor, the voltage drop will be proportional to the load impedance. The loads have a ratio of 8 : 4 = 2 : 1, so the voltage drops will have a ratio of 2 : 1.
__
We assume the number associated with the load is representative of its impedance (not admittance, or some other measure).

Suitable for under and over-ground usage alike, 25mm 4 Core Armored Cable is a dust and waterproof variant of electrical cable that is commonly found within powered networks and supplying mains electricity to a large variety of devices, both domestic and industrial.
I think the answer is C) 0.25v I’m not sure tho
Parallel hookups increase amp hour capacity but voltage remains the same... 1.5 volts
Series the two and voltage is 3.0 volts.
