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>
I think because if you’ve already turned it in they might as well grade asap instead of waiting
Answer:
A drivetrain allows a robot to be mobile by using wheels, tank treads, or another method. A drivetrain is sometimes referred to as a drive base. Identifying which kind of drivetrain to use is one of the first considerations when designing a robot.

Answer:
R min = 28.173 ohm
R max = 1.55 × 
ohm
Explanation:
given data
capacitor = 0.227 μF
charged to 5.03 V
potential difference across the plates = 0.833 V
handled effectively = 11.5 μs to 6.33 ms
solution
we know that resistance range of the resistor is express as
V(t) = 
...........1
so R will be
R = 
....................2
put here value
so for t min 11.5 μs
R = 
R min = 28.173 ohm
and
for t max 6.33 ms
R max = 
R max = 1.55 × ohm
