Answer:
b) False
Explanation:
Work done by a system is not a property because it doesn't define the system's state. Work is mechanical energy exchanged across the system's boundaries.
Permanent modular construction tends to fit the construction purposes that it was specifically designed for.
Answer:
Distance between manholes = 166.67 (Unit) (Approx)
Explanation:
Given:
Invert elevation = 2605
New Invert elevation = 2610
Grade % = 3% = 0.03
Find:
Distance between manholes
Computation:
Grade % = (Change in elevation)/Distance between objects
0.03 = (2610-2605)/Distance between manholes
0.03 = 5 / Distance between manholes
Distance between manholes = 166.67 (Unit) (Approx)
Answer:
the force of gravity (Fgrav) and the normal force (Fnorm).
Explanation:
Neglecting friction and air resistance, a roller coaster car will experience two forces:the force of gravity (Fgrav) and the normal force (Fnorm). The normal force is directed in a direction perpendicular to the track and the gravitational force is always directed downwards.
Answer:
0.5274 lagging.
Explanation:
So, we are given the following data or parameters or information which is what we need in order to solve this kind of question effectively. So, we have;
=> " For the given network:
ZR = 100 [Ω] , ZL = j124 [Ω], and ZC = - j89 [Ω]"
And we are asked to find the power factor. The power factor can be found or determined or calculated as;
7eq= 100 + j ( 24) (-89).
7eq = 124 × 89 - j89 × 100/ 100 + j35
7 eq= 133.81 L- 58.17.
Thus, the power factor is equal to;
=> Cos (58.17)= 0.5274 lagging.
Hence, the correct answer to this question is 0.5274 lagging.
