Answer:
For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature. so it's B
Explanation:
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: the absolute static pressure in the gas cylinder is 82.23596 kPa
Explanation:
Given that;
patm = 79 kPa, h = 13 in of H₂O,
A sketch of the problem is uploaded along this answer.
Now
pA = patm + 13 in of H₂O ( h × density × g )
pA= 79 + (13 × 0.0254 × 9.8 × 1000/1000)
pA = 82.23596 kPa
the absolute static pressure in the gas cylinder is 82.23596 kPa
Answer:
D. The damage it causes is irreversible
Explanation:
Silicosis is a long term lung disease caused by crystalline silica dust inhalation. There is no cure, and once the damage is done it cannot be reversed.
------------------
Like stated above, the damage is irreversible. Option A is incorrect.
Construction workers are constantly moving to build whatever they're working on. The disease will make it hard to breathe and will have a heavy effect on their lungs, preventing them from properly doing their jobs. Additionally, it's possible to get the disease from this job since you're constantly inhaling dust particles.
Silicosis does major damage to the lungs. The dust particles are attacked by the immune system which causes inflammation and eventually leads to areas of hardened and scarred lung tissue.
Thus, the best option is D.
hope this helps :)
Answer:
(b) False
Explanation:
The specific internal energy of the system does not depend on the path of the process, it is a state function means its depend on only on the initial and the final position it does not depend on the path which it follow in the process.Internal energy is associated with the random motion of the molecules.
So it is false statement as internal energy is not a path function
