Answer:
LFNC-A
Explanation:
Liquidtight Flexible Non-Metallic Conduit Type LFNC-A is a layered raceway of circular cross section with a smooth flexibly polyvinyl chloride (PVC) inner layer with a reinforcing layer covered with a flexible polyvinyl chloride (PVC) jacket.
Hope this helps!! You were correct for Question 9 but incorrect for Question 10. Yes, the value comes out to be 62.4 kJ but watch out for your signs! It is definitely a positive number. Therefore, you have to consider your other choices. When I converted the 62.4 kJ to J, I found an option that matches my answer.
A. Molar Mass
Explanation:
Gram molecular mass is the mass in grams of one mole of a molecular substance. Gram molecular mass is the same as molar mass.
Answer:
The mass of the bar is approximately 0.33 g.
Explanation:
q (heat in joules) = 1000 J
c (specific heat capacity) = 52 J/g°C
ΔT (change in temperature) = 80 - 22 = 58°C.
m (mass in grams) = ?
m = q / cΔT
m = 1000 J / (52 J/g°C) (58°C)
m = 0.33 g
hope this helps and is right!! p.s. i really need brainliest :)
