The answer should be D all of the above
I think the correct answer is b. Temperature is proportional to the average kinetic energy so when temperarure rises so will the average kinetic energy. I hope this helps. Let me know if anything is unclear.
Molar mass NaCl = 58 g
Mass of solute = 29 g
number of moles: mass of solute / molar mass
n = 29 / 58
n = 0.5 moles
hope this helps!
Answer:
Explanation:
(1) first part of solution: we know stress= Force/Area ; Force= 400lb and Area as given
(2) Second part of the solution its the standard formula for Hoop stress and the formula explains all the terms
(3) Third part of the solution we know Strain= (Change in length)/original length and also the strain are substituted in terms of strain and youngs modulus
Further explanation are given in the attach document.
