Answer: answers of science book is to help you
Explanation: if there are answer in a science book use them there for a reason
Answer: You're question is very vague... be more specific in the problem, what is it asking you to do?
Explanation: This shouldn't be under "Engineering" you should put it under "Mathematics" for a better result. Sorry for the mix up! Hope this helps! ^^
Answer:
aluminum bar carrying a higher load than steel bar
Explanation:
Given data;
steel abr
diameter = 5 mm
stress = 500 MPa
aluminium bar
diameter = 10 mm
stress = 150 MPa
we know
stress = laod/area
for steel bar
solving for P
P = 9817.47 N
for Aluminium bar
solving for P
P = 11790 N
aluminum bar carrying a higher load than steel bar
Answer:
c) Young's modulus Toughness.
Explanation:
The charpy impact test is well known in the Engineering field specifically in stress, strain and mechanical of fracture.
A theoretical definition is that the test determines the amount of energy absorbed by a material during fracture.
Answer: The number of gram of ammonia gas () contained in the a 3.0L vessel at 305 K with a pressure of 1.50 atm is 3.048 g.
Explanation:
Given: Volume = 3.0 L
Temperature = 305 K
Pressure = 1.50 atm
Formula used to calculate the number of moles is as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
It is known that moles is the mass of substance divided by its molar mass.
Hence, mass of ammonia gas (molar mass = 17.03 g/mol) is as follows.
Thus, we can conclude that the number of gram of ammonia gas () contained in the a 3.0L vessel at 305 K with a pressure of 1.50 atm is 3.048 g.
