Answer:
Workdone, w = 68.935 kJ
Explanation:
m1h1 + m2h2 + Q = m3h3 - Wc
Final mass of mixture,
m3 = m1 + m2 = 5kg
p1V1 = m1R1T1
p2V2 = m2R2T2
Since they are at 1:1,
V1 = V2 and R1 = R2
Comparing equations,
p1/p2 = (m1/m2) x (T1/T2)
m1/m2 = (100/200) x ((50 + 273)/(25+273))
m1/m2 = 0.542
m1 = 0.542m2
m3 = m1 + m2
5 = m2 + 0.542m2
m2 = 3.243kg
m1 = 1.757 kg
Workdone is given as,
Wc = m3h3 - m1h1 - m2h2
h = Cp x T, since air is an ideal gas
Cp = 1.005kJ/kGK
Wc = (5 x 1.005 x (55+273)) - (1.757 x 1.005 x 298) -(3.243 x 1.005 x 323)
Wc = 68.935 kJ
Answer:
It's one of the key standards of science, and it's critical to the point that it has become data a significant number of us underestimate. Realizing that every single living thing are comprised of cells permits us to see how creatures are made, develop, and kick the bucket. That data encourages us see how new life is made, why living beings take the structure they do, how malignant growth spreads, how maladies can be overseen, and that's only the tip of the iceberg. Cells even assist us with understanding principal issues, for example, life and passing: a creature whose cells are living is viewed as alive, while one whose cells are dead is viewed as dead. Illness, how creatures develop, and passing were substantially more of a puzzle contrasted with what we know today.
Explanation:
The cell theory is one of the primary hypotheses of science. It has three primary parts:
- Every single living thing are comprised of cells.
- Cells are the fundamental structure squares of life.
- All cells originate from previous cells made through the procedure of cell division.
As our logical information has expanded after some time, extra parts have been added to the theory. Schleiden and Schwann, just as Virchow, are for the most part observed as the organizers of the cell theory, because of their spearheading logical work during the 1800s. The cell theory is significant in light of the fact that it influences about each part of science, from our comprehension of life and passing, to how we oversee ailments, and the sky is the limit from there.
Different pieces of the cell theory since they weren't a piece of the first definition, yet it's as yet valuable to know about them:
- Vitality stream happens inside cells.
- Innate data is passed from cell to cell.
- All cells have a similar fundamental substance piece.
Answer:
γ
=0.01, P=248 kN
Explanation:
Given Data:
displacement = 2mm ;
height = 200mm ;
l = 400mm ;
w = 100 ;
G = 620 MPa = 620 N//mm²; 1MPa = 1N//mm²
a. Average Shear Strain:
The average shear strain can be determined by dividing the total displacement of plate by height
γ = displacement / total height
= 2/200 = 0.01
b. Force P on upper plate:
Now, as we know that force per unit area equals to stress
τ = P/A
Also, τ = Gγ
By comapring both equations, we get
P/A = Gγ ------------ eq(1)
First we need to calculate total area,
A = l*w = 400 * 100= 4*10^4mm²
By putting the values in equation 1, we get
P/40000 = 620 * 0.01
P = 248000 N or 2.48 *10^5 N or 248 kN

Answer:
The option that identifies why the bicycle cannot yet be created as a model in the scenario is;
Suzanne forgot to include the exact units of measurement that should be used
Explanation:
The design sketch turned over to the team that will work on the prototype by Suzanne should present all aspects of the design that will enable others working on the design and that make use of the sketch to have a clear understanding of what is required of them
Given that Suzanne has included the numbers that explain the relationship between the sketch and the real world object, the scale that shows the ratios and proportions of the sketch and the actual bicycle has been provided, however, given that the the machinist still need more information, the units of the measurement indicated in the drawing was not included, therefore, the actual dimensions and size that gives the length of the parts of the sketch and of the prototype to be made cannot be determined.
