Carbon is not used as semiconductor it has 4 valence electrons in it valence shell but the energy gap is very small it will conduct electricity even at room temperature ,the size of carbon is very small .
Answer:
It value is range varies from 0.45 for Soth Asia, 1.1 for middle east and North America and 2.2 kg/capita/day for OECD countries.
Explanation:
Solid waste generation is about in the range of 63 million tonnes per year in the North Africa and Middle East . Per capita waste generation is 0.15 to 5.7 kilogram in a day for 1 person, and the average is of about 1.1 kg/capita/day.
Its about 571 million tonnes solid waste in a year is generated by The OECD countries . The value of per capita is ranging about 1.2 to 3.7 kg in a day for a person with the average value of about 2.2 kg per capita per day
Its about 70 million tonnes of solid waste in a year is generated by The South Asian countries . The value of per capita is ranging from 0.12 to 5.1 kg in a day for a person with the average value of about 0.45 kg/capita/day
Answer:
<em>181 °C</em>
<em></em>
Explanation:
Initial pressure = 100 kPa
Initial temperature = 30 °C = 30 + 273 K = 303 K
Final pressure = 1200 kPa
Final temperature = ?
n = 1.2
For a polytropic process, we use the relationship
(/ ) = (/)^γ
where γ = (n-1)/n
γ = (1.2-1)/1.2 = 0.1667
substituting into the equation, we have
(/303) = (1200/100)^0.1667
/303 = 12^0.1667
/303 = 1.513
= 300 x 1.513 = 453.9 K
==> 453.9 - 273 = 180.9 ≅ <em>181 °C</em>
Answer:
theoretical fracture strength = 16919.98 MPa
Explanation:
given data
Length (L) = 0.28 mm = 0.28 × 10⁻³ m
radius of curvature (r) = 0.002 mm = 0.002 × 10⁻³ m
Stress (s₀) = 1430 MPa = 1430 × 10⁶ Pa
solution
we get here theoretical fracture strength s that is express as
theoretical fracture strength = .............................1
put here value and we get
theoretical fracture strength =
theoretical fracture strength =
theoretical fracture strength = 16919.98 MPa
