Answer:
A RCRA characteristic hazardous waste is a solid waste that exhibits at least one of four characteristics defined in 40 CFR Part 261 subpart C — ignitability (D001), corrosivity (D002), reactivity (D003), and toxicity (D004 - D043). combustible, or have a flash point less than 60 °C (140 °F).
Answer:
Made of Silicon.
Explanation:
A diode is a semiconductor device use in mostly electronic appliances. It is two terminals device consisting of a P-N junction formed either in Germanium or silicon crystal.
Diode can be forward biased or reverse biased.
When a diode is forward biased and the applied voltage is increased from zero, hardly any current flows through the device in the beginning.
It is so because the external voltage is being opposed by the internal barrier voltage whose value is 0.7v for silicon and 0.3v for germanium.
If you measure 0.7 V across a diode, the diode is probably therefore made of Silicon.
Answer:
S = 172.69 J/K
Explanation:
For a closed system, the entropy is given as the natural logarithm of microstates.
The number of particles (grains of sand); N = 25
The number of boxes (compartments); M = 1000
Entropy is the logarithm of number of microstates; Thus,
S = In ψ
However, the number of microstates is given by the formula;
ψ = Mⁿ
Thus, S = In Mⁿ
Plugging in the relevant values to obtain;
S = In (1000)^(25)
S = 172.69 J/K
Answer:
a).Control volume
b). 
= 502.416 J/kg-K
c). 
= 4.187 kJ/kg-K
d). 
= 87.91°C
Explanation:
a). It is a control volume system because mass is varying in the system.
b). Specific heat of nickel is = 502.416 J/kg-K
c). Specific heat of water is = 4.187 kJ/kg-K
d).We know that
net energy transfer = change in internal energy
= 87.91°C
