Answer:
0.1047N 
Explanation:
To solve this problem we must remember the conversion factors, remembering that 1 revolution equals 2π radians and 1min equals 60s

in conclusion, to know how many rad / s an element rotates which is expressed in Rev / min we must only multiply by 0.1047
 
        
             
        
        
        
3-SAT ≤p TSP
If P ¹ NP, then no NP-complete problem can be solved in polynomial time.
both the statements are true.
<u>Explanation:</u>
- 3-SAT ≤p TSP due to any  complete problem of NP to other problem by exits of reductions. 
- If P ¹ NP, then 3-SAT ≤p 2-SAT are the polynomial time algorithm are not for 3-SAT. In P, 2-SAT is found, 3- SAT polynomial time algorithm implies the exit of reductions. 3 SAT does not have polynomial time algorithm when P≠NP.
- If P ¹ NP, then no NP-complete problem can be solved in polynomial time. because for the NP complete problem individually gets the polynomial time algorithm for the others. It may be in P for all the problems, the implication of latter is P≠NP.
 
        
             
        
        
        
Answer:
The value of heat transferred watt per foot length Q = 54.78 Watt per foot length.
Explanation:
Diameter of pipe = 2 in = 0.0508 m
Steam temperature  = 300 F  = 422.04 K
 = 300 F  = 422.04 K
Duct temperature  = 70 F = 294.26 K
 = 70 F = 294.26 K
Emmisivity of surface 1 = 0.79
Emmisivity of surface 2 = 0.276
Net emmisivity of both surfaces ∈ = 0.25 
Stefan volazman constant  = 5.67 ×
 = 5.67 ×  
 
Heat transfer  per foot length is given by 
Q = ∈  A (
 A (  ) ------ (1)
 ) ------ (1)
Put all the values in equation (1) , we get
Q = 0.25 × 5.67 ×  × 3.14 × 0.0508 × 1 × (
 × 3.14 × 0.0508 × 1 × (  )
 )
Q = 54.78 Watt per foot.
This is the value of heat transferred watt per foot length.
 
        
             
        
        
        
Answer:
ICP -OES stand for inductively coupled plasma optical emission spectroscopy
Explanation:
It is techniques that known as trace level technique which help to identify and quantify the element present in sample by using spectra emission.
The analysis process include desolvates, ionization and excitation of the sample. The sample is identify by analyzing the emission line from it and quantify by analyzing the intensity of same emission lines.
