Had to look for the options and here is my answer. What happens when the fluid discharge of an air-operated reciprocating pump is shut, this will cause the pump to OVERSTROKE. Overstroke happens when the engine is switching in a normally-closed manner.  
        
                    
             
        
        
        
Answer:
2.61 atm
Ley de Boyle
Explanation:
 = Presión inicial = 0.96 atm
 = Presión inicial = 0.96 atm
 = Presión final
 = Presión final
 = Volumen inicial = 95 mL
 = Volumen inicial = 95 mL
 = Volumen final = 35 mL
 = Volumen final = 35 mL
En este problema usaremos la ley de Boyle.

La presión ejercida sobre el émbolo para reducir su volumen es de 2.61 atm.

Answer:
Explained
Explanation:
Resistance R in a current flow through an object is given by 

ρ = resistivity of the material 
L= length of the object 
A=  area of cross section
clearly resistance is directly dependent on length of the object.This means greater the length larger will be resistance to current. 
thermal resistance R_th is given by 

L= length of the object 
A=  area of cross section
K = Conductivity of the material 
thermal resistance is also is directly dependent on length of the object.This means greater the length larger will be resistance to current.
