Answer:
Final mass=0.89kg
Final pressure=5.6bar
Explanation:
To find mass,m=v/v1
But v1=vf + x(vg-vf)
Vf= 0.001093m^3/kg
Vg= 0.3748m^3/kg
V1= 0.001093+0.5(0.3748-0.001093)
V1= 0.225m^3/kg
M= 0.20/0.225 =0.89kg
Final pressure will be:
V/V1= P/P1 
Cross multiply 
VP1=V1P
P1= 0.225×5/0.2
P1=:5.6 bar
 
        
             
        
        
        
Answer:
C
Explanation:
horizintal speed stays same
only vertical speed changes
so H speed will stay 30 m/s
 
        
             
        
        
        
I think answer should be d. Please give me brainlest let me know if it’s correct
