now answer no.5 is



Both pistons P1 and P2 are hydraulically coupled. Hence,  
according to the Pascal's law, the pressure exerted to the working fluid must be equal for both pistons.  

Pressure = Force / Area 
P = F/A

As per question, 
P1 = F1/A1 (for piston 1) 

P2 = F2/A2 (for piston 2) 

Since, P1 = P2
F2 = (F1/A1) * A2

A2/A1 = [pi*{(50^2)/4}] ÷ [pi*{(10^2)/4}] = 25

F2 = F1 * 25 = 25 N 

I hope it helps. 


PLEASE MARK THIS AS BRAINLIEST...

Answer:The outer layer of fabric does get hotter because the black color absorbs more heat. ... A black body absorbs almost all the wavelengths of lightreceived by it(hence the color) and awhite colored body on the other hand reflects all(or most of) the wavelengths of light falling on it
