Answer:
The index of refraction of the liquid is 1.35.
Explanation:
It is given that,
Critical angle for a certain air-liquid surface, 
Let n₁ is the refractive index of liquid and n₂ is the refractive index of air, n₂ =1
Using Snell's law for air liquid interface as :
So, the index of refraction of the liquid is 1.35. Hence, this is the required solution.
Answer:
The load that can be lifted is equal to the weight W = F2A1/A2
Explanation:
According to Pascal principle which states that the pressure applied to a liquid confined in a container will be transmitted equally to all other parts of the container.
Since pressure = Force/Area
The force F2 applied at one end of the piston will generate a pressure of F2/A2. This pressure generated will be transmitted to the other end of the piston of area A1 to lift the load through a distance.
The piston where the load is will experience an upward force F1 which is equal to Pressure × Area.
The pressure experienced by the load is applied by force F2.
Force on the load = (Pressure exerted by Force F2) × Area at the larger end A1
Force on the load = F2/A2 × A1
Since the load experiences a weight W
The weight will be equal to the force on the load which is to be lifted i.e W =Force on the load.
W = F2A1/A2
The load that can be lifted is equal to the weight W = F2A1/A2
The answer is the diameter of the cam shaft.
This is used to compute for the area of the circle so you can multiply it with the rocker ratio to get maximum amount of weight the valve can lift.
Gpe = mgh
Gpe = 500*10*25
Gpe = 125000J
