Pressure applied to an enclosed fluid is transmitted undiminished in all directions. This is used in:
AVenturi meters
BPaint brushes
CHydraulic brakes
DMercury barometers
Answer & Solution
Correct answer: C. Hydraulic brakes
1. This is Pascal's law.
2. Fluids transmit pressure to a larger piston.
3. Hydraulic lifts and brakes work this way.
