{'hydraulic brakes7': [0, 0, 0, 1], 'hydraulic lift': [0, 0, 0, 1], 'arc devices': [0, 0, 0, 1], 'fluids': [0, 0, 0, 1], 'pressure': [0, 0, 0, 1], 'force': [0, 0, 0, 2], 'momentum': [0, 1, 0, 3]}

In hydraulic brakes and hydraulic lifts, fluids are used for transmitting force. Let`s take a closer look at each option to understand why:

1. Force: This option is correct. Hydraulic systems work by exerting pressure on a fluid, which then transmits this force to another part of the system. In the case of hydraulic brakes, for example, when the driver applies force to the brake pedal, it creates pressure in the fluid, which then applies force to the brake pads, causing them to press against the brake discs and slow down the vehicle.

2. Momentum: This option is incorrect. Momentum refers to the quantity of motion of an object, and is not directly related to the operation of hydraulic brakes and lifts.

3. Pressure: This option is correct. As mentioned earlier, hydraulic systems rely on the creation and transmission of pressure through a fluid. This pressure allows the force to be transmitted and applied to various components of the system.

4. Power: This option is incorrect. Power is the rate at which work is done or energy is transferred. While hydraulic systems can provide power, the main focus is on the transmission of force through the use of fluids.

In summary, the correct answer is option 3, as hydraulic brakes and hydraulic lifts use fluids to transmit force through
