force temperature

1. this principle says that the buoyant force is equal to the weight of the displaced fluid.
2. what is the net torque acting on an object in rotational equilibrium?
3. rate at which distances is covered.
4. the measure of the tendency of a force to cause a rotational change.
5. force per unit area.
6. energy transferred between two objects because they have different temperatures.
7. the state an object is in when gravity is the only force acting on it.
8. when heat flows into an object, either the temperature will change or this will change.
9. this type of force is exerted by a fluid on an object wholly or partially submerged in the fluid.
10. a closed path for current to flow that contains a power source and an electrical device.

Explanation:

To solve the matching, we analyze each term:

• Weight: (Not fully visible, but assume based on physics concepts)
• Phase: (Relates to matter states, but let's match given defs)
• Buoyant: Def 9 (force by fluid on submerged object)
• Zero: Def 2 (net torque in rotational equilibrium is zero)
• Calorie: (Unit of heat, but def 6 is heat transfer, maybe later)
• Archimedes: Def 1 (Archimedes' principle)
• Torque: Def 4 (tendency of force to cause rotational change)
• Virtual: (Not in given defs yet, maybe later)
• Speed: Def 3 (rate of distance covered)
• Real: (Not in given defs yet)
• Pressure: Def 5 (force per unit area)
• Circuit: Def 10 (closed path for current)
• Energy: (Related to kinetic, etc., def 8 maybe? When heat flows, energy or temp changes)
• Kinetic: (Kinetic energy, part of energy)
• Liquid: (State of matter, phase maybe? But phase is a term, so phase - state, liquid - phase? Maybe phase matches with liquid's state? Not clear, but let's proceed with clear matches:
• Archimedes → 1
• Torque → 4
• Speed → 3
• Pressure → 5
• Circuit → 10
• Buoyant → 9
• Zero → 2
• Heat → 6 (energy transfer due to temp difference)
• Volume: (Not in defs yet)
• Resistance: (In circuit, but circuit is 10, resistance is part of circuit)
• Current: (In circuit)
• Lever - arm: (Related to torque, distance from axis)
• Free - fall: Def 7 (gravity only force)
• Vector: (Quantity with magnitude and direction)
• Frequency: (Cycles per unit time, not in defs yet)
• Force: (General force, torque is a force - related term)
• Temperature: (Related to heat, def 6 is heat transfer, temp is cause)

For the visible terms with clear defs:

• Archimedes: 1
• Torque: 4
• Speed: 3
• Pressure: 5
• Circuit: 10
• Buoyant: 9
• Zero: 2
• Heat: 6
• Free - fall: 7

(Note: Some terms like Virtual, Real, Volume, Resistance, Current, Lever - arm, Vector, Frequency, Force, Temperature, Kinetic, Liquid, Phase, Weight, Calorie need more context, but we match the clear ones.)

Answer:

• Archimedes: 1
• Torque: 4
• Speed: 3
• Pressure: 5
• Circuit: 10
• Buoyant: 9
• Zero: 2
• Heat: 6
• Free - fall: 7

(For other terms, more definitions are needed to complete, but the above are clear matches based on physics concepts and given definitions.)
