    Answer:

    B. Spring balance – a device used for measuring the weight or force of gravity acting on an object.

    Explanation:

    A Force is any interaction that changes the motion or position of an obkpjectbthatbit is interacting with. Whenever there is an interaction between two objects, there is a force exerted by each of the objects on one themselves.

    Forces are generally divided into contact forces and non-contact over field forces.

    In contact forces, the two objects physically in contact with each other. Examples of contact forces are push or pull forces, frictional forces, tensional forces, spring forces, etc.

    Non-contact forces are forces in which the two objects interacting do no need to be physically in contact with one another. Examples include, gravitational forces, magnetic forces, electrical forces, etc.

    Instruments used in measuring forces are known as force gauges.

    From the instruments listed above:

    A. A ruler is an instrument used in measuring length

    B. Spring balance is a device used for measuring the weight or force of gravity acting on an object.

    C. A thermometer is an instrument used in measuring temperature

    D. A windbvane is an instrument used in measuring wind direction.
