Answer 1

The correct answer is (b) Mechanical weighers

The explanation is: Mechanical weigher is commonly used all over world. This based on mechanical principle. This works on a lever system mounted on knife edges and bearings that connected to a resistant like a spring or pendulum. The resultant value obtained by multiplication of load and speed values is displayed by a digital counter.
