Research the instrument and explain how it works in terms of sound production and resonance. Describe how a musician can vary the pitch and loudness of the notes. Explain why different types of musical instruments sound different, even though they play the same notes.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
