Question

question 9 of 10
the energy applied to cause vibration can be in the form of air pressure, a stick, a bow, or electricity.
a. true
b. false

Explanation:

To determine the answer, we analyze the statement. Air pressure (e.g., in wind instruments), a stick (e.g., striking a drum), a bow (e.g., for a violin), and electricity (e.g., in electronic instruments) are all valid forms of energy to cause vibration in different musical or vibrating systems. So the statement is true.

A. True
