Musicians can use beats to tune their instruments. one flute is properly tuned and plays the musical note a at exactly 440 hz. a second player sounds the same note and hears that her instrument is slightly "flat" (that is, at too low a frequency). playing at the same time as the first flute, she hears one loud-soft-loud beat per second. what is the frequency of her instrument?

439 Hz

Explanation:

= Frequency of first wave = 440 Hz

F = Beat frequency = 1 Hz

= Frequency of the instrument

The beat frequency is the difference of the two waves which are interacting with each other

The frequency of the instrument is 439 Hz

b.

explanation:

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
