A388 hz tuning fork is resonating in a closed tube on a warm day when the speed of sound is 346 m/s. what is the length of the closed tube?

a. 0.89m
b. 1.12 m
c. 0.28m
d. 0.22m

!

A

Explanation:

because u are subtracting if this is from flvs that is what i did and it was right

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.
