A320 hz tuning fork is resonating in a closed tube on a day when the speed of sound is 335 m/s. what is the length of the closed tube?

0.26 m
0.24 m
0.96 m
1.05 m

The length of the closed tube is 1.05 m

Explanation:

Wave speed is defined as the product of its wavelength and frequency.

Mathematically,

where,

= length of the closed tube = ?

= frequency of the tuning fork = 320 Hz =

Speed of the sound wave = 335 m/s

Putting values in above equation, we get:

Hence, the length of the closed tube is 1.05 m

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
