You have a length of tubing that is closed at one end. You cut the tubing into two pieces of unequal length, giving you a tube open at both ends and a tube closed at one end. You establish that the fundamental frequency for the new open tube is 333 Hz and for the new closed tube is 697 Hz. Determine the fundamental frequency for the original closed tube. (Use 343 m/s as the speed of sound.)

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
