A square cross-sectional magnet has a pole strength of 110' Wb and cross-sectional area of 20 mm 20 mm. What would probably be the
strength at a distance of 100 mm from the unit pole in air?​

How is the gravitational force related to the distance between two objects?

The frequency of a tuning fork can be found by the method shown. a long tube open at both ends is submerged in a beaker of water, and the vibrating tuning fork is placed near the top of the tube. the length l of the air column is adjusted by moving the tube vertically. the sound waves generated by the fork are reinforced when the length of the air column corresponds to one of the resonant frequencies of the tube. the smallest value for l for which a peak occurs in sound intensity is 7 cm. l what is the frequency of the tuning fork? the speed of sound in air is 345 m/s. answer in units of hz
