Adeer is running from a mountain lion when it encounters a fence that is 1.50 m high. seeing the fence, the deer jumps, leaving the ground at a speed of 13.0 m/s and angle of 29.0º when it is a distance of 2.50 m from the fence. (a) by how much does the deer either clear or miss clearing the fence? (b) just before reaching the fence, is the deer rising or falling through the air?

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
