Amiddle-aged man typically has poorer hearing than a middle-aged woman. in one case a woman can just begin to hear a musical tone, while a man can just begin to hear the tone only when its intensity level is increased by 9.4 db relative to the just-audible intensity level for the woman. what is the ratio of the sound intensity just detected by the man to the sound intensity just detected by the woman? (level just detected by man / level just detected by woman)

Suppose a soccer ball is kicked from the ground at an angle 20.0º above the horizontal at 8.00 m/s. the y-velocity is determined to be 2.74 m/s. how long will the ball be in the air? assume the ball lands at the same height at which it was kicked.

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)

Does the distance travelled by an oscillating mass between times t=0 and t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanation.
