To kick a football, the kicker rotates his leg about the hip joint. If the velocity of the the kicker's shoe is 38.9 m/s and the hip joint is 1.21 m from the tip of the shoe, what is the shoe tip's angular velocity

Asher cycles 12 miles in 16 hours. what is his speed?

Which model displays the change in a gas when the temperature of the gaseous system decreases?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
