A kid with good form kicks a ball with a force of 10.0 N while making contact for 0.225 s. An adult with bad form kicks the ball with a force of 21.2 N while making contact for 0.102 s. What is the impulse, change of momentum, imparted by the kid?

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

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.)
