A baseball player hits a baseball , changing its momentum by 15 kg* m s The net force on the ball is 7,100 N. How long does the bat maintain contact with the ball?

An object is 10. cm from the mirror, its height is 3.0 cm, and the focal length is 2.0 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1.33 -1.33 +0.75 -0.75

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.
