What relationship between the mass of each other and its motion after the collision do you observe? How do Newtons laws help explain your observations? remember that the action and reaction forces are equal in any collision if the action and reaction forces are equal then why do bumper cars that are of different masses react differently

What is the difference between electrically neutral objects and electrically charged objects

All the simple machines make work easier to do by changing the or of a force. a. size; type b. work; type c. size; direction d. type; direction

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
