A shell explodes into two fragments, one fragment 25 times heavier than the other. If any gas from the explosion has negligible mass, then

a. the kinetic energy change of the heavier fragment is 25 times as great as the kinetic energy change of the lighter fragment.
b. the momentum change of the heavier fragment is 25 times as great as the momentum change of the lighter fragment.
c. the momentum change of the lighter fragment is 25 times as great as the momentum change of the heavier fragment.
d. the kinetic energy change of the lighter fragment is 25 times as great as the kinetic energy change of the heavier fragment.
e. the momentum change of the lighter fragment is exactly the same as the momentum change of the heavier fragment.

explanation:

b.a device that inputs heat into a cool object

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
