A physics teacher shoots a rifle at a 0.500 kg block of wood hanging on a string. The 8.0kg gun fired the 0.0250 kg bullet with a speed of 250. m/s. What is the velocity of the block of wood with the bullet inside?

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for

The rocks expand when there hot/warm  and contract when they are cold.

Inner peace.. jk it's  a stable electron configuration
