Answer: It formed when lava cooled quickly aboveground.
Explanation: Cause its right
Answer:42.43m/s
Explanation:According to vf=vi+at, we can calculate it since v0 equals to 0. vf=0+9.8m/s^2*4.33s= 42.434m/s
gravity? I am not completly sure but this is my best guess
C metal. most metals are a conductor which an electric current is attracted to.
The kinetic energy of an object is given by:

where m is the mass of the object and v its speed. The ball in this problem has a mass of m=0.2 kg and a kinetic energy of K=40 J, so we can rearrange the previous equation to find its speed:
