Explanation:
Below is an attachment containing the solution.
For the velocity graph: start at 0s and 4m/s and draw a straight line to 2s and 2 m/s. Then draw a straight horizontal line to 4s and 2m/s
For the acceleration graph: start with a horizontal line from 0s and 2m/s/s to 2s and 2m/s/s. The draw another line from 2 s and 0m/s/s to 4 s and 0m/s/s
true
Explanation:
this is because melting point and boiling point decreases down the group because they are held together by attractions between positive nuclei and delocalised electrons
Elastic
Explanation is that it is force which is snapping back
Over lava!
I’m pretty sure that’s the answer cuz I haven’t seen the movie in a hot minute!
