Concave.
A surface shaped in such a way that the center curves inward like this:
Convex.
A surface shaped in such a way that the center curves outward like this:
I just took the test I hope this helps. :)
Work= force*distance
Work= x*12
Force= mass*acceleration
Force= 5 kg*6
Force= 40 N
Work= 40×12
Work= 480 J (joules)
I think this is it
Thank you so much thank ya thank love you so so cute I just saw this
