I think it's The fossil record. The same animal fossil is in Africa and South America. The animal could have not swim across so its the fossil record
I’m pretty sure u have it right
Elastic potential energy is equal to the force times the distance of movement. Elastic potential energy = force x distance of displacement. Because the force is = spring constant x displacement, then the Elastic potential energy = spring constant x displacement squared.
the awnser to ur question is D
The internal pressure increases as the gas is heated
