So go on from where you left off ... take the formula you wrote (correctly),
plug in the numbers for mass and volume, and find the density. You can do it !
Because lava is in the center and lavas hot
The motion of objects w mass n velocity.
This is false. Even though the first part is true, the second isn't because morals and values are simply widely accepted opinions that most humans have, and you can't test opinions with the scientific method, only facts!
