An acorn at rest falls from an oak tree. The acorn hits the ground with a velocity of 29 m/s. How long did it take the acorn to land? Remember
g=9.8m/s2. DO NOT round numbers. Include units in your answer otherwise it
will be marked wrong.
Whoever answers this question will be the brainliest!!

Evaporation: this is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). water vapour droplets join together to make clouds! condensation: this is when water vapour in the air cools down and turns back into liquid water.

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
