Solid Mixtures There are a number of mixtures that are solid at room tem perature . Brass is a mixture of copper and zinc . Soil (dirt ) is also a solid mixture at room temperature . Which is homoge nous , brass or soil ? What test would you use to determine this ?

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
