A mother finds her daughter’s mug of hot cocoa on a table an hour after she had been drinking it. As the mother pours out the cocoa, she sees brown solids in the bottom of the mug. How can this be explained?(1 point) The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went up.

All dissolved substances will come out of solution over time. If the mother waits long enough, then all of the powder will appear at the bottom of the mug.

The cocoa was mixed with hot water, but some cocoa settled as it cooled because the solubility went down.

This would only happen if too much cocoa powder was added in the first place, because the solubility should not change.

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
