blagie [28]

Answer:

Louder music corresponds to more beer consumption. But this doesn't provide evidence that louder music can causes people to drink more beer.

Explanation:

The louder music does not cause people to drink more beer. There is a spurious correlation between drinking beer and Loud music because of the presence of confounding variable Social which is the interaction in the bar. The people at the bar are not able to talk to each other more because of the presence of loud noise or music. So, they are forced to drink beer more rather than talking during their stay at the bar.

Ilia_Sergeevich [38]

Answer:

The less-dense soda is the diet Dr. Pepper soda

Explanation:

density refers to how tightly packed together the molecules of an object is. The tighter the packing, the denser the object. For example, a piece of rock is denser than a piece of foam, because the molecules making up the rock are more tightly packed than the molecules making up the foam hence it is denser. In our example, an object that is denser than water will displace the molecules of water because it is heavier than water, hence it will sink, while an object that is less dense than water will float because the object is not heavy enough to displace the water molecules. Hence, the diet Dr. Pepper soda floats because the molecules are less dense than water and the regular Dr. Pepper soda sinks because the molecules are denser than water.
