A small hole is made at the bottom of a plastic cup. If it is filled with water and allowed to fall freely, will waterfall down from the hole?

Yes, because of both gravity and the fact that nothing is obstructing the hole.

It depends on how big the hole is.

Explanation:

If the hole is too big, the water will fall freely out of the cup. However, if it is just a small opening (from a needle, pencil/pen tip, etc.) the water pressure will be able to hold in the water.

i believe it is b. what was the cause of the big bang

hope this !

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
