Description:

There's a giant blob monster attacking New York. Luckily, Shmoop isn't based in New York, so you don't need to worry about getting your fill of shmoopy test prep questions. Students in New York on the other hand, well....they've got bigger blobs to fry.

Thank you We sneak and here's your shmoop du jour
00:05
brought to you by blob monsters We've never seen one
00:08
but they probably looks something like we do after thanksgiving
00:11
dinner All right A giant blob monster is attacking new
00:15
york and suddenly doubles in mass if the original force

00:19
of gravitation exerted upon it is expressed as f which
00:23
of the following represents the new gravitational force after its
00:28
change in mass and here the pendulums happened All right
00:33
so we've got a block attacking new york The blob
00:35
actually isn't a very scary monster It's really Just a
00:38
big slow moving bunch of goo To answer this question
00:41
we need to know how to calculate the gravitational force
00:44
acting on an object and to find that force we
00:47
take the objects mass and multiply it by gravity like
00:51
f equals mg like that Now if we were in
00:53
a double mass the equation would now be force equals
00:58
two times mass times gravity or two mg which means
01:02
that the force exerted would be double no The correct
01:05
answer here is c to f but let's not devalue
01:09
Blob monsters Too much after all a monster self worth
01:12
Is often based on how scary it is And we 00:01:14.89 --> [endTime] wouldn't want to hurt its feelings
