If the benefit of talking to plants is the CO2 they get, has anyone heard of any studies to test if farting on plants will also make them grow better?

How do the hanging mass and rotating mass affect velocity/centripetal acceleration? You know the centripetal force apparatus where you use a rubber stopper (rotating mass) and washers (hanging mass)? Yeah i am talking about that. I am wondering if the hanging mass and rotating mass affects the velocity. I looked for velocity calculators like this one

http://hyperphysics.phy-astr.gsu.edu/hbase/cf.html#cfc

but the Mass field doesn't state if it includes both hanging/rotating mass so i am confused.

asking hypothetically or theoretically, i know there isn't anything like it in existence. But is there any theories, experiments, or advancements in such a technology? Is it in the realm of possibility that a car can move along and draw static from the air and use it to run itself?

What is the probability of having 3 girls and 3 boys?

If you do out every combination of 6 children:
BBBBBB
BBBBBG
BBBBGB
BBBBGG
BBBGBB etc..., you will find that there are 64 combinations, and 20 of them have 3 girls and 3 boys. (answer=20/64)
What is the mathematical equation to simplify this, as writing that out would take 15 minutes?

Please show the worked problem for the probability of 3 girls and 3 boys, and also for the probability of at least 4 girls. (answer for that one is 22/64)

Thank you

A cylindrical drill with radius 1 is used to bore a hole throught the center of a sphere of radius 2. Find the volume of the ring shaped solid that remains.

I know that you can't just subtract the volume of the cylinder, as that does not take into acount the rounded top and bottom. If you could help me set up this problem, I would really appreciate it.

Homework question, if you couldn't tell. My problem is that I don't know HOW to solve it with so little information, so if you could explain the steps I'd appreciate it!
