Suppose you harvested a large crop of grain this year. the grain is now in a pile and takes up an area of 50 m2 and is 2 m high. you have a silo that has an area of 15 m2 that is 3 m high. will all of the grain fit in this silo? if not, how much of the grain will remain outside of the silo? show your work

I'm pretty sure that the silo has the shape of a cylinder.
So its volume is

(area of the base) x (height) = (15 m²) x (3m) = 45 m³ .

I'm going to assume that the pile has taken the shape of a cone
on the ground, so its volume is

(1/3) x (area of the base) x (height)

= (1/3) x (50m²) x (2m) = 33-1/3 m³ .

The whole answer to the question rests on the exact shape of
the pile of grain on the ground. It could really help if somebody
could take a picture of the pile, so we could study the picture
here in Chicago, and estimate how closely the shape of the
pile resembles a cone.

If my assumption is valid, and the volume of grain in the pile
can be accurately calculated as the volume of a cone with the
same dimensions as the pile, then the grain will all fit in the silo
with no problem. The silo will still be only 74% full, and it'll still
have room for another 11-2/3 m³ of grain.

But if, say, the grain got wet and sticky as it was being poured
onto the pile, and the pile took the shape of a huge brick, then
its volume is (area of the base) x (height) = 100 m³ .
If that's the shape of the pile, then only 45% of it will fit into the
silo. The silo will be full and there'll still be 55 m³ of grain left
out on the ground to rot.

With the information that they sent to us up here in Chicago,
we simply don't know.

Answer from: Quest

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like $\frac{1}{3}$ . (i crazy)

most famous scientist who contributed to this physics are:

max planckalbert einsteinerwin schrödingermany

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

superposition (where 1 thing can be this and that at the same time),entanglement (where two particles are seemingly connected by some sort of unknown (or known) force, energy, matter (i know all that can be the same at least it was at the beginning)

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
