Lets solve some physics facts here! Come we get to know :)

Thread for physics applicable facts in our daily life
Coz everything is physics

Example; why do we drink milk or juice using a straw and fact on why the rise of it in the straw?

Help Me The Fact Behind That!

Everything we deal with, in our daily life there is Physics behind or science in general!

Those Questions such as what you have asked, are simple minded Question is like someone asks,
why do we swallow when we eat!?

But of course i appreciate those Questions for beginners as it lays the fondations for Big Questions

For instance;

#How the Evolution works (Natural Selection)!?

#Why Universe expands at very high speed!?

#What was there before Big Bang!?

#How the Life Begins, is there a science behind it!?

#Are we the only Species in the entire Universe!?

So keep on studying to reach high level where you can be able to solve Complex Physics/Mathematics and come up with new technology that may be able to help the Human Civilization at large!

Lets me try.

We use straw to sip drinks because of hygiene, it is a hygienically unsafe drinking beverages in pots like blowing trumpets.🤣

What causes the drinks to get into one mouth while sipping is the atmospheric pressure.

Help Me The Fact Behind That!

Your question might have two possibility answers..

Firstly,juice rises through the straw due to the reason of capilality. As the ability of juice to rise through a narrow tube....

Secondly...the factor is due to pressure..as you pull out air from the straw, you create pressure difference between the lower part of the straw and the upper part, such leading juice to rise in the region where there is low pressure.

Oneni kitu kingine hiki;

Hello the Physics lovers, here is another simple puzzle to remind yourself of your mechanics prowess.😇


A ring shaped elastic rubber having Mass "M" is released to slide frictionlessly outside a round conical shape cylinder to a point where it stop outside the cylinder as shown in the diagram.

Qn, Find tension force "T" in the rubber at the stoppage point, given the conical apex angle theta.

OK
We will try...
Let:
T= Tension force
M=mass of rubber
mg= Upward force (weight)
a= acce due to gravity 9.6m/s2

T=mg cos(theta) - Ma (minus due to downward acceleration)

Good, at least you have tried and show that some how you understand the concept.

Hint; although this Qn may have different methods to solve but I prefere using the partial energy conservative law to other methods, it also involves a bit culculus;

Let the downward force by the rubber ring be Mg and the tension force in it be T, let the down distance moved by the ring be y and the the diameter and circumference of the ring at the point of stoppage be x and L respectivelly, therefore by the partial energy conservative law, given the apex angle of the cone (theta=B for simplicity). Here we go;

Mg∆y=T∆L ➡ Mgdy=TdL.....(1)

L=2πx.....(2), tan(B/2)=x/y........(3)

From the eqn 1, T=Mg dy/dL, dy/dL can be found from the eqns 2 and 3. to have the answer, ie dy/dL =dy/dx.dx/dL, when you are done then subst, into eqn1 for the final answer T.
