Permeability & Permittivity of Free Space - Meaning

AI Thread Summary

Permeability and permittivity of free space are fundamental constants in physics that characterize how electric and magnetic fields interact with a vacuum. The term "aleatory" refers to randomness or chance, indicating that these constants are somewhat arbitrary based on the units chosen for measurement. Understanding these constants is crucial for fields like electromagnetism and telecommunications. Their definitions can be easily found through a quick internet search, providing clarity on their significance. These concepts are essential for grasping the behavior of electromagnetic waves in free space.

Yes, they are two constants that exist due to our aleatory chosen units.

Even if you don't have a dictionary, you clearly have all of the internet available.

Go to "google.com" and enter:

a) permittivity definition

b) Permeability definition

c) aleatory definition

Thread 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Understanding Forces and their Vector Components'

I was told forces are vectors so they can be divided into x and y components, but what about the normal force or the force of static friction? do you divide those into x and y components if say you had a block that was lying on an angled surface?
