AI Thread Summary
The total energy of a proton is three times its rest energy, indicating a total energy of 3E₀. To find the proton's rest energy in electronvolts (eV), the equation E = mc² can be used, where m is the proton's mass. The speed of the moving proton can be calculated using the relationship between total energy and momentum, factoring in relativistic effects. The proton's momentum can be determined using the equation p = mv/√(1 - v²/c²). Understanding these concepts is essential for solving the problem effectively.

the total energy of a proton is 3 times it rest energy.
-find the proton's rest energy in eV
-what is the speed of the moving proton?
-what is the proton's momentum?
please help me..i don't know how to solve it

welcome to pf!

hi nufa19! welcome to pf! :smile:

start by writing the equation that relates total energy and rest energy :wink:

(if you don't know it, look it up!)

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 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
