AI Thread Summary
To convert W²/NJHz to MKS units, start with the expression W²/NJHz. Substitute W with J/s, leading to (J/s)² in the numerator. This simplifies to J²/s², and substituting J with Nm gives (Nm)²/s². After canceling units, the final result simplifies to m/s, confirming the conversion is correct.

Just plug those values into the expression and cancel everything that can be canceled.
 
\frac{W^2}{NJHz} <br /> = \frac{(\frac{J}{s})^2}{NJ\frac{1}{s}} <br /> = \frac{\frac{J}{s}}{N} <br /> = \frac{Nm}{Ns} <br /> = \frac{m}{s}<br />

is this right?

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...

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}...
