AI Thread Summary

When converting measurement units, the uncertainty remains consistent across unit changes. For example, a length of 8.25 cm with an uncertainty of +/- 0.05 cm translates to 0.0825 m with an uncertainty of +/- 0.0005 m. The conversion does not introduce additional uncertainty; it simply translates the existing measurement. Therefore, the method of converting uncertainty is straightforward and maintains the same relative precision. Accurate unit conversion is essential for ensuring clarity in measurements.

Here's my value: length: 8.25 +/- 0.05cm
If I convert 8.25 to m how to I .. convert my uncertainty?

Your uncertainty shouldn't change with the units. .05 cm is .0005 m. After all there is no uncertainty introduced with the conversion.

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 '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}...
