How Do You Calculate Pressure from Force and Area?

AI Thread Summary
To calculate pressure, use the formula P = F/A, where F is the force and A is the area. In this case, a 2 N force is applied over an area of 0.02 cm², which must be converted to standard units of m². The correct conversion shows that 0.02 cm² equals 0.000002 m², not 0.0002 m². This conversion error leads to incorrect pressure calculations. Accurate calculations are essential for determining the correct pressure in pascals (Pa).

.02 cm^2 (1m^2/100cm^2)=0.0002m^2.

No.

1 m^2 = (100 cm)^2 = 10,000 cm^2

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 'Struggle to understand the concept of the 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...
