AI Thread Summary
A uniformly charged conducting plate with infinite extent has a surface charge density denoted as surf. A Gaussian surface, specifically a cylindrical pillbox, is used to analyze the electric field near the surface of the plate. The integral E * dA is applied to calculate the electric field, focusing on the contributions from the charged plate. The discussion emphasizes the importance of understanding the electric field behavior in relation to the Gaussian surface configuration. This analysis is crucial for deriving the electric field strength in the vicinity of charged conductors.

1. Consider a uniformly charged conducting
plate with an infinite extent, where the sur-
face charge density is surf . We introduce a
Gaussian surface as a cylindrical pillbox of ra-
dius a, half-way submerged into the surface.
The figure below shows a chunk of the infinite
plate and the pillbox configuration.

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}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
