what type of clothes do I need to wear to go deer hunting?
You are correct and you're brother is mistaken unfortunately. Any modifiers to a monster's attack or defense after Shield Sword has been played are applied to the NEW attack and defense. So, Reinforcements simply increases brother 2's new attack (original defense) by 500 points. Hope this helps ) -TZ
Conservation of Momentum. There is zero momentum in the system to start with, so there must be zero total at the end. With water shooting out the front of the hose in the positive direction, the hose must fly backwards in the negative direction to add up to zero momentum. This is the same reason that in shooting a bullet out of a gun you effectively shoot yourself as well (this is known as recoil and it tends to surprise first-time gun shooters who have watched too many unrealistic gun movies).
