Determine the possible effects on the water level - Physics Forums
2012年7月2日 · A small solid sphere of mass M0, of radius R0, and of uniform density ρ0 is placed in a large bowl containing water. It floats and the level of the water in the dish is L. Given the information below, determine the possible effects on the water level L, (R-Rises, F-Falls, U-Unchanged), when that...
Proof using pumping lemma that - Mathematics Stack Exchange
2016年1月27日 · A much easier proof, essentially using the pumping lemma, is to assume 0m1n 0 m 1 n is regular ( m ≠ n m ≠ n throughout ), then there exist a DFA that ends in an final state if and only if the input is 0m1n 0 m 1 n. Now swap the role of final state and non-final state, you get a state machine that stop if and only if the input is 0m1m 0 m 1 m, but by pumping lemma we …

Is the language $L = \\{0^m1^n: m \\neq n - 1 \\}$ context free?
Consider the language: L = {0m1n: m ≠ n − 1} L = {0 m 1 n: m ≠ n − 1} where m, n ≥ 0 m, n ≥ 0 I tried for hours and hours but couldn't find its context free grammar. I was stuck with a rule which can check on the condition m ≠ n − 1 m ≠ n − 1. Would anyone can help me out? Thanks in …

How to prove proposition $2.2.14$ in Tao Analysis $I$?
Proposition 2.2.14 2.2.14 (Strong principle of induction). Let m0 m 0 be a natural number, and let P(m) P (m) be a property pertaining to an arbitrary natural number m m. Suppose that for each m ≥ m0 m ≥ m 0, we have the following implication: if P(m′) P (m ′) is true for all natural numbers m0 ≤ m′ <m m 0 ≤ m ′ <m, then P(m) P (m) is also true. (In particular, this means that ...
