Usually false because the dripping, carbonate-rich water spreads out on impact, whereas it is concentrated in the drip... but Nature doesn't work to standards when decorating caves!
Usually yes: its formative calcite solution is concentrated on the tip of a stalactite but spreads out on impact with the cave floor or the top of the stalagmite.
True.
True. Stalactites are mineral formations that hang from the ceiling of a cavern or cave, formed by dripping water containing minerals that slowly build up over time.
1 millimeter every 10 years >.. That may be true for the cave or region giving that value, but the growth rate varies greatly from place to place according to a range of variables. It can be more rapid than that but is often far slower.
As water goes through ground, it will to a certain extent dissolve some minerals. When water later drips down inside a cave, the water can actually deposit a little bit of the minerals it is carrying. This results in Stalactites from roof and Stalagmites at ground. It is true.
It is not true.
False
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
False. It is software.
True
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
true!
