I need the solution for 1 dimensional wave equation. Please note that, when you assume any constant for deriving the solution,the actual value of the constant must also be derived. I would be grateful if anyone helped me.

Ok creo's and evo's we all know about poluxy and we know what it shows giant man and dino tracks

creos claim it wasa giant man as the atmosphere would support giant lizards, beavers, rhinos which have all been found, so any men around would have been giants too


but lets not babble.

Why do evolutionists simply test this rock and some of the footprints and give us a date?

Why do they never test creo evidence

Just radiodate using some of your methods and tell us what you get

there must be evo scientists with dating techniques in their labs from america repsonding to this question

so why not test the footprints and give us a date for them

that would **** up one group of people

does anyone know why these footprints have not been tested

will someone please test those footprints, using any method you like

at the same time can you also test the mayan claypots, which show the mayans riding on the backs of dinosaurs too
thanks

lets test these things and get an answer for everybody

w2=-225
w² = -225
w² + 225 = 0
w² + 15² = 0
w² - (15i)² = 0
(w+15i)(w-15i) = 0
w = {-15i, 15i}

Recently I've seen two or three buzzards overhead, sometimes calling. I know that this is the adults way to get the young to leave the family group, but also pigeon feathers have appeared in the garden, plucked out. They are haphazard, not in a circle like a sparrowhawk. Do buzzards take pigeons? & if so, do they take them on the wing?

i havent got the slightest idea how to answer this:

A smoke detector operates using alpha particles from a radioactive Am 241 source.
A typical detector contains 0.2 milligrams of Am 241. the detector can only function if the mass of Am 241 exceeds 0.15 milligrams. Assuming that the lifetime of Am 241 is 624 years, calculate the operational time of the detector.

also does this mean its halflife is 624 / 2 = 312 years?
i've never seen any question like this before

does anyone know a better place to ask higher level science questions? I don't like plaguing my profs w/ questions, but often the hard questions I ask, or that other ppl ask, don't get good answers here.

An insecticide is known to contain C, H, and Cl. Reactions were carried out on a 1.000g sample of the compound that converted all of its chlorine to chloride ion dissolved in water. The aqueous solution was subsequently treated with an excess of AgNo3 solution and the AgCl precipitated was collected and weighed. Its mass was 2.022g of AgCl.
What is the equation of the rxn?
How many moles of Cl (Cl-) were in the AgCl sample?

A soluble iodide was dissolved in water. Then an excess of AgNO3 was added to completely precipitate out all of the iodide ion as AgI. 1.545g of soluble iodide yielded 2.185g of AgI
What is the equation of the rxn?
How many mol of I (I-) are in the original soluble iodide sample?

Kennedy announced we were going to the moon in the 60s and we took 8 years to do it. Bush announced in 2004 that we'd be back to the moon by 2020. Why does it take so long? Russians and Chinese have announced they will do it by 2025.

So the question is WHY DOES WE TAKE SO LONG to go back??

a. locate the exact or approximate intercepts
b. identify any axis of symmetry
c. determine the curves behavior at positive and negative infinity
d. use the first and second derivative to locate turning points

3. find the area common to r=1+cos@ and r=3^(1/2) sin@

4. specify the points of intersection of rcos@=1 and r=4cos@

5. tnagents are drawn to the ellipse x^2/a^2 + y^2/b^2 =1 and the
circle x^2 + y^2 = a^2 at points having the same abscissa. prove that

A ladder 5.7m long rests against a vertical wall at angle f 34*(degrees)02' with the vertical wall. How far is the foot of the ladder from the wall? If the distance of the foot of the ladder from the wall is reduced to half its original distance, at what angle should the ladder be inclined to the wall?
