2.wegener formed a theory of continental drift in 1912. what prevented research of the ocean floor paleomagnetism and earthquakes at that time?

3. if many different observations can all be explained by the same theory,does that make it true?does it make it more likley.

3. how certain do you feel that plate tectonic theary is correct what evidence would you use to support yor opinion

One mole of nitrogen gas confined within a cylinder by a piston is heated from 0°C to 883°C at 1.00 atm.

Calculate the work of expansion of the gas in joules (1 J = 9.87 10-3 atm·L). Assume all the energy is used to do work.

What would be the temperature change if the gas were heated with the same amount of energy in a container of fixed volume? (Assume the specific heat capacity of N2 is 1.00 J/g·K.)

CaCO3 + 2HCL = CO2 + CaCl2 + H2O

I think it is is a redox reaction because the CO3 becomes a CO2 .... is this correct ?

At work today, all five of us were left-handed. We thought that was odd and wondered the odds of that happening. Assuming the chances of one person left handed are 10%, I said the probability was 3.125%: Chances of selecting one person out five from a large population being left handed 50%, two 25% three 12.5% etc. Another person said it was much smaller .001%: .1^5. Who, if anyone, is correct?

It was faked, at least portions of it- there is no question about that. I am not necessarily saying we did not actually land on the moon; just saying the photographs and film were fakes.
Had the astronauts been on the moon, they could have bounded upwards 10 feet with each step, everything they did was filmed in slow motion, and nothing they did (movement- wise)couldn't have been filmed here on Earth. I won't get into the other factors of dust, lighting, wind, radiation effect on film etc., because it is apparent the pictures were indeed faked.
But, as I alluded to earlier, just because the pictures are obviously fakes, that doesn't mean that man did not land on the moon. Perhaps we did land on the moon but what we found was so ??? that the government had to cover it up with the fake images....
