And slightly more efficient than in line skates which is slightly more efficient than ice skating, it turns out.
A professor once asked on a test "How can you determine the height of a building using a barometer." There are at least 8 different ways to do this. Which ones can you think of?
Yep. I can still remember that to explain this was the extra points question on a high school physics final. Got it! I remember being shocked by that LOL!
I had to use Google to find out about Schumann Resonances fit your question. https://en.wikipedia.org/wiki/Schumann_resonances
And the fundamental frequency is 7.5 Hz - right about the center frequency for the brain What an amazing coincidence! Esp considering that our brains have been bathed in this EM field for as long as we've been evolving. You could say that Schumann resonance is the electromagnetic heartbeat of the planet.
So far I can only come up with these... You can compare the barometric pressure at the top and bottom of the building, and look up the elevation change corresponding to that value. You could compare the atmospheric pressure at ground level to a column [tube] of a different gas, as tall as the building You could use a column [tube] of liquid with a known density, mounted on the building and just as tall, You could measure the barometer and see how many barometer lengths the building is tall. You can drop the barometer from the top and see how long it takes to hit the ground. You can drop it from the top and measure it's maximum velocity just before it hits the ground.
You can also use the barometer as a pendulum. But my favorite is to find the building superintendent and say "I will give you this fine barometer if you tell me how tall the building is." Another is to measure the length of the shadow of the building and the shadow of the barometer and compute the similar triangles.
Question 15: If ASCII is [incorrectly] called American Standard Code 2, what is sometimes euphemistically considered to be American Standard Code 1?
I had to think about that one for a moment. Then I realized there are two ways. The period of a pendulum T = 2 x pi x Square root [L/G]. L is the length of the string and G is the acceleration due to gravity In one, L is the height of the building and we get T from that. In the other, we see how gravity varies between the top and bottom of the building.
Question 16: When the first radio telescope was turned on, they thought they had a problem with bird poop on the antenna causing a noisy signal. But it turned out to be something else. What was it. Correction. It was not the first, not even close. It was intended to map the Milky Way.
No it wasn't background radiation, deffo bird poop. I used to be confused by what was meant by background radiation believing it was radiation similar to light. Then I saw the "light" when I saw a description of imagining a huge explosion in a small container giving rise to an average temperature in that container. Now imagine that the container begins to expand, that average energy will begin to decrease giving rise to our current average temperature of our universe of 2.7K from which one can guesstimate the size of the universe and the energy 'created' by the "explosion"
Yep, the Cosmic Background Radiation. They thought the fingerprint of the Big Bang was bird poop. True poetry! However, the CMB radiation is the same thing as light, just at a lower frequency. https://en.wikipedia.org/wiki/Thermal_radiation
Ima guess that certain cups have enough air resistance to breifly overcome gravity. Or maybe it has to do with the rotation of the earth providing a gyro effect on the cup?
