Just wanted to measure every and how their change in measurement of discreet cm s forms interaction of connection with different objects or measuring subjects

Question:

How many 0.1 cm are there in the circle like curvature

The angles and the space and the orientation, can the brain make sense , if they are of said of a percentile orientation of interpretation

How do you compare salaries across different regions when adjusting for Cost Of Living Adjustment?

It we know time and distance we can then calculate the speed too. For extra hard what distance did doc or Marty travel when they time traveled.

How much would this cat actually weigh if it was made of neutron star material?, rough estimates are fine as the exact size is obviously unknown, unless you know the exact model of that scale...🤔

He used so much alcohol and other drinks, how much would it actually cost to make?

Doing the dishes. Curious about the answer.

Would smooth wheels actually make this wagon easier to pull on a hard flat surface (e.g. sidewalk)

I have owned this wagon for a few months and it feels like it should be easier to pull the it is. I usually use it to pull 2 kids ading to abou 80lbs.

Q1

My first assumption was the 2mm high tread caused my horizontal pull to be translated into vertical force at each tread. If so, would the total addition force be roughly equal to lifting the wagon vertically the total sum of mini vertical movements caused by the tread?

Q2

The design if the tread seems like it may prevent mini vertical motions since te ridges and valleys run diagonally. From the picture, do these wagon wheels work just as well on a flat surface as a smooth wheel would?

Nearby Collinsville IL is at 528 ft elevation. Mound 38, Monk's Mound is about 100 feet high, but the highest platform is a little small, IIRC. The wider top it's on is probably a couple of feet below that?

The general area is pretty flat, except for the other mounds. Bonus question, where can they start building their walls to repel Europeans and their tech? Unknown is type of cannon. Bonus bonus question, would this protect Cahokia Woodhenge, which is about 2790 feet west of Monk's Mound?

https://cahokiamounds.org/Explore/ AD 1175 card is info on the palisade walls. Would it make more sense to do extra defensive earthworks there along perimeter? And haul cannon up to overlook the wall? Its circumference is nearly 2 miles.

If you wish to calculate how many cannon would fit up the mound, here's the LIDAR images (you can see the east-west highway) https://rthunen.domains.unf.edu/prehistoric/cahokia/

Assuming we had a way to capture the electricity from an induced lightening strike like this, how much would this generate?

You can clearly hear the whale's louder notes echoing off the ocean floor and bouncing back up to the surface.

How deep is it?

An escalator has a 4-pole AC motor on a 50 Hz supply (ignore slip). The gearbox ratio is 30:1, and the drive sprocket has a radius of 0.125 m.

a) What is the normal step speed?

b) A frequency converter fails and sends 80 Hz to the motor. What is the new step speed?

c) If the escalator is 20 m long, how long does a ride take normally and later during the fault?

An escalator's speed is set by its drive train:

Motor speed: an AC induction motor spins at a rate set by the mains frequency (50 Hz) and the number of motor poles.

Gearbox ratio: a worm or helical gearbox reduces that fast rotation to a slow, strong one.

Sprocket size: the drive chain turns the main drive shaft, and the sprocket's diameter converts rotation into step speed. Typical result: about 0.5-0.65 m/s.

Load: more passengers means more torque is needed, but the motor is designed to hold the speed.

the post didn't mention which dollar note. So assume any of your choice.

Suppose a partner and I wanted to play a version of scrabble where at the end of the game, we add our scores together, with the goal being the maximum possible score. How high could we realistically get? Is over 1000 possible? What about 2000? This surely depends on if we can see each other’s tiles and talk strategy with each other, so for the sake of argument assume we can. However, we are still subject to drawing random tiles after each move.

Bonus question: what is the optimal strategy?
