Imagine a person is moving at the equator in the direction opposite of the Earth's spin. How long would it take them to stop the rotation of the Earth?
Assume:
the person's "weight" = 90.718 kg,
they person's speed = 1m/s,
The Earth's "weight" = 5.972*10^24 kg,
the angular velocity of the...
I can say that the reason why rain drops will tend to follow the trails of other drops is because of the property known as cohesion. As water molecules come close to one another the hydrogen bonds attract the molecules together.
You can use the equation for work: W=F * D where D is the distance.
Substitute for D: D = circumference = pi * d, where d is the 0.36 meter diameter. Now the rest of the calculations should be self explanatory.
Apparently, according to WebMD.com, the average person only absorbs 10% of ingested iron, while people with hemochromatosis can absorb up to 30%, which can cause iron poisoning.
I have poor diverse food intake and wake up groggy even after more than 8 hours of sleep. I can sleep for 12 hours...
I have seen that the recommended daily intake of iron for adults is 45 mg/day. I've seen even lower estimates. These iron pills that I bought contain 50 mg of iron and give 278% of your daily value intake. The instructions say take two tablets daily.
Isn't this a bit extreme or am I not...
This seems like an awesome idea because it looks like a particle accelerator:

I assume that those are just standard neodymium magnetic balls.
Nascar races tend to use left turns. Why is this?
Well my reasoning behind this would be that when an object (like a wheel) rotates counter-clockwise, it generates torque in a direction perpendicular to its rotational plane. This torque points to the left, therefore left turns are easier than...
Thank you for your insight.
Use all of them, analyze all of them. I think that the smaller the time interval, the more unpredictable and chaotic the predictions become. The monthly and yearly graphs may be more reliable.
Interestingly enough, if you infinitely integrate a position function, the result makes no physical sense what so ever, only the derivation does. The derivation converts the units that CompuChip mentioned.
If you integrated the seemingly random "curve" of a stock graph (http://www.stockpickssystem.com/wp-content/uploads/2011/03/1929-stock-market-crash-stock-chart-djia.gif), what physical value would you get out of it or does this not make any sense?
On the contrary, if you took the derivative at...
It's easy to have computers express everything in numbers. Because with binary states, 0's and 1's, you can string together these two simple states in order to create any number you want, you just have to convert it to our base 10 system.
"Complexity arises from ordered simplicity." That is to...
I wanted to figure out the temperature(t2) of any object based on things such as its specific heat capacity, re-entry speed, etc.
Work: W = Fy
Force by Air: FD = 1/2pv2CDA
Energy-temperature relationship: Q = mc(t2 - t1)
Setting things equal & solving for t2 gives:
t2 = (1/2pv2CDAy+mct1) /...
