I saw a demonstration of the magnetic nature of liquid dioxygen. Surely the gaseous form is also magnetic? So could Oxygen be somehow distilled from air with a strong enough magnet?

We all know that ducks go "quack", but do geese really "honk"? How would you render the noise of a goose to a small child, realistically?

So, I want a 15amp circuit breaker on the headlights of my vintage car (12 volt). I have two 7.5 amp circuit breakers. I could put one circuit breaker on each headlight, but what would happen if I wired the two circuit breakers together in parallel? Could I draw 15amps through the pair of them, or would they trip at 8amps?

Finally, and just out of interest, if you wired a 10amp breaker and aa 5 amp breaker together in parallel, when would they trip?

The equation is shown with letters, each letter stands for a number. Try to solve this problem:

(k*(r+w+m)/t*a*(z-d-b+v))*(v*b*d*z*m*r*k*w)=k

Just try to solve the value of k.

I thought that if you are adding interest to an amount continuously (every moment), it would definitely gain more than having the same amount being compounded only monthly or annually.
the equation for continuous compounding is S = Pe^(j-infinity*t)
S = future value
P = principal amount
e = natural log
j-infinity = force of interest (also denoted with delta)
t = time
