It has been proven definitively that there is a time dilation effect at different altitudes. It is a well established principle of general relativity. What, then, is the time dilation at the center of the Earth?

It seems too easy...or I'm just not thinking at all...please guide me in the right direction...?

Given f(x) = abs(sinx) for -3.14 < x < 3.14 and g(x) = x^2 for all real x.

Let H(x) = g(f(x)). Write an expression for H(x).

Isn't this how you would normally work it out...?

y = g(f(x))
y = g(abs(sinx))
y = (abs(sin(x)))^2 = H(x).

Please help!

My mom is a resident of Hawaii, and was trapped on a low elevation island when the earthquake occured last sunday.

Considering Hawaii is not on a fault line, but rather the center of a moving teutonic plate and it is known that continental lift usually occurs at a fault line and a tsunami is the result of this dramatic upshift when it occurs underwater. Of course, any earthquake can cause massive landslides which can trigger large waves.

My assumption is that there is a much higer risk of a tsunami traveling to Hawaii.

Consider two flasks that are connected by a valve.

One flask has a volume of 2.00L and contains H2 at a pressure of 200.0 Torr. The other flask has a volume of 3.00L and contains N2 at an unknown pressure. If the total pressure in the flasks is 260.0 Torr after the valve is opened, what was the initial pressure of the N2 in the 3.00L flask?
