sorry, didn't realize - h is z (height)

PHYSICS
I used this one: p=p0*[T0/(T0+alpha*(h-h0))]^(g*M/(R*alpha))

PHYSICS
I found two types of formulas for such a problem - the first one is only for the case of isothermal atmosphere, the second one is for this case, in which the temperature is the function of the height - maybe that's why your solutions aren't correct

Physics
A curve of radius 59.9 m is banked so that a car of mass 1.4 Mg traveling with uniform speed 50 km/hr can round the curve without relying on friction to keep it from slipping on the surface. At what angle is the curve banked? The acceleration due to gravity is 9.8 m/s2 * I swe...

math
Proving Trigonometric Identities 1. sec^2x + csc^2x= (sec^2 x)(csc^2 x) 2. sin ^3 x / sin x - cos 3x / cos x = 2 3. 1- cos x/ sin x= sin x/ 1+ cos x 4. 2 sin x cos ^2 (x/2)- 1/x sin (2x) = sinx 5. cos 2 x + sin x/ 1- sin x= 1+ 2 sin x

What is the function of macronucleus and micronucleus in a paramecium?

biology
Why are multicellular protista( seaweed) not classified in the plant kingdom?

physics
using the formula vf^2=vo^2+ 2ad you can find out the answer. Because the stone is dropped the acceleration is -9.8m/s^2 and the vo=0m/s. The distance is aleady given to you. From here simply plug in the numbers and do the calculations to figure out vf. It should be around 11m/s
