Suppose a meteor of mass 3.30 1013 kg is moving at 32.0 km/s relative to the center of the Earth and strikes the Earth. Suppose the meteor creates the maximum possible decrease in the angular speed of the Earth by moving toward the west and striking a point on the equator tang...
The density of the Earth, at any distance r from its center, is approximately (14.2-11.6(r/R)*10^3) Kg/m^3, where R is the radius of the Earth. Show that this density leads to a moment of inertia I = 0.330MR2 about an axis through the center, where M is the mass of the Earth. ...
A monoprotic acid with a Ka of 2.92 × 10-5 has a partition coefficient of 4.2 (favoring octanol) when distributed between water and octanol. Find the formal concentration of the acid in each phase when 100 mL of 0.10 M aqueous acid is extracted with 31 mL of octanol at (...
I am a number between 50 and 60. One of my factors is 28. What number am I?
How would you derive n(E)= E^2/((e^E/T) - 1) a) Evaluate dn/dE at fixed T. Leave answer in symbolic forms of E and T. b) dn/dT at fixed E.
a 210 Newton force is applied to a piston, the force produced is 320 kPa of pressure, what's the area of the piston?
Oh! I understand now, thanks so much to both :)
Sorry, how did you get that? :(
