The highest waterfall in the world is the Salto Angel Falls in
Venezuela. Its longest fall has a height of 807 meters. If water at
the top of the falls is at rest and at 15°C, what is the maximum
temperature of the water at the bottom of the falls? Assume all the
kinetic energy of the water as it reaches the bottom goes into
raising its temperature. The specific heat capacity for water is
4186 J/kg°C.

Q) What is the kinetic energy, in joules, of a molecule of oxygen moving at a speed of 255 m/s(use the appropriate prefix to avoid exponential notation) a) The equation for kinetic energy is ½mv2, and is in units of joules. What are the component units for joules in terms of mass and velocity? kg m^2/s^2 b) From the previous part, we know that the mass needs to be in units of kg. What is the mass of an oxygen...

The oxygen molecule, O2, has a total mass of 5.30×10-26 kg and a rotational inertia of 1.94×10-46kg-m2 about an axis perpendicular to the center of the line joining the atoms. Suppose that such a molecule in a gas has a speed of 1.48×102m/s and that its rotational kinetic energy is two-thirds (2/3) of its translational kinetic energy. Find its angular velocity.

Consider the diatomic oxygen molecule, O_2, which is rotating in the xy plane about the z axis passing through its center, perpendicular to its length. At room temperature, the "average" separation between the two oxygen atoms is 1.21 times 10^-10 m (the atoms are treated as point masses, each with 2.66 times 10^-26 kg.) (a) Calculate the moment of inertia of the molecule about the z-axis. (b) If the angular velocity of the molecule about the z axis is 2.0...
