The proton is not truly a point particle, but can be modeled as
a sphere of radius approx 1 fm. This is an approximation. Calculate
the probability that the electron in the ground state of hydrogen
will be found within 1.00000 fm of the center of the proton in the
following two ways. Talk about the differences or lack of
differences between the two results.
a.) Integrate the radial probability density over the
appropriate range of radii.
b.) Multiply the...

Write a C++ program to calculate the sphere volume and surface
area. Provided
that the sphere volume = and the sphere surface area = , where r is
the radius.
1. Read r from the user using cin statement.
2. Calculate the volume (Vol) and the surface area (Area) of a
sphere.
3. Print r, Vol, and Area in a suitable messages.

To a rough approximation, the Earth can be treated as a greybody
sphere with uniform temperature, absorptance ? = 0.70 and
emissivity ? = 0.61. The low absorptance is largely due to
reflection of the incoming sunlight by clouds and ice, while the
low emissivity is largely due to greenhouse gases in the
atmosphere.
a) Over timescales of decades, the total solar
irradiance at the Earth varies between about 1360.3 W/m2
and 1362.0 W/m2 . Using the greybody Earth
approximation,...
