Question: In Fig. the solid line shows a simplified version of the potential energy of an electron in an argon atom. The dashed line shows the total energy of a particular electron.
a. Is this electron bound in the argon atom? How do you know?
b. What is the electron's kinetic energy when it is at 0.05nm?
c. What is the de Broglie wavelength of the electron when it is 0.25nm from the origin?
d. What is the electron's de Broglie wavelength when it is at the center of the atom?
A blue spruce pine tree has the shape of a triangle which is 15 cm off the ground. The triangle has a maximum diameter of 6 m and is 10 m tall. Estimate the drag on the tree if it is exposed to a 25 m=s wind. Use CD ¼ 0.4 in your calculations.
