In problem 12 on p. 663, you estimated the energy released in a bolt of lightning, based on the energy stored in the electric field
immediately before the lightning occurs. The assumption was that
the field would build up to a certain value, which is what is necessary
to ionize air. However, real-life measurements always seemed to
show electric fields strengths roughly 10 times smaller than those
required in that model. For a long time, it wasn’t clear whether the
field measurements were wrong, or the model was wrong. Research
carried out in 2003 seems to show that the model was wrong. It is
now believed that the final triggering of the bolt of lightning comes
from cosmic rays that enter the atmosphere and ionize some of the
air. If the field is 10 times smaller than the value assumed in problem
12, what effect does this have on the final result of problem 12?

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

Carbon is allowed to diffuse through a steel plate 15 mm thick. the concentrations of carbon at the two faces are 0.65 and 0.30 kg c/m^3 fe, which are maintained constant. if the preexponential and activation energy are 6.2 x 10-7 m2 /s and 80,000 j/mol, respectively, compute the temperature at which the diffusion flux is 1.43 x 10^-9 kg/m^2 -s.

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
