Proofs Do Problems 1-3 in flowchart proof format   Proofs do not require bulletpoint explanations.

An electron is traveling along the positive x-direction in the presence of a magnetic field pointing in the -z direction (into the page). The initial deflection of the electron is in the 

Researchers are working on techniques to kill cancer cells by targeting them with ultrahigh-energy pulses of light that last for an extremely short time (a few nanoseconds). These short pulses scramble the interior of a cell without causing it to explode, as long pulses would do. We can model a typical such cell as a disk 5.0   in diameter, with the pulse lasting for 4.0 ns with an average power of 2.0 x 1012 W. Assume that the energy is spread uniformly over the faces of 100 cells for each pulse. Calculate the maximum magnetic field in kilo-Tesla within each pulse. Express your answer in kilo-Tesla. Two significant digits. 

An alpha particle is moving at a speed of 5.0 × 105 m/s in a direction perpendicular to a uniform magnetic field of strength 0.040 T. The charge on an alpha particle is 3.2 × 10-19 C and its mass is 6.6 × 10-27 kg. What is the radius of the path (in meters) of the alpha particle to two significant digits?  

A long solenoid of radius 3.0 cm has 2000 turns per meter. If the solenoid produces a magnetic field of 0.220 T through the center, calculate the current through the windings. Two significant digits.

What legislation did Ed Penny say he has worked on a lot and is the largest funder of private-land conservation?

In assessing a newborn male, the urethral meatus is located on the ventral side of the penis. What is the likely diagnosis?

Purulent, cloudy or yellow discharge from the penis is suggestive of 

A buyer has inventory with the following figures: Total Merchandise Handled at Cost = $65,600 Total Merchandise Handled at Retail = $150,000   Find: COST PERCENT on total merchandise handled
