A tumour located at a depth of 10 cm is treated using a non-isocentic technique with a Co-60 machine, to a dose of 1.8 Gy, with a single 5 cm x 5 cm beam. Compute the maximum dose received anywhere in the patient's anatomy. Refer to the attached table for PDD data.

a) At what depth does the maximum dose occur?

b) Compute the dose at a depth of 5 cm along the beam axis

The rectangular block below has front-face dimensions of 10 cm by 4 cm, with a depth of 3 cm.(Figure 1) You will be asked to treat this object as an electrical resistor. Rank the block based on its electrical resistance along the three illustrated coordinate directions (x, y, and z). Rank from largest to smallest. To rank items as equivalent, overlap them. PART B: If all of the dimensions of the block double (to become 20 cm wide, 8 cm...

In general, the index of refraction may vary with depth; this can be treated by considering the medium as a sequence of thin layers. a) Starting from Snell’s law obtain a relation between dθ/dz and dn/dz . [Hint: Choose a thin layer going from z to z dz + and write n andθ in terms of z and z dz + , then apply Snell’s law to either side of the layer. ] b) Apply this result to an electromagnetic...

A converging lens (f1 = 24.0 cm) is located 56.0 cm to the left of a diverging lens (f2 = -28.0 cm). An object is placed to the left of the converging lens, and the final image produced by the two-lens combination lies 20.4 cm to the left of the diverging lens. How far is the object from the converging lens? do1 =
