1 Larmor radius and gyration frequency (10 P) Calculate the Larmor radius and the gyration frequency (4 P) for:

1. An electron in the Earth’s ionosphere at 300 km altitude, where the magnetic flux density is B ≈ 0.5 · 10−4 T, considering that the electron moves at the thermal velocity (p kT /m) with T = 1000 K. (1 P)

2. An oxygen ion O+ in the Earth’s ionosphere for the same conditions as above. Is there a difference in Larmor radius and gyration frequency between the ion and the electron? Explain. (3 P)

3. A 3.5 MeV He++ ash particle in an DT fusion reactor. Use the kinetic energy of the particle to calculate the velocity, assuming that v|| is negligible.

Calculate the wave propagation speed for a 100-?m-thick blood vessel with a radius of 10 mm. This blood vessel has a pressure of 85 mmHg and a Young’s modulus of 12.5 kPa. Under disease conditions, the vascular wall can stiffen so that the Young’s modulus approaches 30 kPa. Calculate the change in the wave speed under these conditions. What blood vessel property is likely to change in response to the increase in stiffness and why?
