On a clear day at a certain location, a 119-v/m vertical electric field exists near the earth's surface. at the same place, the earth's magnetic field has a magnitude of 5.050 10-5 t.
(a) compute the energy density of the electric field. nj/m3
(b) compute the energy density of the magnetic field. µj/m3

If a balloon is taken outside on a very cold day, what will occur?

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
