g Consider a dielectric sphere of radius Rand permittivity 1moved into a region of space containing a dielectric of permittivity 2and originally threaded by a constant electric field E0. Find the new electric field everywhere after the sphere is moved into place. To make it clear, the same problem can be stated as: Given a sphere of radius Rand permittivity 1submerged into a medium with permittivity 2and a field which, far from the sphere, is uniform with magnitude E0, find the field everywhere in space.

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?

When using the scientist method, which step comes last?
