Any change in the speed or direction of motion is called "acceleration". You'll hear "deceleration" used for slowing down but that's not technically correct.
The unit is light years or Ly
Intrapulmonary pressure is the pressure within the lungs
The magnetic flux through an area A is given by

where
B is the magnitude of the magnetic field
A is the area

is the angle between the direction of B and the perpendicular to the surface A.
In our problem, the area lies in the x-y plane, while B is in the z direction, this means that B and the perpendicular to A are parallel, so

and

, so we can rewrite the formula as

We can calculate the area starting from the radius:

And then using the intensity of the magnetic field given by the problem,

, we find the magnetic flux:
