Second level activities are activities that have to do with manufacturing.
A natural disturbance includes a lava flow, earthquake, or a forest fire. But human forces can also be disturbances, such as farms.
Physics.
It is physics.
The force that includes both electricity and magnetism is called the electromagnetic force.
The photon is responsible for mediating the electromagnetic force. This includes both electricity and magnetism (both of which are manifestations of the electromagnetic force.) Interestingly, the photon is also the particle responsible for light, which is an electromagnetic wave.
A contact force, including friction, springs, pushes, pulls, requires the two objects to be in contact for the force to exist. On the other hand, non-contact forces do not require contact; the two objects are separated by space, and yet the force exists. This includes gravity, electricity, magnetism, and nuclear forces.
Physics
It means the branch of science concerned with the nature and properties of matter and energy. The subject matter of physics includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms.

Yes. In physics, the types of friction include: static friction, sliding friction, rolling friction, and fluid friction. Water has fluid friction. This is considerably less than static friction, but it's there. Fluid friction also includes other liquids and air (things that flow).

The materials that, in general, change sliding friction to fluid friction are called lubricants. This class of materials includes oil, grease and the like.
