The primary energy used to make cardboard is mechanical and thermal energy. Mechanical energy is used in the pulping process to break down wood fibers, while thermal energy is commonly used in the drying phase to remove moisture from the cardboard.
Ordinary cardboard is a type of paper, and is almost always opaque (visible light does not pass through it). It is possible to make it thin enough to make it translucent, especially in bright sunlight. If it were transparent (see-through) then it would not be called "cardboard" any more.
No, cardboard is not magnetic. Cardboard is typically made from paper fibers that do not contain magnetic properties.
If light strikes cardboard, the cardboard will absorb some of the light and reflect the rest. The color and thickness of the cardboard will affect how much light is absorbed or reflected.
According to Newton's Law of Inertia, the coin on the cardboard would tend to stay at rest when the cardboard is pulled slowly due to its inertia. As you pull the cardboard, the coin will initially stay in place relative to the glass of water due to its inertia. However, when the force increases or the cardboard is pulled quickly, the coin will slide off the cardboard due to the force exerted on it.

Some cardboard and paper are recycled to make new cardboard, but the primary raw material for cardboard is wood (celulose).
You can make cardboard more durable by adding layers, using thicker cardboard, or applying a protective coating like varnish or sealant.
A bin can be made out of a cardboard box without doing anything at all to it. However, if the cardboard is in pieces, it can be glued together with wood glue to make a bin.
