It depends on which reference frame you want to use. According to the reference frame connected to the crane, it will not change. According to the reference frame associated with the ground the center of gravity will of course change.
Yes. The angle is the direction of the vector, so if the angle changes, the direction changes.
The angle of reflection is equal to the angle of incidence. When the angle of incidence changes, the angle of reflection will also change accordingly, maintaining the law of reflection.
Changing the angle of an object's motion will affect both the horizontal and vertical components of its velocity. For example, if you increase the angle of launch for a projectile, it will have a greater vertical component and a shorter horizontal component. This will result in a change in the overall velocity vector of the object.
The angle of reflection is equal to the angle of incidence when light hits a flat and smooth surface. If the angle of incidence changes, the angle of reflection will also change proportionally to maintain this equality in accordance with the law of reflection.

Yes. You can consider a vector of being made up of a magnitude (size) and a direction. If any of the two changes, it is no longer the same vector. Alternately, you can also consider a vector (in two dimensions, for simplicity) as being made up of an x-component and a y-component. It is not possible to change the angle without changing at least one of the two components.
The CP is the average of all the pressures acting on the aerofoil and as such it will change in magnitude and position as the pressure patterns around the aerofoil changes. The biggest change will be because of changes in angle of attack. The AC is a point on the aerofoil that does not move as you change angle of attack. If you imagine a pivot point on the trailing edge then the aerodynamic forces would make the aerofoil pivot leading edge up about that point. If you now imagine the pivot point at the leading edge then the aerodynamic forces will make the areofoil pivot trailing edge up about that point. If that is so, then there must be a point somewhere between the leading edge and the trailing edge where there will be no change in the pitching moment of the aerofoil as the pressure pattern on the aerofoil changes. That is the AC and it is found at about 25% of the chord. The AC is defined as a point on the chord line that : (1) does not move as angle of attack is changed (2) the pitching moment of a wing is always constant about it
As the angle of attack increases, the center of pressure on a wing moves towards the leading edge of the wing. This shift in the center of pressure is due to changes in the distribution of lift forces acting on the wing at different angles of attack. It's important for pilots to understand these changes in order to maintain control and stability during flight.
On Earth, the greatest changes in the seasons are found near the poles. This is caused by the tilt of the Earth's axis that changes the angle of the Sun's rays from season to season. Near the equator, there is little change in the angle of the rays, and so little change in the seasons.
