yes they have the same speed
Assuming both balls have the same mass and are released at the same time, they would reach the bottom of the incline at the same speed regardless of their size. This is because in the absence of air resistance, all objects fall at the same rate of acceleration due to gravity.
The momentum stays the same.
All electromagnetic waves travel at the speed of light in a vacuum and can be characterized by their wavelength and frequency.
No, light does not always travel at the same speed in all mediums. Its speed can vary depending on the medium it is passing through.
They'll both reach the top of their arcs, turn around, and begin to fall at the same time, fall with the same acceleration, and hit the ground at the same time with the same speed.
All four balls would have the same kinetic energy since kinetic energy is determined by both the mass and velocity of the object. If all four balls have the same mass and velocity, their kinetic energy would be equal.
The scientist would set up an incline plane with the same angle for both balls and release them from the same height at the same time. If the balls reach the bottom of the incline plane at the same time, it suggests they roll down at the same speed. Any differences in speed could indicate that factors such as mass or shape affect their rolling speeds.

they all have the same speed
The momentum stays the same.

Depends on the brand . Not all cheese balls are the same.
The speed of all sounds is the same in the same medium.
All electromagnetic waves travel at the speed of light in a vacuum and can be characterized by their wavelength and frequency.
All types of electromagnetic waves have the same speed through a specific medium (the same speed in a vacuum, the same speed through air, the same speed through glass, etc.), but they all travel slower through denser media.
the balls decrease in speed
