Yes according to most theories the velocity of light in a vacuum is constant. (In water and glass it is slower!)
An object moving in a straight line at a speed of 50 km/h with a constant velocity of 50 km/h in the same direction is an example of constant speed and constant velocity.
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
No, an object cannot have constant velocity and variable speed. Velocity is a vector quantity that includes both speed and direction. If the object's velocity is constant, then its speed must also be constant.
constant slope. really anything will work as long as it stays the same. so if your line is straight then you have a constant velocity. :)
Yes, it is. Trajectory also depends of direction of acceleration, not only it's magnitude. When you consider circular orbit, the agnitude of centripetal acceleration is constant, but the vector directions changes every moment to point constantly at the center.

Yes. Gamma Rays are photons (like visible light, just at another part of the electromagnetic spectrum). They travel with constant velocity at the speed of light (only in a vacuum). Although the original speed of the gamma ray varies.

Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
absolutely. The most important one in my bias opinion.
Yes, all xrays travel at the speed of light.
its frequency remains constant but velocity changes.

If your velocity is constant, then your acceleration is zero.
