0. "Constant speed" means it is not accelerating.
frequency = speed of wave / wavelength so if speed is constant then frequency varies inversely with wavelength
The product of its wavelength multiplied by its frequency is always equal to its speed. I think that's true even if the speed is not constant.
It is a measurment of speed, and means that if the speed remains constant the object will travel 120 kilometers in one hour.
In order to calculate how many minutes it would take someone to travel 5 kilometers you need to know the speed the person is traveling at. For example if the person is traveling at a speed of 60 kilometers an hour it would take them 5 minutes to travel 5 kilometers.
You can be accelerating and traveling at a constant speed if you change directions.
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.

0. "Constant speed" means it is not accelerating.
Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)
It has no acceleration. The definition of acceleration is the change in velocity over time, so if it is traveling at a constant speed, it has no acceleration. Also, the speed of light is a constant, which means it does not change.
When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
If your acceleration is zero, then yes, you are traveling at a constant speed. The path does not matter. Acceleration measures the change in velocity, so an acceleration of zero means that there is zero change in velocity and therefore the speed is constant.
The question is inherantly flawed. A car traveling at a constant speed cannot accelerate, if it could it's speed would not be constant. "Constant speed" means that speed is not increasing or decreasing but remain consistent over time. For example, if you cover 10 feet during each second, your speed is constant. "Constant velocity" implies constant speed, but it has an additional constraint: you can't change your direction. If you travel constantly at 10 feet per second in a straight line, then your speed is constant and your velocity is constant. But if you travel constantly at 10 feet per second in a wiggly line (or a circle, or anything not straight), then your speed is constant but your velocity is NOT constant. If you travel at a constant speed but change direction, velocity is changed. Or if you travel in the same direction but change the speed, velocity is changed. Average speed is is easier: distance/time So, your question should read: Why can a car traveling at an average speed accelerate, but a car traveling at constant speed cannot? Or Why am I asking the wrong questions?
Positive velocity will move you 200 miles east in 4 hours traveling at a constant speed.
Positive velocity will move you 200 miles east in 4 hours traveling at a constant speed.
No. Circular motion can have constant speed but varying velocity. Constant speed means constant speed in any direction, like a car on cruise control turning a corner. Constant velocity means constant speed in a straight line. If the direction changes, that's considered a change in velocity.
