Yes velocity is a vector that has both speed and direction. So if you are going 30 mph in one direction that may be positive, but if you are going in reverse that may be negative.
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
Impossible.
No.
Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.Frequency = Speed/Wavelength.Since the speed is not known, it is not possible to provide a more useful answer to the question.
In classical physics, negative speeds do not make sense as it implies going backward in space. In some contexts, negative speeds can be used in mathematical models or theoretical physics to represent certain relationships, but they do not have a physical interpretation as traveling at a negative speed.
No, in physics, speed and displacement are scalar quantities that represent magnitudes and cannot be negative. However, the direction of motion can be indicated by assigning a negative or positive sign to the speed or displacement value.
Speed is (distance covered in some time) / (time to cover the distance).Neither the distance covered in the time, nor the time duration, can be negative.If you'll say "Well what about moving backwards ?", then you have introduced the directionof motion into the discussion, and now you're talking about velocity, not speed. Velocity caneasily be negative, but speed can't.
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
yes, it is possible to have a negative decimal.

No, the speed of a particle cannot be negative. Speed is a scalar quantity that only considers the magnitude of the velocity, not its direction. Therefore, it is always positive or zero. In cases where the particle reverses its direction, the velocity is negative but the speed remains positive.
Yes it is possible...
retardation is nothing but the decrease in speed. so if the increase in speed can be taken as positive then for sure decrease in speed can be taken as negative acceleration.
Impossible.
No.
Radii are always positive. No, it is not possible to draw a circle with negative radius.
