Noo!
because it is a number
and distance that is a scalar quantity so it can not be negative and it have no direction also
Mass is a scalar quantity. Scalar quantities are those characteristics of matter that can be measured with a scale, while vector quantities are those that involve direction as well as quantity.
can a magnitude of a vector has negative value?
Velocity is a vector quantity that includes both magnitude (speed) and direction. Thus, velocity can be zero if there is no motion, but speed is the magnitude of velocity and cannot be negative. Speed is always a positive scalar quantity, so it cannot be zero if there is any motion at all.
Vector is NOT a scalar. The two (vector and scalar) are different things. A vector is a quantity (measurement) in which a direction is important. A scalar is a quantity in which a direction is NOT important.
Yes, a scalar product can be negative if the angle between the two vectors is greater than 90 degrees. In this case, the dot product of the two vectors will be negative.
Scalar is a type of quantity which contains magnitude only and has no direction. For example: distance and speed

can a magnitude of a vector has negative value?
All scalar quantities have magnitudes; what scalars don't have is direction. The magnitudes can take any value, +ve or -ve (or zero).
scalar cannot be added to a vector quantity
Velocity is a vector quantity that includes both magnitude (speed) and direction. Thus, velocity can be zero if there is no motion, but speed is the magnitude of velocity and cannot be negative. Speed is always a positive scalar quantity, so it cannot be zero if there is any motion at all.
radius is a scalar quantity, it can not have a negative value.
Displacement is a vector quantity which refers to the distance moved with respect to a position. If the position is home, once you are home, displacement is zero. Distance is a scalar quantity which refers to the distance moved. This can be counted from the start to end. Since scalar quantity cannot go negative (it cannot drop but only rise), it can never be zero. If you moved 1 metre north then 1 metre south, displacement is zero metre but distance is 2 metre.

A scalar quantity may have positive and negative values - it is simply a real number. But it doesn't have a direction. Think of it as a "vector in one dimension" - whereas the usual vectors have at least 2 dimensions.
temperature is a scalar quantity................
It depends upon the condition.But basically, to be a vector, the physical quantities needs to follow vector algebra.but current dos not follow it so it is scalar quantity.
