What is the sign convention that results from the above definitions?
The sign convention resulting from the above definitions is that positive values indicate a direction or quantity that is considered to be in the same direction as the chosen positive axis, while negative values indicate a direction or quantity that is opposite to the chosen positive axis.
What does a positive or negative value mean in physics?
In physics, a positive value typically indicates a quantity that is greater than zero, while a negative value indicates a quantity that is less than zero. Positive and negative values can represent different physical properties, such as direction, charge, energy, or force, depending on the context in which they are used.
Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
What is the Hounsfield unit of water?
The Hounsfield unit of water is 0. It serves as the reference point in Hounsfield units, with densities higher than water having positive values and lower densities having negative values.
What is a quantity having continuous values?
A quantity having continuous values is one that can take on any value within a certain range, including decimal and fractional values. Examples include temperature, weight, height, and time. These quantities can vary continuously without any abrupt jumps between values.
Can a body have positive distance but negative speed?
First of all you must be familiar with scalar and vector quantities. A scalar quantity is a physical quantity having only magnitude example length. A vector quantity is a physical quantity having both magnitude and directions. Now speed and distance are both scalar quantities which means their values are always positive. But if you considered velocity then there can be a negative value. Velocity is measured w.r.t the direction the object is going. Conventionally the direction is negative if the object is moving to the left of the initial point and positive for the other way.

Why work is negative its is scalar quantity?
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.
What do you do when subtracting a positive and a negative?
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.
Can the magnitude of a vector has negative value?
can a magnitude of a vector has negative value?
For what values of n is -2n positive?
[ -2n ] is positive for all negative values of 'n' .
Can probability values be negative?
No. Probability values always have to be positive.
When you add a positive number by a negative number will it be negative or positive?
That depends on the values of the given numbers but a positive number multiplied by a negative number will be negative
Are electron affinity values usually positive or negative numbers?
Positive for nonmetals and negative for metals
How can you define zero?
Zero is the figure or symbol 0, which in the Arabic notation for numbers stands for the absence of quantity. It is a mathematical value intermediate between positive and negative values.
How do you find the quadrant number of a point?
If the points have both positive y-values and x-values it is quadrant 1 If the points have a negative x-value and a positive y-value it is quadrant 2 If the points have both negative y-values and x-values it is quadrant 3 If the points have a positive x-values and a negative y-value it is quadrant 4
