For example, A will be scalar quantity and A will be a vector quantity. Let Ax and Ay be the rectangular components of a vector A then A=Ax+Ay This means that vector A is the resultant of vectors Ax and Ay. A is the magnitude of vector A, and similarly Ax and Ay are the ...
The attribute Q'delayed(T) denotes a quantity with the value of quantity Q delayed by time T. The quantity can be of any type that is legal for a quantity, and the time parameter must be a static expression yielding a non-negative real number. Thus, the amount of the delay must be ...
Can a scalar be negative? The range of scalar quantity is the whole number line, but that scalar quantity takes only one value from the whole number line, that is the real number category. Now, as the real numbers include both, positive numbers as well as negative numbers,a scalar can ...
By definition, a scalar quantity is a number — negative, positive, or zero — that refers to the magnitude of the quantity. Every scalar quantity has a unit that gives it significance and relates to the measured quantity. Thus, to understand what a scalar quantity is, look for a number ...
Scalar Quantity Examples Some examples of scalar quantities are distance, density, energy, and time. A distance, for example, could be represented by a numeral and a unit of measure, such as 150 km or 10 miles. Energy can be measured in joules (J) such as 8.70 J of energy. Density ...
Assertion : A vector can have zero magnitude if one of its rectangular components is not zero. Reason : Scalar product of two vectors cannot be a negative quantity. View Solution What do you understand by the scalar product of two vectors ? Write the formula, explaining the symbols used....
Scalar, a physical quantity that is completely described by its magnitude. Examples of scalars are volume, density, speed, energy, mass, and time. Other quantities, such as force and velocity, have both magnitude and direction and are called vectors. Sca

The cross sections of these two processes are quite large [11, 12], so both the singly-charged and the doubly-charged scalars are produced in a large quantity at the LHC.1 More importantly, the decays of H++ could give rise to unique signatures that in turn can be used to constrain ...
The complex quantity λ = λ′ + iλ″ is a scalar and cannot be changed. But the quantity μ can be given any nonzero value by a suitable complex rotation; we can therefore, without loss of generality, assume it to be real. As a result we get the following canonical type for the...
