Is any quantity having a positive and negative values a vector?
No, vector, besides a value, has also a direction.
Is pressure a scalar quantity justify with an example?
Yup! We know that the scalar quantity is a quantity which is having magnitude but not having "DIRECTION" pressure is a scalar quantity for the reason that it's not having any direction Means it is directionless...... Have you ever heard saying anyone that the pressure applied was 730 torrs in west , east or north south direction?????????> No, it is IMPOSSIBLe.....
Is volume a vector or scalar?
Density is a scalar quantity. We don't talk about the density of a material as having direction, which is a characteristic of a vector quantity.
When the same quantity of heat is added per unit as does a substance having a lower specific heat warm more or less than a substance having a higher specific heat?
specific quantity
What is the physical significance of gradient of any physical quantity?
the gradient of a scalar function of any quantity is defined as a vector field having magnitude equal to the maximum space rate of change of the quantity and having a direction identical with the direction of displacement along which the rate of change is maximum.
Is time discrete or continuous?
Continuous. Discrete variables are only expressed as integer values, whereas continuous is, as its name suggests, continuous.
Is any quantity having a positive and negative values a vector?
No, vector, besides a value, has also a direction.
What is example of a quantity that is continuous?
People's heights.
Classification of variables according of continuity of values?
Not continuous => Discrete variable. Continuous => Continuous variable.
What is data analog?
analog data are continuous and take continuous values
Is having a tattoo continuous or discontinuous?
Continuous or might be discontinuous.
Does the sine function appear to be continuous?
Yes, it does "appear" to be continuous, by the simple fact that it is continuous for all values of the input.
What is a quantity that can have different values?
A variable.
What is the difference between a continuous and discrete quantity in statistics?
A continuous number can take any value, such a 1.234, or 3.5, or 10.11. Height is usually a continuous quantity (even though height cannot be negative, it is still continous). Time is also usually considered continuous. Whereas a discrete number must take certain values, such as (1, 1/2, 3, 4, 5 etc. . for shoe sizes) or (1, 2, 3 etc.. for amount of people). Since you cannot get .2 of a person, or -3 pencils or something equally illogical .
What is a quantity having magnitude and direction?
vector Quantity
What is continuous variate?
A variable defined on a continuous interval as opposed to one that can take only discrete values.
Have in the past continuous?
Was/were having.
