Calculus purge - Lab Report ExampleQ2. A scalar sum of m unrivalledy can be either ostracize or zero or positive. This depends on choice of the reference situation or zero point. survival of the fittest of reference or zero comes from convention and / or convenience. Suppose round one(a) is conduction an experiment and notice nearly change with time then he can choose zero time as per his convenience and there is nothing that can bar his choice of zero or reference point for time, if some choice of zero reference point is offering him some convenience in formulating some equation or like that he is free to choose it. Once he has assigned some zero or reference point for time, the time corresponding to all the preceding events becomes zero. In occurrence we write 1999 AD which is nothing but +1999 year and similarly a date like 530 BC is as good as -530 years.Similarly, another scalar quantity temperature is often measured in prohibit with melting point of ice being 0o Celsi us and all the temperatures below it being negative temperatures. Similarly one can find many instances where scalar quantities are have negative values.Q3. A vector quantity is formed by vector addition of its components. Therefore, if any of the components has a non-zero magnitude the vector will excessively have a non-zero magnitude. So it is not possible to have a vector of zero magnitude if one of its components is not zero.However, under some operations, in which the magnitude of the resultant depends not only on the magnitude of the individual vectors but on the angle between the two vectors as well one can get a resultant of zero magnitude. This is illustrated below.This mode resultant of two vectors with unequal magnitude can be zero under scalar product provided the two vectors are mutually perpendicular. physically work done by a force is zero if the displacement caused by it is normal to its direction.This means resultant of two vectors with unequal magnitude can be
