What is the reliability of measurement of length using a metre scale ?

Assertion (A): In Ohm's law experiment, the reading of voltmenter and ammeter are 13.5V and 0.40A respectively, then the measured computed value of R is 33.75Omega upto correct SD 's Reason(R ): The reliability in computed value can not be more than the reliability in measured values.

If the mass of a radioactive sample is doubled, the activity of the sample and the disintegration constant of the sample are respectively
