1. The radius of a solid sphere is measured to be (6.5 ± 0.2) cm. Determine the volume of the sphere with its uncertainty.
2. A resistor is marked as having a value of 5.9 ± 2%. The power P dissipated in the resistor, when connected in a simple electrical circuit, was to be calculated from the current in the resistor, which measured as (1.40 ± 0.05) mA. What is the value of calculated P together with its associated uncertainty?
