Q1Physical Quantities and UnitsFree sample

(a)

Compare scalar and vector quantities.

(b)

The radius of a small sphere is determined from a measurement of the volume of the sphere.
The sphere is submerged in water, displacing some of the water into a measuring cylinder as
shown in Fig. 1.1.

Fig. 1.1

The measured volume of displaced water is $(28.0 \pm 0.5)\ \text{cm}^3$ .

Calculate:

(i)

the radius, in cm, of the sphere

radius = ______ $\text{cm}$

(ii)

the percentage uncertainty in the radius of the sphere.

percentage uncertainty = ______ $\%$
