英文物理题 急需
By mistake, one litre (1000 cm3) of oil was dumped into a swimming pool that measures 25.0 m by 30.0 m. The density of the oil was 0.750 g/cm3. How thick was the resulting oil slick? Be careful with significant figures and scientific notation.
油覆盖在游泳池的表面,要求油膜的厚度,就要知道油的体积V和游泳池的表面积S。 V=1000 cm3=10^-3m3 S=25*30=750m 厚度h=V/S=1.33*10^-6m=1.33*10^-4cm 油的密度0.750 g/cm3不需要用到,it was not a significant figure.
