4(ii) State two precautions taken to ensure accurate result. 4(iii) If smooth spherical ball of brass material having a radius of 3mm fall through certain
liquid having coefficient of viscosity of 8x 10-NS/m². If the density of the brass
material is 8.6x10 kg/m", estimate its terminal velocity
(v)? Assume that the density of the liquid is 5.7x10kg/m.​

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
