If smooth spherical ball of brass material having a radius of 3mm fall through certain liquid having coefficient of viscosity of 8x 10'NS/m. If the density of the brass
material is 8.6 x10 kg/m', estimate its terminal velocity
+)? Assume that the density of the liquid is 5.7x10'kg/m.​

viscous liquid of density 2×103kg/m3, and η=0.1N-s/m2. The distance moved by the ball in t=0.1sec after it attains terminal velocity is. Updated On: 26-6-2020.

Explanation:

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
