A grаin оf pоllen sitting оn the surfаce of wаter is frequently hit by surroundingmolecules, causing the pollen to follow a random-looking zig-zag trajectory (knownas Brownian motion).The pollen grain first moves 0.247 mm at an angle of 0.00o relative to a given axis. Acollision takes place, after which the grain moves an additional 0.310 mm at an angleof 71.0o above the axis.What is the magnitude of the pollen grain’s total displacement?
