Q1. A 2.0 kg piece of wood slides on the surface. The curved lateral sides are perfectly smooth (no resistance), BUT the horizontal bottom is rough and has a coefficient of kinetic friction μk = 0.20 with the wood. The piece of wood starts on the left side from rest at an height of 4.0 m above the bottom part and slides down along the side and then along the rough bottom. Where will this wood eventually come to rest?
Q2. Whole blood has a surface tension of 0.068 N/M & a density of 1050kgm-3.what weight can whole blood rise in a capillary blood vessel that has radius 2.0 x 10-6 if the contact is zero?
