A horizontal force 20N is required to just slide a block of mass 6kg on a horizontal platform. The coefficient of limiting friction between the block and the platform is ?( g = 10 m/s).​

0.33

Explanation:

R= 60N

coefficient of limiting friction = F/R

= 20/60 = 0.33

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
