In this case gravity does not actually push the block into the wall and the force of m g is acting perpandicular to the wall which means only the horizontal force of 12n is acting to be a multiplier in the friction equation.
If the block were in contact with the ground and not the wall the friction force would be calculated by 9 81 0 5 u friction force.
The cafepress line up of wall clocks is huge and ever growing delivering a large variety of unique decorative clocks for your home or office.
