A physics major is cooking breakfast using a steel spatula and a Teflon frying pan. The coefficient of kinetic friction between the two materials is 0.04 and the normal force is 8N. What is the magnitude of the kinetic friction force between the two surfaces .

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.

    5.5 n======    assuming that      we have      m = 0.145 kg    a = 38 m/s²therefore    5.51 n, but two significant figures.final answer: 5.5 n
