Polly is pushing a box across the floor with a force of 30 N. The force of gravity is -8 in, and the normal force is eight in. Which value could describe the force of friction and Polly could not move the box

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.

Sorry i don’t know what to do
