10. the applied force required to push something across a surface as friction increases? what's the word for the blank?

I think the word would be "increases" because if you think about it technically, you know that friction is always going to move against your force so if the force pushing against you is larger, then you would also need to exert more force.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

f is prop to m1xm2 double m1 double force
