All of the following show friction as a useful force, except
Troyanec [42]

having to push a rough and heavy box across the floor to move it

Explanation:

Friction is not a useful force because we have to exert even more force to push a body that is rough and heavy across the floor to move it.

  • Frictional force is a force that opposes the motion of a body.
  • It costs more and uses more energy to push a rough and heavy box on surface because of friction.
  • This wastes energy in systems that deals with pushing.

Friction is useful in that:

  • the heat energy produced when two surfaces rub together  is very useful.
  • the friction between your feet and the floor keeping you from slipping  and makes walking possible.
  • the tread on tires helping the moving vehicle slow down and stop when necessary.

Rafaela is a physical education teacher and has2525 girls and 3535 boys in herclass.She wants to divide the class into teams of
Paha777 [63]

-- The greatest common factor of 2525 and 3535 is 5.

-- So the greatest possible number of teams is 5.

-- Each of the five teams will have 505 girls and 707 boys.

-- Rafaela is a superwoman !  She's handling more kids in that class than there were in my whole high school !

She has 6,060 students in her class, so I'm not surprised that she wants to divide the class up into smaller groups.  

But come on !  She's going to form 5 teams, and she thinks that her job will be easier that way, because each team will have 'only'  1,212 students on it !

And these are all in one class !  If Rafaela is a physical education teacher, then SURELY she's teaching more than one class !

Or maybe not.  I'll betcha whenever Rafaela is teaching her physical education class, all the other teachers are taking it easy, because Rafaela is responsible for every student in the school that hour.

And possibly several OTHER schools in town too.
