A brick is initially at rest on top of a rough horizontal surface. The brick is pushed by a force F=25N parallel to the surface and starts to move. The weight of the brick =28N. What must the coefficient of static friction of the brick with the surface be less than

their crystal patterns have been disrupted by stress

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

it's a b and
