what force is required to act on a small piston with an area of 60cm ^ 2 to create a compressive force of 10kN in a large press with an area of 1m ^ 2

no. dot product   =0 when vecs at right angles

  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
