The pressure exerted by a block of wood is 40 pa. If the force exerted by the block is 80N what is the surface area of the wood?

Pressure = 40Pa

Force = 80N

Surface area = ?

Pressure = Force/Surface area

hence Surface area = Force/Pressure

Surface area = 80N/40Pa = 2m^2.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

  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
