Calculate the following round off to the correct number of significant figures and express your result in scientific notation. a). (200.9)(569.3) .513)(62.3x10^7)

A) 1.144×10^5

B) 3.20×10^2

Explanation:

A) Both of the numbers are in 4 significant figures, so we write answer in 4 significant figures.

B)Both of the numbers are in 3 significant figures, so we write answer in 3 significant figures.

  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
