What is the density of a solid that has a mass of 9.2 grams and a volume of 12.3 cm3 ? Would this object float or sink in water?
cluponka [151]
  • Mass=9.2g
  • Volume=12.3

\boxed{\sf Density=\dfrac{Mass}{Volume}}

\\ \sf\longmapsto Density=\dfrac{9.2}{12.3}

\\ \sf\longmapsto Density=0.74g/cm^3

  • Density of water =1g/cm^3

It will float in water

To explain the photoelectric effect, Albert Einstein linked the photoelectric effect to an idea from which scientist?
blondinia [14]
Based upon Max Planck's theory of black-body radiation, Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant, later called Planck's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.
