Answer:

E = hv

Explanation:

  • The photoelectric effect is a phenomenon when the electromagnetic waves of a particular wavelength strike on the metal plate like zinc, it ejects the free electrons.
  • The ejected electrons have the kinetic energy and this energy is responsible for the electric energy.
  • The kinetic energy of the emitted electrons is linked with the frequency of the incident rays.
  • If the rays hitting the metal plate is below the minimum required threshold value, the photoelectrons are not ejected.
  • The photoelectric equation is given by

                            E = hν - ∅

Where, ∅ is the minimum energy required to remove an electron.

True or false? One reason gases are easy to compress is because their particles have higher energy.
erik [133]

True

Why are gases easy to compress in terms of particles?

Particles are far apart from each other because there are very weak forces of attraction between them. They move fast in all directions. Because of this, gases don't have a definite shape or volume and fill any container. Because there is lots of free space between particles, gases can easily be compressed.
