What is the role of the air spaces in insulating materials? Select all that apply. They trap heat in the spaces. They puts gaps between the particles to slow down conduction. They dissipate energy faster.

Is it true or false that wave interference only occurs with transverse waves?

There have been several proposed atomic models during the last 150 years. Which model best illustrates the Bohr model. This model suggests that an atom's electrons orbit the nucleus in fixed patterns, much like the planets orbit the Sun.
