Answer:

When the inner bag of water is broken by squeezing the package, it dissolves the solid in an endothermic reaction. This reaction absorbs heat from the surroundings, quickly lowering the pack's temperature.

Explanation:

Uh, yea.

From the atomic clock that utilizes C-133 which has an approximate frequency of 9.193 x 109 Hz. The wavelength of the energy is calculated to be 0.0326m.

From the given information:

  • The frequency f = 9.193 × 10⁹ Hz = 9.193 × 10⁹ 1/s
  • The wave speed c = 3.00 × 10⁸ m/s

Recall that:

The wavelength is the spatial successive distance between two crests of a wave and can be expressed by the formula:

\mathbf{\lambda = \dfrac{c}{f}}

\mathbf{\lambda = \dfrac{3.00 \times 10^8 \ m/s }{9.193 \times 10^9 \  1/s}}

\mathbf{\lambda =0.0326  \ m}

Therefore, we can conclude that the wavelength of the atomic clock is 0.0326m. As such Option D is correct.
