The phrases that describe radioactive elements are;

-occur in nature

-decay at a constant rate

- have a half-life that determines their rate of decay

Radioactive elements are elements whose nucleus are liable to decay overtime followed by the release of energy (alpha particles, beta particles, or gamma rays) and conversion to different elements. Every element that has atomic number greater than 83 is radioactive. Most radioactive elements occur in nature. Examples include uranium, radium and thorium. Radioactive elements have a half-life that determines their rate of decay

Which of these lists is arranged in order from smallest wavelength to longest wavelength?
guajiro [1.7K]

Answer:

b. wind waves, seiches, tsunami, tides.

Explanation:

The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave.  Usually, the bigger the wave, the greater the wavelength.

wind waves: small waves caused by the wind.  These waves tend to be small and with a short wavelength.

seiches: are usually waves on a lake or other closed water bassin.  They can be pretty high from a human perspective, so they are definitely bigger than wind waves.

tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.

tides: yes, a tide can be considered as a huge wave... that's running throughout the planet.  We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.

Nady [450]

Answer:

Explanation:

The Relationship between Rainfall and Temperature.
