Physics

erica [24]3 years ago
5 0
Frequency is given in units of Hertz (Hz) and is defined as the number of cycles per second.  The sound wave has 30,000 cycles per second, so its frequency is 30,000Hz.
This is more conveniently expressed as 30kHz, where the k indicates a multiplier of 1,000.

What change happens when matter<br> changes states?
Snowcat [4.5K]
Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.

Which type of radiation can reach the furthest?<br> A. Beta<br><br> B. Gamma<br><br> C. Alpha
Mashutka [201]

Answer:

C. Alpha

Explanation:

Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.
