Why does sonar use ultrasound rather than sound?

Physics

Answer;  Ultrasonic waves (sounds having frequency greater than 20,000 Hz) are used in sonar because: ... Ultrasonic waves can penetrate water to long distances (because of their high frequency and very short wavelength), but ordinary sound waves or infrasonic waves cannot penetrate water to such long distances.

What force controls the isostatic adjustment of Earth’s crust?
Alina [70]
The force that control the isostatic adjustment of the earth's crust is THE FORCE OF GRAVITY.
The isostatic adjustment of the earth crust refers to continuous movement of the earth crust or its deformation as a result of the force of gravity which act on it. The earth crusts that are located at the upper and a the core of the earth usually set up a balance between them which is called isostatic equilibrium.

What would be the best design for an experiment that tests how much water expands when frozen?
galben [10]

B. Purchase a small plastic container and mark 1-ounce increments on the outside to determine volume. Pour 5 ounces of water into the container, and place in the freezer for 8 hours. Compare the frozen or ending volume with the liquid or beginning volume.

<h3>How much water expands when frozen?</h3>

Ice is less denser than the liquid form. Water is the only known non-metallic substance that expands when it freezes because it is the unique property of water. Water density decreases and it expands approximately  about 9% by volume. For calculating the expansion of water, plastic container is the best option. We know that water expands when the water freezes because it is a unique property of water which allows the survival of aquatic organisms.

So we can conclude that option B is the right answer.

What is happening if energy input remains constant and voltage remains the same in a circuit, but the current decreases?
DENIUS [597]
<span>Ohm's law deals with the relation between voltage and current in an ideal conductor. It states that: Potential difference across a conductor is proportional to the current that pass through it. It is expressed as V=IR. The correct answer from the choices listed above is option A. The resistance has increased. </span>
