The best way to measure it usually is to use a beaker or graduated cylinder.
Answer:
parts of outer space where there is no air or atoms
Explanation:
Matter is made up of atoms. Similar to how your cells make your body, atoms make up all and everything. This since outer spaces doesn't have atoms, it doesn't have matter as well (at least not the normal matter, it does have dark matter, which is a whole can of worms that should not be opened)
Endothermic reaction : A reaction in which the system absorb energy, usually in the form of heat
the one that is an endothermic reaction is : D. Thawing ice
hope this helps
The oxidizing agent is the one that is reduced in the reaction. In this reaction, the charge of Cu falls from +2 to zero charge (neutral atom in the right side). Hence, CuO is the oxidizing agent. The reducing agent, the one being oxidized is carbon from zero charge to +4. The answer is CuO.
Answer:
<em>Sonar can be used to measure the depth of the seabed or the distance of any object, animal or a man-made vessel any other objects </em>
Explanation:
- A sound wave or sound pulse is projected into the water.
- If any object tends to come in the way of the pulse, an echo is produced or the signal is reflected back.
- A transducer measures the strength of this signal and hence determines the depth of the object or the sea.
This is much better way of measuring distances under the sea since light alone is not able to pierce through the ocean after a certain distance.
A powerful sonar blast can help in taking multiple measurements at a time, while even a laser will find it difficult to reach below 3 km of depth.
