Answer:

At different times

Explanation:

The echo returns at different times, but faster in water. This is because water particles are bound closer and this makes them transmit vibration energy from one particle to the next quickly. An echo is a sound wave and sound waves are longitudinal waves that occur by the collision of particles to move the vibrations along, and this is why they move slower in air.

Answer:

valid.

Explanation:

Valid is something effective, legally binding or able to withstand objection.

In deductive reasoning, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. It is not required for a valid argument to have premises that are actually true, but to have premises that, if they were true, would guarantee the truth of the argument's conclusion. Valid arguments must be clearly expressed by means of sentences called well-formed formulas. The validity of an argument can be tested, proved or disproved, and depends on its logical form.

An argument is a set of statements expressing the premises and an evidence-based conclusion.

Answer:

<em>Primary sources are firsthand, contemporary accounts of events created by individuals during that period of time or several years later (such as correspondence, diaries, memoirs and personal histories). These original records can be found in several media such as print, artwork, and audio and visual recording. Examples of primary sources include manuscripts, newspapers, speeches, cartoons, photographs, video, and artifacts. Primary sources can be described as those sources that are closest to the origin of the information. They contain raw information and thus, must be interpreted by researchers.</em>

Examples of secondary sources include textbooks, articles, and reference books.</em>
