Answer:

d. radio telescope

Explanation:

A radio telescope allows the analysis of radio light waves by first,<em> collecting them, </em>then<em> bringing them to a focus </em>and<em> amplifying them </em>in preparation for analysis. They are the largest telescope in the world and are said to have the ability to observe <em>light with long wavelengths</em>. This makes them different from optical telescopes that are meant to observe<u> visible lights</u>. This allows the astronomers to<em> study the composition of the heavenly bodies in the universe.</em>

alekssr [168]

Explanation:

It is based upon the fact that " The light travels faster then sound." As the speed of light is faster then the speed of sound, light travels 300,000 km per second and sound travels 1192 km per hour. That is why we observe the lightening first and hear the the sound of thunder later.

        You can do this experiment by yourself. Once you see the lightening start counting the seconds until you hear the sound of thunder.Then divide the seconds by 5, you will find out how many miles away the lightening strike was.

Elena L [17]

The amount of energy required to raise the temperature of one gram of water by one celsius degree is called a calorie.

<h3>How can you define calorie?</h3>

In physics, we can define it as a unit of measurement that defines the amount of energy to raise the temperature of 1 gram  of water by 1°C. Each material has its unique calorie, however by definition we use water as it is the lowest of all the elements.

Normally, calorimetry is directly linked with the thermal capacity that an element has to contain heat.
