They are infrared waves which mean they take the form of heat.
If you pack more mass into a certain volume, the density will increase.
Answer:
it comes from your knowledge and the information you have to get the reason why that is the answer so you are putting together things that you already know what the new information you have
Answer:

Explanation:
Given:
- mass of skier,

- initial velocity of skier,

- height of the hill,

- spring constant,

<u>final velocity of skier before coming in contact of spring:</u>
Using eq. of motion:



<u>Now the time taken by the skier to reach down:</u>



<u>Now we calculate force using Newton's second law:</u>




<u>∴Compression in spring before the skier momentarily comes to rest:</u>




The answer would be the Scientific Method.
