Since this situation can be thought of as a direct variation. multiply 20000 with 100 and divide the product with 1500.
Sounds are reflected best when bounced off the flat surfaces.
<h3>What is a sound wave?</h3>
A sound wave is produced when a medium begins to vibrate. When an entity vibrates, a pressure wave is formed, which causes sound.
Since sound waves cannot easily pass through hard surfaces, they bounce off them instead, reflecting back to the source which they first came from.
When sound is reflected off of flat surfaces, it does so most effectively.
Hence the flat surface is the correct answer.

Answer:
Chromosphere
Explanation:
The Chromosphere is one of the important internal layers of the sun, which lies above the layer of Photosphere. The Chromosphere has a thickness of about 3 to 5 km having a very high temperature, ranging from about 5000 to 20,000°C. Due to this extreme temperature and continuous nuclear fusion process that takes place at the core of the sun, there forms the reddish colored layer, which is usually not visible but can be observed during the time of a total solar eclipse, by the use of an ultraviolet telescope.
Answer:
1.10^6 kg of mass per second
Explanation:
All energy lost by the sun comes from nuclear fusion.
Sun loses energy at 2.5*10^{19}J per hour, that is 9*10^{22}J/s
To find the mass lost by the sun in liberation of energy you use the famous Einstein's equation:
hence, the sun liberates 1.10^6 kg of mass per second
