A light meter, because illu is a root for light
Chemical Potential Energy is released when chemical bonds between atoms are broken (like covalent and ionic) and is released mainly as thermal
<span>Elastic Potential is released when the molecules in the material are allowed to go back to there original form, and is released mainly as kinetic</span>
Explanation:
It is given that,
Fundamental frequency, f = 220 Hz
(a) We know that at 0 degrees, the speed of sound in air is 331 m/s.
For open pipe, 
l is the length of pipe
Also,
(b) Let f' is the fundamental frequency of the pipe at 30 degrees and v' is its speed.
v' = 348.71 m/s
So, 
f' = 232.4 Hz
Hence, this is the required solution.
Because less energy is being wasted. non-renewable resources will last longer.
the cost is kept lower. hope it helps :)
Answer:
1. sediment layering and compacting on top of each other and solidifying
2. sediment layering and compacting (not as much) on top of each other and solidifying, just not as much
