Producido a partir de un experimento de laboratorio ido mal, las tortugas adolescentes Leonardo, Michelangelo, Donatello y Raphael viven en las alcantarillas bajo Nueva York. Aunque su sensei roedor, Splinter, aconseja no mostrarse sobre el suelo, los hermanos amantes de la justicia y que comen pizza no pueden permanecer ociosos mientras el malvado Shredder y sus secuaces aterrorizan a la ciudad. Con ayuda de la intrépida reportera April O'Neil (Megan Fox) y su camarógrafo (Will Arnett), las Tortugas salieron a salvar a Nueva York.
espero que esto ayude :)
The relationship between the kinetic energy of molecules in an object and the objects temperature is: as temperature increases, the kinetic energy of the molecules increases.
I think this is simply the stage of observation
Well if we don't recycle paper and use it up too fast, more trees would be chopped down, which is not good for the environment. Plastic can be dangerous and release toxic chemicals so we have to handel it well. Btw, what grade are you in?
Answer:
a. Wavelength = λ = 20 cm
b. Next distance of maximum intensity will be 40 cm
Explanation:
a. The distance between the two speakers is 20cm. SInce the intensity is maximum which refers that we have constructive interference and the phase difference must be an even multiple of π and equivalent path difference is nλ.
Now when distance increases upto 30 cm between the speakers, the sound intensity becomes zero which means that there is destructive interference and equivalent path is now increased from nλ to nλ + λ/2.
This we get the equation:
(nλ + λ/2) - nλ = 30-20
λ/2 = 10
λ = 20 cm
b. at what distance, sound intensity will be maximum again.
For next point calculation for maximum sound intensity, the path difference must be increased (n+1) λ. The distance must increase by λ/2 from the point of zero intensity.
= 30 + λ/2
= 30 + 20/2
=30+10
=40 cm
