Answer:Because it likes to repel and attract opposites
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
Answer:
Yes

Answer:
you
Explanation:
cause your reading this and breathing
I'm pretty sure what you are trying to ask for is radiative energy, light energy, and electronic energy
<span>Radiative since the microwave is releasing radiation </span>
<span>Light since there is light inside the microwave.</span>
Electronic since it is plugged in and uses electricity.
<span>You can also use sound, but I don't think every microwave makes sound. </span>
