Answer:
a = 0 m/s²
Explanation:
Static friction = Fn*μ = 50 * 0.5 = 25 N
25 N > 20 N
As the static friction is more than the force applied, the box will not move ;
a = 0 m/s²
Answer:
(a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.
Explanation:
Given that,
Refractive index = 1.20
Wavelength = 496 nm
Next wavelength = 386 nm
We need to calculate the thickness of the glass
Using formula for constructive interference
Put the value into the formula
In first case,
.....(I)
In second case,
.....(II)
From equation (I) and (II)
Put the value of m in equation (I)
The thickness of the glass is 868 nm.
(b). We need to calculate the wavelength
Using formula of constructive interference
Put the value into the formula
Hence, (a). The thickness of the glass is 868 nm.
(b). The wavelength is 3472 nm.

Answer: I hope i can help you today!
Explanation:
A bunch of Musical instruments have been using Resonance to make the sound louder like to amplify the instrument of their sound waves, For example- The strings that go on the Violin would be an Acoustic resonance and so is the Body of the violin cause that is where the sound waves hit to make that beautiful sound that comes out once you play the instrument!
