Answer:
The possible thickness of the soap bubble = 
Explanation:
<u>Given:</u>
- Refractive index of the soap bubble,
- Wavelength of the light taken,
Let the thickness of the soap bubble be 
.
It is given that the soap bubble appears very bright, it means, there is a constructive interference takes place.
For the constructive interference of light through a thin film ( soap bubble), the condition of constructive interference is given as:
where 
is the order of constructive interference.
Since the soap bubble is appearing very bright, the order should be 0, as 
order interference has maximum intensity.
Thus,
It is the possible thickness of the soap bubble.
Answer:
Explanation:
It transmits energy into the medium through its vibration. More energetic vibration corresponds to larger amplitude. The molecules move back and forth more vigorously. The loudness of a sound is also determined by the sensitivity of the ear.
Answer:
tension is 0.692 N
magnetic force is 0.401 N
Explanation:
given data
mass = 57.5 g = 0.0575 kg
long = 38.8 cm = 0.388 m
displace = 22.5 cm = 0.225 m
to find out
free-body diagram , tension and magnetic force
solution
we consider here angle is θ
so free body diagram is attach below
and
here cosθ = x/l
so θ = cos^-1 ( 0.225 / 0.388)
θ = 54.6°
so tension from net force is
net vertical force
t sinθ - F(g) = 0 ...........1
t = F(g) / sinθ
t = mg /sin54.6
t = 0.0575 ( 9.8) / sin54.6
t = 0.692
so tension is 0.692 N
and
net horizontal force
- t cosθ + F(magnetic) = 0 ....................2
t cosθ = F(magnetic)
put here all value
F(magnetic) = 0.692 × cos 54.6
F(magnetic) = 0.401
so magnetic force is 0.401 N

Answer for the question :
"Consider the two level (AND-OR) function f1(A, B, C, D) = AC0D + AB0D0 and two level (OR-AND) function f2(A, B, C, D) = (A+B +D0 )(B0 +C +D0 ). Find the following two level circuits expressions for f1 and f2. (Hint: use both SOP and POS form of f1 and f2"
