Answer: It goes inside filling most of it .
Explanation: This happens because the bottle is empty and the bucket is full of water.
Answer:
a. -8 cm
Explanation:
= distance of the object = 4 cm
= distance of the image = ?
= focal length of the converging lens = 8 cm
using the lens equation
= - 8 cm
20-60minutes
Explanation:
Within 10-20minutes after a drink is consumed all of the alcoholic content has probably been absorbed into body.
Alcohol is absorbed into the body much more fast.
- It does not undergo digestion process like food.
- It can easily be absorbed into the blood stream.
- Alcohol is readily absorbed and carried round into the body.
- It doesn't get processed like food in the body where they pass through the digestive system.
- The body sees alcohol as nutrient.
- It carries it to the brain and other parts of the body.

Explanation:
the formula to find its is 1÷2*gt^2
Answer:
t< 75 nm
Explanation:
A soap bubble is a thin film where when the beam enters the film it has a 180º phase change due to the refractive index and the wavelength changes between
λ = λ₀ / n
In the case of constructive interference in the curve of the spherical film it is
2 nt = (m + ½) λ₀
Where t is the thickness of the film and n the refractive index that does not indicate that we use that of water n = 1.33, m is an integer. The thickness of the film for the first interference (m = 0) is
t = λ₀ / 4 n
A thickness less than this gives destructive interference.
Let's look for the thickness for the visible spectrum
Violet light λ₀ = 400 nm = 400 10⁻⁹ m
t₁ = 400 10⁻⁹ / 4 1.33
t₁ = 75.2 10-9 m
Red light λ₀ = 700 nm = 700 10⁻⁹ m
t₂ = 700 10⁻⁹ / 4 1.33
t₂ = 131.6 10⁻⁹ m
Therefore, for all wavelengths to have destructive interference, the thickness must be less than 75 10⁻⁹ m = 75 nm
b) a film like eta is very thin, it is achieved when gravity thins the pomp, but any movement or burst of air breaks it,
