What do lenses do?
Dovator [93]
A convex lens makes light rays converge (come together) at the focal point or focus. The distance from the center of the lens to the focal point is the focal length of the lens. Convex lenses are used in things like telescopes and binoculars to bring distant light rays to a focus in your eyes.

A cylindrical diving bell is open at the bottom and closed at the top, and is 5m tall. The bell is open to atmospheric air until
laila [671]

Answer:

a)   y = 0.35 m,    b) hydrostatic balance

Explanation:

a)  For this fluid mechanics exercise, let's use that the pressure at a given level is the same, let's set a level on the bell shape.

The pressure inside is

             P_interior = P₀ + ρ g h ’

The pressure outside

             P_exterior = Pₐ + ρ g h

as the point is at the same level the pressures are equal

             P_interior = P_exterior

             P₀ + ρ g h ’= Pₐ + ρ g h

             h ’= (Pₐ- P₀)  + ρ g h  

To calculate P₀ they indicate that the pressure increases 10⁵ Pa for every 10 m, we use a direct rule of proportions or rule of three

            P₀ = 10⁵ (40 + h ’) / 10 = 4 10⁵ + h’ 10⁴

the positive sign is because the water inside the hood also increases the air pressure.

we substitute

             (4 10⁵ + h’ 10⁴) + ρ g h’ = Pₐ + ρ g h

             h’ (ρ g + 10⁴) = Pₐ - 4 10⁵ + ρ h h

           

            h’ (1000 9.8 + 10⁴) = (1 10⁵ -4 10⁵) + 1000 9.8 40

            h' (1.98 10⁴) = -3 105 + 3.92 10⁵

            h’ =  - \frac{0.92 \ 10^5 }{1.98  \ 10^4  }

            h ’= -4.65 m

as the hood is only 5 m high, the free air space is

            Y = 5 - 4.65

             y = 0.35 m

it is very little free space

B) The pressure outside and inside the hood is the same, the water rises inside the hood until the pressures equalize and at this point the force is equal and in the opposite direction, which is why the system is in hydrostatic balance.

The

The structure of an individual  molecule will determine which substance  will dissolve.

<u>Option: A</u>

<u>Explanation:</u>

Once a solvent disintegrates, the single atoms, molecules or ions communicate with the solvent, become solved, and are able to diffuse in the solution independently. However, this is not a unidirectional method. When the molecule or ion collides with the surface of an undissolved solute particle, it may bind to the particle in a method called crystallization.

The concentration units or structure are used to define the degree to which a solvent is soluble. A solution can be categorized as hydrophilic (water-loving), implying it has an electrostatic water-looking attraction, or hydrophobic (water-fearing), implying it repels water. A hydrophilic material is polar, and mostly includes groups of O–H or N–H that can shape water bonds.

my principles and I almost never do.  I'm going to violate my own personal
Prime Directive, and give you the answer without any explanation of where
it comes from.
