Alveoli are tiny functioning structures that compose your lungs. They help with respiration. They have a large total surface area, which is very useful for respiration. The more surface area there is, the more transactions can happen. Which means that breathing will be easier/faster when you have more alveoli. (Please rate this answer if you have time!)

Hello!

Recall for resistors in parallel:
[tex]\frac{1}{R_t} = \frac{1}{R_1} + \frac{1}{R_2} + ... + \frac{1}{R_n}[/tex]

We can begin by calculating the total resistance:
[tex]\frac{1}{R_t} = \frac{1}{10} + \frac{1}{10} + \frac{1}{10}}\\\\\frac{1}{R_t} = \frac{3}{10}\\\\R_t = \frac{10}{3} = \boxed{3.333 \Omega}[/tex]

Now, we can calculate the current using Ohm's Law:
[tex]V = iR\\\\i = \frac{V}{R}[/tex]

V = Voltage of battery (V)
i = Current (A)

R = Resistance (Ω)

Plug in the given voltage and the total resistance we solved for.

[tex]i = \frac{15}{3.33} = \boxed{4.5 A}[/tex]

For a mass m1 on the frictionless table, the speed m1 must rotate a with radius r if m2 is to remain hanging at rest is mathematically given as

In a circuit, if the resistors were decreased by a factor of 1,000, it is true that the current would increase by a factor of 1,000, according to Ohm's Law.

It is a law in electricity that posits that the voltage that goes through a conductor is directly proportional to the current.

One formula in Ohm's law is:

Voltage = Current x Resistance

If the resistance were to decrease by a factor of 1,000, the current would have to increase by a factor of 1,000 as well in order to give the same voltage.

Explanation:

[tex]$$The focal length is: \\ \\ \begin{aligned}f &=\frac{R}{2} \\&=-\frac{46}{2} \\f &=-20 \mathrm{~cm}\end{aligned}$$[/tex]

[tex]$$ Since the image is virtual: \\ \\ :\begin{aligned}\frac{v}{u} &=m \\\Rightarrow & v=m u \\\Rightarrow &v=2 u\end{aligned}$$[/tex]

[tex]$$ Using: \\ \\ \begin{aligned}&\frac{1}{l}=\frac{1}{v}+\frac{1}{u} \\&\frac{1}{20}=-\frac{1}{2 u}+\frac{1}{u} \\&\frac{1}{2 u}=\frac{1}{-20} \\&\Rightarrow u=-10 \\&\therefore u=10 \mathrm{~cm}\end{aligned}$$[/tex]

(a) The impulse on the puck is 1.323 kgm/s.

(b) The magnitude of the force that acted on the puck is 264.5 N.

The impulse on the puck is equal to the change in momentum of the puck.

The change in th momentum of the puck is calculated as follows;

ΔP = m(u - v)

where;

Magnitude of the final velocity

|v| = √[(-25)² + (5)²] = 25.5 m/s

ΔP = 0.115(37 - 25.5)

ΔP = 1.323 kgm/s

Thus, the impulse on the puck is 1.323 kgm/s.

The magnitude of the force that acted on the puck is calculated as follows;

The electron energy does not depend on the focusing cylinder voltage because the magnetic field runs perpendicular to the electron's direction of movement.

A magnetic field is produced by moving negatively electric charges (electrons) which generate magnetic forces that are observable.

The negative electrons that orbit around atoms in a molecule generate small magnetic fields around such atoms.

According to Fleming's left-hand rule, the direction of a magnetic force acting on a current is perpendicular to the direction of the electric current and magnetic field.

Because it exerts a force that's also parallel to the horizontal fields instead of in opposition to it, the final electron energy is unchanged by the focusing cylinder voltage.

An electron's energy is on the same scale (in the same range) as that of light. The lines in an element's spectrum represent changes in the energy of electrons within the element's atoms. Scientists have reached numerous conclusions regarding the behavior of electrons in atoms by studying these spectra.

Negative electrons orbiting around atoms in a molecule produce modest magnetic fields surrounding them.

The vector of a magnetic force that acts on a current is opposite to the axis of the electric current and magnetic fields, as per Fleming's left-hand rule.

Thus, because it exerts a force that's also parallel to the horizontal fields instead of in opposition to it, the final electron energy is unchanged by the focusing cylinder voltage.

D, A convex lens converges light and curves outward.

Explanation:

edge

A convex lens converges light and curves outward.

A lens that is thin at the bottom and upper edges and somewhat thick in the middle is referred to as a convex lens. The edges are not bent inside, but rather outward.

Here,

In a convex lens, the light rays travelling parallel to its principal axis are converged by it (i.e., the incident rays are directed towards the principal axis).

Since all of the light rays that are refracted by a convex lens eventually converge at a single point, where the image is created, the convex lens is also known as a converging lens.

A converging lens produced a virtual image when the object is placed in front of the focal point.

Hence,

The centripetal force of the rock tied to a string and swung in a circular path is determined as 1.65 N.

The angular speed of the rock is calculated as follows;

ω = 2π N

[tex]\omega = 35^0 \times \frac{2 \pi \ rad}{360^0} \times \frac{100}{3\min} \times \frac{1 \min}{60 \ s} \\\\\omega = 0.339 \ rad/s[/tex]

The centripetal force of the rock is calculated from the product of mass and centripetal acceleration as shown below;

Fc = ma

Fc = m(ω²r)

Fc = mω²r

Fc = 8 x (0.339)² x 1.8

(a) The wavelength of the resonance created is 0.8 m.

(b) The speed of the sound in the fundamental mode is 400 m/s.

(c) The low value of speed of speed of sound in water calculated may be as a result of low temperature of the water poured into the cooking pot.

The wavelength of the resonance created is determined by assuming the cooking pot to be a closed pipe.

Wavelength of fundamental mode of a closed pile = 4L

where;

λ = 4 x 0.2 = 0.8 m

The speed of the sound in the fundamental mode is calculated as follows;

v = fλ

v = 500 x 0.8

v = 400 m/s

Sound wave is directly proportional to temperture, as the temperature of the water increases, the speed of sound increases as well.

(A+BCosθ)=0

Cosθ=-A/B ----(2)

Using equation (1)

B/2 = √(A²+B²+2ABcosθ)

B/2=√(A²+B²-2A²)

B/2=√(B²-A²)

B²/4=B²-A²

A²=B²-B²/4

A²=3B²/4

A=√3B/2

Cosθ=-A/B

Cosθ=-[√3B/2]/B

Cosθ=-√3/2

Answer:

Weight of the body in air = 20gf ( Wa)

Weight of the body in water = 18gf ( Ws)

Weight of the body in liquid =18.2gf ( Wl)

Now,

The loss of weight in the water = 20 - 18 or, 2 gf

So the relative density of the body is = Wa / ( wa - ws )

= 20 / 2

= 10

2) The weight loss in liquid = 20 - 18.2 or, 1.8 gf

So the relative density of the liquid is =( Wa - Wl ) / ( Wa - Ws )
