Answer:

D. It sends electrical impulses to the brain.

Explanation:

<u>Cochlea is a part of the inner ear that is shaped like a snail. . it is a sense organ that translates sound into nerve impulses that is in turn sent to the brain.</u>
A human being has two cochlea one in each ear. They transform the vibrations of the cochlear liquids and associated structures into neural signal.
In other words the cochlea transfers the pressure waves of the sound into nerve impulses, that are then taken by the brain for interpretation.

dusya [7]

Answer:

300 nm

Explanation:

R = Gas constant = 8.314 J/molK

r = Atomic radii = $1\times 10^{-10}\ m$

d = Atomic diameter = $2r=2\times 10^{-10}\ m$

At STP

T = Temperature = 273.15 K

P = Pressure = 100 kPa

$N_A$ = Avogadro's number = $6.022\times 10^{23}$

The mean free path is given by

$\lambda=\frac{RT}{\sqrt2d^2N_AP}\\\Rightarrow \lambda=\frac{8.314\times 273.15}{\sqrt2 \pi \times (2\times 10^{-10})^2\times 6.022\times 10^{23}\times 100000}\\\Rightarrow \lambda=2.12165\times 10^{-7}\ m=212.165\times 10^{-9}\ m=212.165\ nm$

The answer that best represents the mean free path for gas molecules is 300 nm

A cyclotron is designed to accelerate protons (mass 1.67 x 10^-27 kg) up to a kinetic energy of 2.5 x 10^-13 J. If the magnetic

Dafna11 [192]

Answer:

24 cm

Explanation:

Given:

Mass of proton = 1.67 × 10⁻²⁷ Kg

kinetic energy = 2.5 × 10⁻¹³ J

magnetic field in the cyclotron, B = 0.75 T

Now,

Kinetic energy = $\frac{1}{2}mv^2$ = 2.5 × 10⁻¹³ J

where, v is the velocity of the electron

$\frac{1}{2}\times1.67\times10^{-27}\times v^2$ = 2.5 × 10⁻¹³ J

v² = 2.99 × 10¹⁴

v = 1.73 × 10⁷ m/s

also,

centripetal force = magnetic force

$\frac{mv^2}{r}$ = qvB

q is the charge of the electron

r is the radius of the dipole magnets

on substituting the respective values, we get

$\frac{1.67\times10^{-27}\times1.73\times10^7}{r}$ = 1.6 × 10⁻¹⁹ × 0.75

r = 0.2408 m ≈ 24 cm

Hence, the correct answer is 24 cm

A person tosses a ball from the ground up into the air at an initial speed of 10 m/sec and an initial angle of 43° off the groun

Artemon [7]

<h2>Component of the velocity of the ball in the horizontal direction just before the ball hits the ground = 7.31 m/s</h2>

Explanation:

In horizontal direction there is acceleration or deceleration for a ball tossed upward at an initial angle of 43° off the ground.

So the horizontal component of velocity always remains the same.

Horizontal component of velocity is the cosine component of velocity.

Initial velocity, u = 10 m/s

Angle, θ = 43°

Horizontal component of velocity = u cosθ

Horizontal component of velocity = 10 cos43

Horizontal component of velocity = 7.31 m/s

Since the horizontal velocity is unaffected, we have

Component of the velocity of the ball in the horizontal direction just before the ball hits the ground = 7.31 m/s
