state and explain the structure of ear?​

Answers

Answer:

The ear has external, middle, and inner portions. The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory canal, a short tube that ends at the eardrum (tympanic membrane).

The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bones—the malleus (hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.

Vector A has a magnitude of 27 m and
points in a direction 32° above the positive x axis. Vec-
tor B has a magnitude of 35 m and points in a direction
55° below the positive x axis. Sketch the vectors A, B,
and C = A + B. Estimate the magnitude and the
direction angle of from
your
sketch.

Answers

Answer:

The magnitude of the resultant is 55.0 m

The angle of resultant is 18.4°  below the x axis

Explanation:

Given that,

Magnitude of vector A = 27 m

Angle = 32° above the x axis

Magnitude of vector B = 35 m

Angle = 35° blow the x axis

We need to calculate the angle between the vectors

Using given angle

[tex]\theta=32-(-55)[/tex]

ptex]\theta=87^{\circ}[/tex]

We need to calculate the sum of vector A and B

Using formula of sum of vector

[tex]C=\sqrt{A^2+B^2+2AB\cos\theta}[/tex]

Put the value into the formula

[tex]C=\sqrt{27^2+35^2+2\times27\times35\cos87}[/tex]

[tex]C=55.0\ m[/tex]

We need to calculate the direction angle

Using formula of angle

[tex]\tan\theta=\dfrac{B\sin\theta}{A+B\cos\theta}[/tex]

Put the value into the formula

[tex]\tan\theta=\dfrac{35\sin87}{27+35\cos87}[/tex]

[tex]\tan\theta=1.21[/tex]

[tex]\theta=\tan^{-1}(1.21)[/tex]

[tex]\theta=50.4[/tex]

We need to calculate the angle of the resultant vector makes with vector A

Using formula of angle

[tex]\phi=32-50.4[/tex]

[tex]\phi=-18.4^{\circ}[/tex]

Negative sign shows that the direction of resultant is below the x axis

Hence, The magnitude of the resultant is 55.0 m

The angle of resultant is 18.4°  below the x axis

The magnitude of the sum of the vectors, C, can be obtained using the

parallelogram method.

The magnitude of the resultant vector, C, is approximately 45.3 meters.The direction of the resultant vector, C, is approximately 18.6° below the horizontal.

Reasons:

The given parameters are;

Magnitude of vector A = 27 m

The direction of vector A = 32° above the horizontal

Magnitude of vector B = 35 m

The direction of vector B = 55° above the horizontal

By drawing, using the parallelogram resolution of vectors on MS Word, and

taking extension of the resultant in the x and y-direction, we have;

C = A + B = 42.92·i - 14.48·j

The magnitude of the resultant vector is therefore;

|C| = √((42.92 m)² + (14.48 m)²) ≈ 45.3 m

The direction is given as follows;

[tex]\theta = arctan \left(-\dfrac{14.48}{42.92} \right) \approx -18.6^{\circ}[/tex]

Verifying, we get;

Vector A = 27×cos(32°)·i + 27×sin(32°)·j 22.9·i + 14.31·j

Vector B = 35×cos(-55°)·i + 35×sin(-55°)·j 20·08·i - 28.67·j

C = A + B = ( 22.9·i + 14.31·j) + (20·08·i - 28.67·j) = 42.98·i - 14.36·j

Therefore, the vector obtained by sketch is correct approximately.

The magnitude of the magnetic field is 0.01 m from the same wire will be 0.2 T.It is the type of domain where the magnetic force is received.

What is a magnetic field?

It is the type of field where the magnetic force is obtained. With the help of a magnetic field. The magnetic force is obtained it is the field felt around a moving electric charge.

The given data in the problem is;

r is the radius= 0.02 m

I is the current = 10,000A

x is the position considered = 0.002 m

The value of the electric current is found as;

[tex]\rm B= \frac{\mu_0 Ix }{2 \pi r} \\\\ \rm I= \frac{B \times 2\pi r}{\mu_0} \\\\ \rm I= \frac{0.1 \times 2\times 3.14 \times 0.02}{4 \pi \times 10^{-7}} \\\\ \rm I= 10,000 \ A[/tex]

The megnetic field through the wire will be;

[tex]\rm B= \frac{\mu_0 I}{2 \pi r} \\\\\rm B= \frac{4 \pi \times 10^{-7} \times 10,000}{2 \times 3.14 \times 0.01} \\\\ \rm B= 0.2 \ T[/tex]

Hence the value of the megnetic field will be 0.2 T.

A mountain climber has a mass (with all of their equipment) of 95, point, 0, k, g,95.0kg. If they were perfectly efficient, and ate 500, g,500g of chocolate (providing 11, point, 1, M, J,11.1MJ of chemical energy), how high could they climb?

Answers

Answer:

11900 meters

Explanation:

Use the Potential energy = mgh formula, substituting these in to get 11.1x10^6 = 95 x 9.81 x h.

Rearrange to make h the subject and the answer given is 11900 (3sig.fig.)

The maximum height to which he can climb will be 1.168 x 10⁴ meters.

What is potential energy?

The potential energy of a body is the energy of the body due it position. The potential energy always exist for two bodies which are in mutual interaction with each other for example by a force. For body a on earth, the potential energy of the body - earth system is -

E[P] = mgh

Given is a mountain climber that has a mass of 95 kg.

We can write -

Mass of climber = [M] = 95 kg

Energy gained by eating the chocolate = [E] = 11.1 MJ = 1.11 x 10⁷ joules

Assume that the height achieved achieve by the climber is [h] meters

Therefore, the potential energy gained at that height will be equal to 11 MJ

Therefore -

mgh = 1.11 x 10⁷

95 x 10 x h = 1.11 x 10⁷

95 x 10 x h = 1110 x 10⁴

h = (1110 x 10⁴)/950

h = 1.168 x 10⁴ meters

Therefore, the maximum height to which he can climb will be 1.168 x 10⁴ meters.

c) What are the centripetal accelerations of points A and B due to the spin of the
wheel? Sketch the situation and represent the vectors linear velocity and

Answers

(a) The angular velocity of the wheel is 31.42 rad/s.

(b) The linear speed of the wheel at point A is greater than point B.

(c) The centripetal accelerations of points A is 394.89 m/s² and point B is 197.44 m/s².

Angular velocity of the wheel

The angular velocity of the wheel is calculated as follows;

ω = 2π (5) = 31.42 rad/s

Linear speed of the wheel at point A

v = ωr

v = 31.42 x 0.4

v = 12.57 m/s

Linear speed of the wheel at point B

v = ωr

v = 31.42 x 0.2

v = 6.28 m/s

Thus, the linear speed of the wheel at point A is greater than point B.

Centripetal acceleration at point A

a = ω²r

a = (31.42)² x 0.4

a = 394.89 m/s²

Centripetal acceleration at point B

a = ω²r

a = (31.42)² x 0.2

a = 197.44 m/s²

A turtle moves at a speed of 1.0 km/h. How fast is the turtle
moving in meters per second (m/s)?

Answers

Answer:

0.28 m/s

Explanation:

1.0km/h * (1000m / 1km) * (1h / 3600s) =

The speed of the turtle in meters per second is 0.28.

What is unit conversion?

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. The speed is a scalar quantity and does not require any direction to represent it.

Given that the speed of the turtle is 1.0 km/h. The speed in meters per hour will be calculated as below:-

To calculate the speed in meters per second multiply the number by 1000 and divide it by 3600.

1.0 km/h. = 1 x 1000 / ( 3600 )

1.0 km/h. = 1000 / ( 3600 )

1.0 km/h. = 0.28 meter second.

Therefore, the speed of the turtle in meters per second is 0.28.

What determines whether something is solid or liquid or gas

Answers

Answer:

An object could be determined as solid:

-It doesn't change shape easily.

-when lots of heat applied till melting point, it would melt or thaw (basically turn into liquid).

-turn to pieces or bent when enough force applied to it.

-the molecules attached with each other by strong forces, creating strong bonds.

An object could be determined as liquid:

-It changes shaped based on the container.

-when lots of heat applied till boiling point, it would vaporize

-the molecules have weak bonds, creating a lot of spaces.

-when heat extracted from the liquid till freezing point, it would freeze/hardened (turn into solid)

An object could be determined as gas:

-it doesn't have any shape or form.

-if fills in the container.

-if lots of heat applied, its molecules are going to move, vibrate,and transist faster; increasing pressure and volume.

-The molecules have very weak bonds, creating spacious space.

-when the heat are being extracted till certain freezing point, it is going to turn into liquid, then solid.
