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]

Answer:

Explanation:
Point B on a wheel of radius 40 cm that is rotating at a constant 5.0 revolutions
per second is located 0.20 m from the axis of rotation. Pont A is just at the border
of the wheel. See the figure.
a) What is the angular velocity of the wheel in rad/s?
b) What point has a greater linear speed, A or B? Calculate both speeds and
compare the results.
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
centripetal acceleration in points A and B. Assume the rotation of the wheel
to be clockwise.
(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 Av = ωr
v = 31.42 x 0.4
v = 12.57 m/s
Linear speed of the wheel at point Bv = 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 Aa = ω²r
a = (31.42)² x 0.4
a = 394.89 m/s²
Centripetal acceleration at point Ba = ω²r
a = (31.42)² x 0.2
a = 197.44 m/s²

state and explain the structure of ear?
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.
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.

i can predict the motion of objects based on newton’s laws because ________
Answer;
Newton's laws models the motion of a body perfectly well.
The knowledge of the force acting on a body gives a good grasp of the resulting motion.
There are three know laws of motion postulated by Newton;
1st law; it states that an object will remain in its state of rest or uniform motion unless if it is acted upon by an external force.
2nd law: it states that the acceleration of a body depends on the mass and force acting on it.
3rd law: it states that action and reaction are equal and opposite.
A sound understanding of these law's can help predict and model the motion of a body .

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