A bar magnet is falling toward the center of a loop of wire, with the north pole oriented downwards. Viewed from the same side of the loop as the magnet, as the north pole approaches the loop, what is the direction of the induced current?.

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.

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.

Explanation:

(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.

The angular velocity of the wheel is calculated as follows;

ω = 2π (5) = 31.42 rad/s

v = ωr

v = 31.42 x 0.4

v = 12.57 m/s

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.

a = ω²r

a = (31.42)² x 0.4

a = 394.89 m/s²

a = ω²r

a = (31.42)² x 0.2

a = 197.44 m/s²

Explanation:

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.

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.

Explanation:

Atoms, molecules, and ions are the smallest particles that make up all matter. These microscopic particles are always in motion, either colliding or oscillating back and forth. Heat (or thermal) energy is created by the motion of particles and is found in all matter. As a result, thermal energy may be defined as an object's ability to perform work as a result of particle movement. Thermal energy is a form of kinetic energy, which is the energy associated with motion, because it is generated by the movement of particles.

Explanation:

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

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.

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 .

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.

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.
