What is a magnetic dipole?

When considering the idea of a magnetic dipole, it involves having two magnetic poles that possess equal strength but differ in polarity. This particular configuration results in the creation of a magnetic field that flows from the north to south pole. The magnitude of this field is determined by the size of the magnetic dipole moment, which serves as a distinctive quality of the magnet.

Which is an accurate statement about a magnetic field's direction?

The idea of a magnetic field pertains to a specific region in space that can exert magnetic force on either a magnet or a charged particle in motion. The orientation of the magnetic field lines indicates the direction of the force that would affect any magnetic object within the field. It's important to note that these lines always form closed loops, originating from the north pole of the magnet and extending through surrounding space before ultimately returning to enter at its south pole. This implies that without fail, magnetic field lines travel from north to south pole, with this directional flow being reliant on the magnet's magnetic dipole moment.

The following are dimensions of various physical parameters that will be discussed later on in the text. Here [L], [T], and [M] denote, respectively, dimensions of length, time, and mass.

Dimension Dimension
Distance (x) [L] Acceleration (a) [L]/[T]2
Time (t) [T] Force (F) [M][L]/[T]2
Mass (m) [M] Energy (E) [M][L]2/[T]2
Speed (v) [L]/[T]

Which of the following equations are dimensionally correct?

a. F = ma
b. x = 2 at2
c. E = 1/2 max
d. E = max
e. F = ?Fx/m

Answers

Dimentional analysis is very important in physics, because it allows finding errors in equations. We find that the following true equations

a) F= m a

b) x = 2 a t²

c) E = [tex]\frac{1}{2} }\ m \ a \ x[/tex]

d) E = m a x

The fundamental units in mechanics are;

the length [L] whose unit is the meter

The time [T] that has the second as a unit

The mass [M] with fundamental unit the kilogram (kg)

all other quantities are derived from these three fundamental units, for example velocity is

     v = x / t

we replace the units

     [v] = [L] / [T]

so the units of velocity are the distance between time.

This exercise uses the units of various quantities and asks to find if the equations are dimensionally correct.

Let's substitute the units in each expression

a) F = m a

    [M] [L] / [[T] ² = [M] [L] / [T] ²

the two sides of the expression are equal therefore the equation is correct

b) x = 2 a t²

scalar quantities have no units

    [L] = [L] / [T] ² [T] ²

    [L] = [L]

the two sides are equal, therefore the equation is correct

c) E = ½ m a x

    [M] [L] ² [T] ² = [M] [L] [T] ² [L]

    [M] [L] ² [T] ² = [M] [L] ² [T] ²

the two sides are equal the equation is correct

d) E = m a x

since scalar quantities have no units, this expression is equivalent to the expression in part c, therefore it is correct

e) F = F x / m

    [M] [L] / [T] ² = [M] [L] / [T] ² [L] / [M]

    [M] [L] / [T] ² = [L] ² / [T] ²

the two sides are different so the equation is false

In the dimensional analysis we find that expressions are true a, b, c, d  and we see that the expression e is false

The diagram below represents the forces acting upon a rightward-moving object.
Each arrow represents a force; the length of the arrow represents the strength of
the force.

Answers

Answer:

Explanation:

The up and down arrows appear to me to be of the same length, therefore there is no up or down acceleration.

There are no right or left arrows, therefore there is no right or left acceleration.

The mass moves with constant velocity.

This could be the free body diagram of an ice puck sliding across a frictionless ice surface.

The down arrow is the puck weight. The up arrow is the normal force of the ice on the puck.

A friction force would be represented by a horizontal arrow to the left for the rightward moving mass. It's not there.

If something were increasing the rightward speed, like a bottle rocket attached to the puck, it would be represented as a right facing arrow.

A train started its journey at 9:00. Its average speed between
9:00 and 13:00 was 80 km/h. It travelled 1/5 of its journey by
13:00. If the train was required to arrive at the destination at
21:00, what average speed must the train travel at for the rest
of the journey?

Answers

Answer:

Explanation:

In the four hours before 13:00 the train traveled 4(80) = 320 km.

It needs to travel another 4(320) = 1280 km in the next 21:00 - 13:00 = 8 hrs.

1280 / 8 = 160 km/hr

We can define average speed as:

s = (distance traveled)/(time it takes)

Using this, we will find that the average speed at which the train must travel the rest of the journey is 160km/h.

Here the given information is:

The train starts its journey at 9:00

The average speed between 9:00 and 13:00 was 80km/h, and it travels 1/5 of the journey by 13:00.

Then, if we define D as the total distance of the whole journey, in that lapse of 4 hours the train traveled 1/5 of D, or just D/5.

Then we can write the average speed as:

[tex]80km/h = \frac{(D/5)}{4h}[/tex]

[tex]80km/h*4h = D/5[/tex]

[tex]320km = D/5[/tex]

[tex]5*320km = D = 1,600km[/tex]

This means that the total distance of the journey is 1,600km

And at this time (13:00) the train already traveled 320km, so the distance left is:

[tex]d = 1,600km - 320km = 1,280km[/tex]

And we know that the train needs to finish the journey at 21:00

The time between 13:00 and 21:00 is 8 hours.

So the train needs to travel a distance of 1,280km in 8 hours, then the average speed that the train needs is:

[tex]s = (1,280km)/8h = 160 km/h[/tex]

s = 160km/h

The Kinetic Molecular Theory (KMT) is discussed in this lesson, and it helps us understand the behavior of gases. From what we learned, which of these statements are consistent with KMT?
A. Due to the large amount of empty space between gas molecules/atoms, the density of a gas is very low.
B. Gas molecules are in constant, random motion, so they take the shape and volume of whatever container they are in.
C. Since atoms are mostly empty space, gases can be compressed.
D. Gas molecules/atoms collide with each other and surfaces without losing energy. E. All of the above statements are consistent with KMT.

Answers

Answer:

Explanation:

for a.;

Kinetic molecular theory assumes the collision of particles with each other and walls of container as perfectly elastic, that is why no particle loses energy.

for b.;

Kinetic molecular theory assumes that particles are of very small size incomparison with the size of container and far apart from each other that is why their density is very low. because density is described as

Density = Mass/Volume

So, one can imagine that in a big container, entire mass of all gas particles is very low as compared to the volume of container. So the gas have very low density

For c.;

Gases assume shape of their container because they are freely moving with in a container

For d.;

For statement in "b", one can easily understand that because according to kinetic molecular theory, particles are very small and at great distances, so they are compressible against any external pressure applied

3) La normal es una línea perpendicular a la línea que divide las dos medias.

En óptica es habitual describir los fenómenos con respecto a una línea perpendicular al plano de incidencia de la onda electromagnética, esta línea se denomina Normal.
