Elementary school children who separate and tend to play in groups of their own gender are demonstrating the ____ stage of psych

osexual development.

The answer is demonstrating the latency stage of psychosexual development. The latency stage which is 5 or 6 to puberty with no further psychosexual development takes place throughout this stage in which latent means are hidden. Freud alleged that maximum sexual instincts are inhibited for the duration of the latent stage and sexual energy can be transferred concerning school work, leisure pursuit and relationships.

Assume that the rod in Fig.31.2 has a length of 0.86 m,the resistor has value 2.2 ,and a magnetic field of 8.0 T is directed int
frutty [35]

1) 0.48 m/s

2) Clockwise

3) 10.3 N

Explanation:

1)

The figure is missing: find it in attachment.

As the rod is pulled along the rails, in the region of magnetic field, an electromotive force is induced in the rod itself, due to the change in magnetic flux through the circuit enclosed by the rod and the rails.

The magnitude of this induced electromotive force (which is equivalent to the potential difference induced in the rod) is

V=BvL

where:

B is the strength of the magnetic field

v is the speed of the rod

L is the length of the rod

Also we know that according to Ohm's law, the potential difference across the resistance is equal to

V=RI

where

R is the resistance of the rod

I is the current

Since the potential difference across the resistor is equal to the potential difference across the rod, we can combine the two equations, and we get:

BvL=RI\\v=\frac{RI}{BL}

Here we have:

R=2.2 \Omega\\B=8.0 T\\L=0.86 m\\I=1.5 A

Therefore, the speed of the rod must be:

v=\frac{(2.2)(1.5)}{(8.0)(0.86)}=0.48 m/s

2)

Here we have to apply Lenz's law, which states that the direction of the induced emf (and so, of the induced current) is such that it opposes the change in magnetic flux through the system.

First of all, here we notice that as the rod moves, the area enclosed by the circuit decreases: this means that the magnetic flux through the circuit decreases too.

As a result, the induced current must produce a magnetic field which goes in the same direction as the external field, in order to "restore" the magnetic flux. Here the external magnetic field points inside the paper, so the magnetic field produced by the induced current must also point inside the paper.

In order for that to happen, we see that the induced current must flow clockwise: in fact, if we take the rod and we apply the right-hand rule, we see that if we place the thumb towards the left (direction of the clockwise current), the other fingers "wrapped" point into the paper at the center of the circuit, so this is the correct direction.

3)

A current-carrying wire in a magnetic field experiences a force of magnitude

F=ILB

where

I is the current

L is the length of the wire

B is the strength of the magnetic field

Here we have

I = 1.5 A

L = 0.86 m

B = 8.0 T

So the force experienced by the rod is

F=(1.5)(8.0)(0.86)=10.3 N

Therefore, we must apply an equal and opposite force of 10.3 N in order to maintain keep the acceleration of the rod to zero, so that the velocity is constant, and the current is constant as well.

Which of the following is NOT a function of​ culture? A. Culture facilitates commitment to something larger than individual​ sel
kogti [31]

Answer:

B.

Explanation:

The term culture is derived from the Latin word 'colere' which means to '<u>tend, cultivate.'</u>

In sociology, the term refers to the shared values, beliefs, practices, and language of a society. These values and beliefs are learned from the past generation and passed on to the next generation by the present generation.

<u>A culture performs several functions in a society such as defining or creating boundaries between two distinct organization, it creates a sense of identity of the member of a particular organization, it also helps to stabilize the social system</u>.

From the given options, the option that does not define the function of a culture is option B. Thus the correct answer is option B.

Explain the human activities which are responsible for land degradation in India.
Nastasia [14]

Answer:

b. Human: Mining and industry.

Explanation:

Human activities such as mining, deforestation, over grazing and industrial activities etc are responsible for the land degradation in India. Due to mining, the land is disturbed and degraded when the minerals are extracted from the land. Cutting of trees leads to barren land and the wind and rainfall with high intensity removes the upper layer of the soil with the passage of time. Overgrazing of animals on the land removes all vegetation and the land is susceptible for erosion and degradation.
