birth canal...

The manner in which the child passes through the birth canal in the second stage of labour depends upon the position in which it is lying and the shape of the mother’s pelvis. The sequence of events described in the following paragraphs is that which frequently occurs when the mother’s pelvis is of the usual type and the child is lying with the top of its head lowermost and transversely placed and the back of its head (OCCIPUT) directed toward the left side of the mother (see onset of labour in the figure). The top of the head, accordingly, is leading, and its long axis LIES transversely.

Further descent of the head directly downward in the direction in which it has been TRAVELING is opposed by the lower portion of the mother’s bony pelvis, behind, and the resisting soft parts that are interposed between it and the opening of the vagina (see internal rotation of head in the figure). Less resistance, on the other hand, is offered by the soft and dilatable walls of the lower birth canal, which is directed forward and upward. The back of the child’s head accordingly advances along the lower birth canal, distending its walls and dilating its cavity while the head progresses. Soon the back of the child’s neck becomes impinged against the bones of the pelvis, in front, and the chin is forced farther and farther away from the breastbone. Thus, as extension (bending of the head backward) takes the place of flexion, the occiput, brow, eye sockets, nose, mouth, and chin pass successively through the external opening of the lower birth canal and are born (see extension in the figure).

The neck, which was twisted during internal rotation of the head, untwists as soon as the head is born. Almost immediately after its birth, therefore, the top of the head is turned toward the left and backward.

As the child’s lower shoulder advances, it meets the sloping resistance of the pelvic floor on the right side and is shunted forward and to the left toward the middle of the pelvis in front. This position brings the long diameter of the shoulder circumference into relation with the anteroposterior, or long diameter, of the pelvic cavity. Because of this internal rotation of the shoulders, the top of the head undergoes further external rotation backward and to the left so that the child’s face comes to look directly at the inner aspect of the mother’s right thigh (see external rotation of head in the figure).

Soon after the shoulders rotate, the one in front appears in the vulvovaginal orifice and remains in this position while the other shoulder is swept forward by a lateral bending of the trunk through the same upward and forward curve that was followed by the head as it was being born. After this shoulder is delivered, the shoulder in front and the rest of the child’s body are expelled almost immediately and without any special mechanism.

An average of about one hour and 45 minutes is required for the completion of the second stage of labour in women who give birth for the first time. In subsequent labours the average duration of the stage of expulsion is somewhat shorter.

The diagram is as SHOWN in the figure. The direction of the current is from M to N. The direction of the magnetic field created due to this current carrying loop is also shown. The direction of the magnetic field is got by using Right Hand Thumb Rule at each point of the loop considering the direction of the electric current. This rule states that:

Imagine that you are holding a current-carrying straight conductor in your right hand such that the thumb points towards the direction of current. Then your fingers will wrap around the conductor in the direction of the field lines of the magnetic field.

The iron filings will be arranged in the direction of the magnetic field as shown.

The MAGNITUDE of magnetic field produced by a current carrying circular loop depends upon: The current passing through the circular loop-directly proportional. The radius of circular loop-inversely proportional. Number of turns of the wire in the circular loop-directly proportional.

As evident from the figure, the magnetic field lines will be less denser in the region near the circumference of the loop than at the center. Thus, the magnetic field will be stronger at the center of the loop than in the region near the circumference.

Answer:

Velocity is the rate of motion, or speed, in a specific direction. This means that velocity is a vector. We need both its magnitude, or value, and its direction. If we only know the speed, that is not the velocity. We have to also know the direction. If we just know were going 30 miles an hour, that is only our speed. If we know were going 30 miles an hour in a SOUTHWEST direction, then our velocity is 30 miles an hour southwest.

That is a vector. Average velocity is one of the two velocities that you need to keep in mind. Average velocity is found by dividing the distance traveled by the time traveled. Your formula would be velocity equals distance over time. You may start slow, speed up, and then slow down as you come to your destination. From point A to point B how FAR you traveled is going to be your distance. LET’s say you traveled 120 miles and you were traveling southwest.

It took you 60 minutes to get there. You would divide that. 120 divided by 60 equals 2. You were going two miles per minute southwest. That would be your velocity. Two miles per minute southwest. Now, if we were TRYING to do that in hours, we could have just CHANGED it to one hour. That would have been 120 miles per hour. That is really fast and not a likely velocity, but if something was going that fast, its velocity would be 120 miles per hour southwest or two miles per minute southwest.

What is ELECTROLYTE substance ?

Electrolytes are substances which, when dissolved in water, break up into cations (plus-charged ions) and anions (minus-charged ions).We say they ionize. Strong electrolytes ionize completely (100%), while weak electrolytes ionize only partially (usually on the ORDER of 1–10%).

Write the characteristics of electrolytes ?

It CONSISTS of solvent, dissociated positive and negative ions, or pure salt, i.e., a solvent-free IONIC liquid. The properties of an electrolyte depend on a number of parameters such as SIZE of the ion and concentration, conductivity, interaction between electrolyte, electrode materials, etc.
