The mark of the beginning of the representational thought is
when children are likely to be able to internalize images in terms of their own
sensorimotor activities, this way, this will mark the beginning of a representational
thought that has already occurred.
Answer.
The relationship between a college student and their classroom is important in teaching. If the relationship between them is not good then it may have serious impact in the way of success in a course.
If a student have problem with professor then he should first contact the professor and discuss about it, most of the instructors and students try to solve such issues. If a problem cannot be worked out then the student should contact the department or the division chairperson. If nothing works then the student should talk to the dean.
The correct answer is A) The space shuttle program has come to an end.
The author thinks that the time may now be right to focus on ocean research because the space shuttle program has come to an end.
The main argument for the author to support ocean exploration is that he considered that the space shuttle program of NASA had already ended in 2011. Too much money -billions of dollars- had been invested in the space program, and now it was time to enter the unknown territories of the oceans.
The author is probably right. We do not much about oceans and what could be under the sea. That is a real mystery. We have explored enough about the space, according to our possibilities and limitations, but practically the ocean is unknown. So ocean exploration would be a real challenge.

Arrow A represents the direction of the electric field vector at the position of the dot.
A dot indicates the location of an electric charge at a certain location. The electric field line will radiate outward in the case of a positive charge. If the charge is negative, the electric field will radiate outward from it. The direction of the electric field at a certain location is not, however, shown by the dot. As a result, reading the values of negative signs on a field line is useless.
As compared to the negative charge, the positive charge, Q, is twice as distant from the dot. We must first measure the intensity of the electric fields in order to determine the electrical field at a certain location. The positive charge is represented by +Q in Figure Q20.5, whereas the negative charge is represented by -1. The intensity of the electric field at a spot represented by a dot must thus be equal to the total of the electric fields pointing in that direction.
