The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet.
Answer:
C
Explanation:
Given that a liquid at rest in a fixed container exerts a force perpendicular to the wall of the container. Two students make claims about the microscopic cause of this force. Student A says that the force exerted by individual molecules as they bounce off the wall is always perpendicular to the wall. Student B says that the molecules may strike the wall at angles that are not perpendicular. Which student is correct and why?
The correct answer is option C
Student B . The molecules in a liquid are in random motion at the microscopic scale. For every atom that hits at an angle to one side of perpendicular, there is likely to be another atom hitting at the same speed at the same angle on the other side of perpendicular. On average the nonperpendicular components cancel
Here is the answer to the given question above. <span>The majority of supercell thunderstorms move to the right of the mean layer wind. This tendency is the result of differences in barometric pressure that develop as vertical wind shear interacts with the storm's updraft. In response to this vertical wind shear, an area of low pressure develops in the upper region of the down shear (right) side of the storm's updraft. In contrast, a region of relatively higher pressure forms on the other side of the updraft in the up shear portion of the storm. The region of low pressure on the right side of the updraft creates a favorable environment for propagation of the storm and, in response, it moves to the right.</span>
