The type microscope used to visualize the positions of individual atoms.

Answer to Problem 4RQ
The microscope that allows us to visualize the positions of individual atoms is the scanning probe microscope.
Explanation of Solution
An atom is so small that it could not be seen even through a microscope. This is because the visible light passes right them. An individual light is smaller than the
However, with the advancement of technology, it is now possible to generate images of them indirectly. Through a scanning probe microscope, images are produced by dragging an ultrathin needle back and forth over the surface of a sample. Interactions with the surface atoms are detected and translated by a computer into three-dimensional images that correspond to the positions of atoms on the surface.
Conclusion:
Therefore, microscope that allows us to visualize the positions of individual atoms is the scanning probe microscope.

- Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.
