Which of the following is not true about compound microscopes and the dissecting microscope? select one: a. the compound microscope is used to observe thin slices of specimen while the dissecting microscope. does not necessarily need the samples to be thinly sliced in order to be viewed. b. the compound microscope has discrete powers of magnification while the dissecting microscope has a continuous range of magnification. c. the compound microscope has an inverted image whereas the dissecting microscope has the same orientation as the specimen. d. the highest magnification with the compound microscope can magnify to a higher power than a dissecting microscope during the histology lab. e. the compound microscope reflects light off the sample, whereas the dissecting microscope shines light through the sample.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
