What are two ways electromagnetic waves are used in a home computer scanner?
A. Red light shines on a black and white object, and light is reflected
according to the pattern of black and white

B. Visible light is reflected off an object and then captured by a
charge coupled device

C. An image is produced when a silicon chip releases electrons by
the photoelectric effect

D. X-rays shine on objects and the rays either pass through or are
absorbed by the objects

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

acceleration = 18/3 = 6 m/s per second.
