What is lightning rod how it protects the building? […]

What is the best motor to use for a wind generator? You should be looking for a motor with a minimum amperage rating of at least 5 Amps. Anything above 5 Amps and you are good to go. Remember, the more amps and volts the wind generator creates the more power it is producing! What […]

Are viruses alive Usatestprep answers? Once again, the scientific view changed: viruses may be complex biochemical particles but they are not alive. Viruses depend on the host cell for the raw materials and energy necessary for nucleic acid and protein synthesis, as well as all other biochemical activities that allow the virus to multiply and […]

What is an example of chemical weathering by water? Chemical Weathering From Water Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite. Feldspar crystals inside the granite react chemically, forming clay minerals. What are the […]
