... time it took to travel that certain distance would also be required. The independent variable is time and the dependant variable is ____________________. Hypothesis: coefficient of static friction on a rubber stopper and a wooden ramp is greater than the coefficient of static friction on a wooden ...
Identify data sources, gather and process information and use available evidence to assess the effects of sunspot activity on the Earth's power grid and satellite communications.
... visible features on the photosphere Sun; a moderate-sized sunspot is about as large as Earth. Sunspots form and dissipate over periods of days or weeks. They occur when strong magnetic fields emerge through the solar surface and allow the area to cool slightly, from a background value of ...
Hydroelectric Power
... of money and time to build. (USGA) Water turbines are used to spin a shaft which is attached to an alternator. The alternator is the heart of hydroelectric power plants . The alternator is the part that generates the electricity. There are two basic types of turbines, impulse and reaction. Impulse ...
