First row: Quality of light, Phosphors have a narrow frequency range in comparison to a high spectrum incandescent. Adding phosphors to help the light quality adds cost and loss of efficiency. Second row: Size, C F L's are larger than their incandescent counterparts. They may not fit in the existing light fixtures. Third row: Electronics, Using C F L's with a dimmer can short the shelf life. Fourth row: Heat, Higher luminosity C F L's can get warm. They should not be run with the electronics (ballast) above the tube. Therefore, they cannot be used for pendant or recessed lights. What is the purpose of this table?
a.
To explain the benefits of a CFL
c.
To explain the benefits of an incandescent bulb.
b.
To outline the higher costs of an incandescent bulb.
d.
to explain the drawbacks of a CFL

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
