Answer:
(B) heated air in an uninsulated, unvented attic.
Explanation:
-Ice dams are formed by an interaction between snow cover, outside temperatures, and heat lost through the roof – more specifically, from heat loss through the poorly insulated ceiling of the house into the attic area and under the roof.
-Hot, humid air trapped in attics can also cause moisture to accumulate, resulting in mold or mildew.
Answer:
Using Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common-carrier frequency.
Explanation:
- In SSB modulators, we pre-process a real signal by Hilbert Transform filter to form another real signal
- The signal has the same spectral amplitude but has 90° phase shift at each frequency relative to its input signal.
- The ordered pair gets almost all of its negative components cancelled
- thus, with the use of Hilbert Transformation, we can transmit two independent base-band information signals by using SSB on a common carrier frequency.
Answer:
Each one should decide we is its formula is. Depending on what options one has in live. There is not a general formula for happiness and success. So there is not a general formula to change. Everyone must find its rigth formula.
