Gain in decibels is a logarithmic base 2 scale with a multiplier of 3, so 3 db is twice the power, 6 db is four times, etc. Gain of -3.5 db means a power loss of 21.17, or a ratio of about -2.25. Note, however, that this is power, not voltage. Since power is voltage times amperes, and since amperes is voltage divided by resistance, in order to achieve a power loss of 2.25, the voltage must change by the square root of that, so the voltage changed by -1.5.

How do you determine the ratio of water to cement?
Concrete hardens as a result of the chemical reaction between cement and water so that for every 4 lbs of cement 1 lb of water is needed. The ratio is therefore 1:4 or 20%. This mix will be too dry so more water is needed than is technically necessary, the ratio should therefore be 35% to 40% and using a plasticizer
What should be the phase margin and gain margin For stability?
A very high gain margin or phase margin produces stable feedback systems, however they may be sluggish in operation. If the gain margin is close to unity of the phase margin is close to zero, the system will be highly oscillatory and produce overshoots with large amplitudes that take a while to settle. Having a gain of 6 dB or phase margin of 30 - 35 degrees will give you a relatively stable system. However there exists cases where this may not be so. :-)

What is the ratio for fly ash as the cement replacement in concrete?
Replacement of cement with flyash in concrete is 20-35 % by weight for normal structures. however for special structures like dams the replacement levelscan be increased to up to 70 %. (where flyash must be ISI standards compatible or any such standards) This replacement also reduces water requirement by 2.5 % for every 10 % replacement of flyash used.
How many seconds are there in 35 years?
2759400000--------------- original answer above is way too big, improved below -----------There are 36 possible answers,depends on how many leap years in those 35 years,starting the normal 35 years (no leap years):60 * 60 * 24 = 86400 seconds/day86400 * 365 * 35 = 1103760000 seconds / normal yearfor 1 leap years in those 35 : 1103760000 + 86400 = 1103846400for 2 : 1103760000 + 86400 * 2for 3 : 1103760000 + 86400 * 3...for 35 leap days: 1103760000 + 86400 * 35 = 1106764000so, the answer is between [1103760000,1106764000]
What is 56 Divided in the ratio 35?
56 divided in the ratio 35 = 1.6
Is the ratio 35 to 10 proportional to the ratio 7 to 5?
No - the ratio 35 to 10 is equivalent to the ratio 7 to 2 (not 7 to 5) because 7x5=35 and 2x5=10.
