Your high-fidelity amplifier has one output for a speaker of resistance 8 Ω. How can you arrange two 8-Ω speakers, one 4-Ω speak

er, and one 12-Ω speaker so that the amplifier powers all speakers and their equivalent resistance when connected together in this way is 8 Ω? Compare the power output of your arrangement with the power output of a single 8-Ω speaker.

Answer:

(a) 8Ω (b)  Ratio = Parra/P8 ohm = 1

Explanation:

Solution

Recall that,

An high-fidelity amplifier has one output for a speaker of resistance of = 8 Ω

Now,

(a) How can  two 8-Ω speakers be  arranged, when one =  4-Ω speaker, and one =12-Ω speaker

The Upper arm is : 8 ohm, 8 ohm

The Lower arm is : 12 ohm, 4 ohm

The Requirement is  = (16 x 16)/(16 + 16) = 8 ohm

(b) compare  your arrangement  power output of with the power output of a single 8-Ω speaker

The Ratio = Parra/P8 ohm = 1

The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temp
natali 33 [55]

Answer:

Relative humidity %

Explanation:

  • The relative humidity is the percentage of the water vapor content at a particular temperature and pressure to the maximum amount of water vapor content the air can hold at those conditions.
  • When the relative humidity of the air becomes 100% then there occurs precipitation on the earth from the atmosphere (specifically troposphere, which accounts for the weather changes).
  • We might have experienced excessive sweating even on a relatively less hotter day of a summer which is on account of increased relative humidity.

The athlet at point A runs 150m east, then 70m west and then 100 east
denpristay [2]

Answer:

180m to the east

Explanation:

Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

  point A runs 150m east,

   70m west

  100m east

                                       150m

                --------------------------------------------------------→

                                                                   70m

                                                         ←---------------------

                                                                   100m

                                                         -----------------------------------→

The displacement of the athlete  = 150 - 80 + 100  = 180m to the east
