Answer:

Asteroids:

Explanation:

Asteroids are rocky, airless worlds that orbit our sun, but are too small to be called planets. Tens of thousands of these minor planets are gathered in the main asteroid belt, a vast doughnut-shaped ring between the orbits of Mars and Jupiter. Asteroids that pass close to Earth are called near-earth objects.

Convert the following dB to decimal a. -12 b. 3 c. 10 d. 0
stiks02 [169]

Answer:

for -12db

 \frac{V1}{V2}=0.251\\\\\frac{P1}{P2}=0.0631

for 3db

\frac{V1}{V2}=\sqrt{2}\\\\\frac{P1}{P2}=2

for 10db

\frac{V1}{V2}=3.16\\\\\frac{P1}{P2}=10

for 0db

\frac{V1}{V2}=1\\\\\frac{P1}{P2}=1

Explanation:

The decibel is a logaritmic value given by:

db=10*log(\frac{P1}{P2})=20*log(\frac{V1}{V2})

we use 10 for power values and 20 for other values such voltages or currents.

\frac{V1}{V2}=10^{\frac{db}{10}}\\\\\frac{P1}{P2}=10^{\frac{db}{20}}

for -12db

\frac{V1}{V2}=10^{\frac{-12}{10}}=0.251\\\\\frac{P1}{P2}=10^{\frac{-12}{20}}=0.0631

for 3db

\frac{V1}{V2}=10^{\frac{3}{10}}=\sqrt{2}\\\\\frac{P1}{P2}=10^{\frac{3}{20}}=2

for 10db

\frac{V1}{V2}=10^{\frac{10}{10}}=3.16\\\\\frac{P1}{P2}=10^{\frac{10}{20}}=10

for 0db

\frac{V1}{V2}=1\\\\\frac{P1}{P2}=1
