Nat2105 [25]

Answer:

D.400 watt

Explanation:

  • B/c <em>Pave</em><em>=</em><em>Irms</em><em>Vrms</em>
  • <em>Pave</em><em>=</em><em>(</em><em>5</em><em>)</em><em>(</em><em>8</em><em>0</em><em>)</em>
  • <em>Pave</em><em>=</em><em>4</em><em>0</em><em>0</em><em> </em><em>watt</em>

<em>where</em><em> </em><em>Pave</em><em> </em><em>=</em><em> </em><em>average</em><em> </em><em>power</em><em> </em>

<em>Irms</em><em>=</em><em>RMS</em><em> </em><em>current</em><em> </em><em>&</em>

___________ currents are most often used in the wiring of new buildings and homes, while _____________ currents are the type sto
yarga [219]

Answer:

Alternating; direct.

Explanation:

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

V = IR

Where;

V represents voltage measured in voltage.

I represents current measured in amperes.

R represents resistance measured in ohms.

Alternating currents are most often used in the wiring of new buildings and homes, while direct currents are the type stored in batteries and fuel cells.

Basically, the direction of an alternating current changes periodically.

The voyager 1 spacecraft is currently 20.7 billion km from earth and heading out of our solar system. how long does it take radi
sveta [45]

Answer:

20.7 billion = 20.7E9        converting to units of 10

20.7E9 km = 20.7E12 m

t = S /v = 20.7E12 m / 3.0E8 m/s = 6.9E4 s = 69000 s

69000 s = 1150 min = 19.2 hrs
