Mars is way closer than Uranus. Planets that are farther away from the Sun have longer orbits. For Uranus to go around the Sun, it takes around 84 Earth years. Mars completes its orbit around the Sun in about 1.8 Earth years.

Uranus takes longer than Mars to revolve around the sun because Uranus is further away from the sun than Mars so it won't travel as fast as Mars due to the distance.

A certain FM radio station broadcasts electromagnetic waves at a frequency of 60,500,000 Hz. These waves travel at a velocity of

dusya [7]

Answer:

Wavelength of radio wave = 4.96 meter (Approx.)

Explanation:

Given:

Frequency of radio wave = 60,500,000 Hz

Velocity of radio waves = 300,000,000 m/s

Find:

Wavelength of radio wave

Computation:

Wavelength = Velocity / frequency

Wavelength of radio wave = Velocity of radio waves / Frequency of radio wave

Wavelength of radio wave = 300,000,000 / 60,500,000

Wavelength of radio wave = 4.9586

Wavelength of radio wave = 4.96 meter (Approx.)

Two lamps rated 60W; 240V and 100W, 240Vrespectively are connected in series to a 240V power source. Calculate;

nikdorinn [45]

Answer:

See the answers below.

Explanation:

The total power of the circuit is equal to the sum of the powers of each lamp.

$P=60+100\\P=160 [W]$

Now we have a voltage source equal to 240 [V], so by means of the following equation we can find the current circulating in the circuit.

$P=V*I$

where:

P = power [W]

V = voltage [V]

I = current [amp]

$I = P/V\\I=160/240\\I=0.67 [amp]$

So this is the answer for c) I = 0.67 [amp]

We know that the voltage of each lamp is 240 [V]. Therefore using ohm's law which is equal to the product of resistance by current we can find the voltage of each lamp.

$V=I*R$
