a 60-w light bulb radiates electromagnetic waves uniformly in all directions. at a distance of 1.0 m from the bulb, the light in

tensity is i0, the average energy density of the waves is u0, and the rms electric and magnetic field values are e0 and b0, respectively.

LenKa [72]2 years ago
7 0

Answer:

Explanation:

1. If we increase the distance to twice it's original value, the light intensity is reduced by one-fourth, the light intensity would be:

I0/4

2. rms magnetic field is inversely proportional to distance, so the new rms magnetic field would be:

B0/2

3. average energy density is inversely proportional to the square of the distance, so the new average energy density is:

E0/4

Pluto would be placed 39.74 feet far from the Sun.

Astronomers use the gap between Earth and the sun, which is ninety-three million miles, as a new unit of measure called the Astronomical Unit.

Map scale refers to the connection (or ratio) between the space on a map and the corresponding distance on the ground. For example, on a 1:one hundred thousand scale map, 1cm at the map equals 1km on the ground.

The distance between the earth and solar, a = around 150 million km, is defined as one Astronomical Unit (AU). The radius of the solar, the solar is around 700,000 km.
