Answer:
How does energy travel?
One way the energy can travel is through radiation. An object can radiate energy in the form of electromagnetic waves, for example when a strong light is turned on and you can feel some heat coming from it, or when you walk under the sunlight and you can feel the heat in your skin.
Where is the initial source of energy in our solar system?
In the solar system, the source of energy comes from the Sun, and the sun irradiates that energy to all the nearby objects.
What is the process that gives off energy from the sun called?
The process is called radiation, this is all the energy that comes from the sun in the form of different electromagnetic waves (light in the visible range, UV rays, etc...)
If u divide the number you'll get on an average of 20km
Answer:
Option D.) 0.09 I₀
Explanation:
The intensity, I, of a polarized light after passing through a polarizing filter is given by 
Original Intensity
Angle between the direction of polarization and the axis of filter
After passing through the first polarizer, the initial intensity, 
is halved, i.e 
After passing through the second polarizer, the angle of polarization, θ = 30⁰
After passing through the third polarizer, the angle of polarization, θ = 90⁰-30⁰ = 60⁰
