How long does it take solar energy to reach the earth if it travels at 300000 kms?

To answer this you need to know the average distance of the sun from the earth. This distance is 92,935,700 miles, or 149,565,511 Km. [1]
Using the classic distance = speed x time formula, we see that time = distance / speed.
149,565,511 Km / 300,000 Kms = 498.55 seconds, or 8.31 minutes.

What process is used when Thermal energy moving from the sun to earth?
The process used for the sun's heat energy to reach Earth is called thermal radiation. This electromagnetic radiation is caused by charged particles' motion in the Sun.
You place a hot glass rod in a cup filled with a cold liquid describe what will happen to the rod and the liquid with time?
They'll eventually reach the same temperature.
Where are potential and kinetic energy in a blizzard?
The kinetic energy would be the energy of a piece of snow hurtling through the air. The potential energy would be calculated based on how far the piece of snow has to go to reach the ground.
What is a term for no precipitation?
Virga is rain that does not reach the earth. Droughts are extended periods with no precipitation.
Which region of the electromagnetic spectrum can easily reach a telescope on the earth's surface?
Visible light.
Does most of suns energy reach earth in light energy?
it does reach the earth in light energy.
How does the energy of the sun's solar core eventually reach earth?
The energy travels through space in the form of electromagnetic radiation, which can be described as a plane wave motion or alternatively as a stream of photons.
How does the energy to reach Earth?
radiant energy
How does the sun produce energy and how is it transferred to the earth?
The sun produces energy via nuclear fusion. Electromagnetic energy in the form of light travels through the vacuum of space to reach earth via what we call radiation.
If light travles 300000 km s how long does light reflected from mars take to reach earth when mars is 65000000 km away?
It is 65000000/300000 = 216.6 seconds. That comes to be 3 minutes and 36.6 seconds.
What miles per second that the sunlight travels and how many minutes to reach the earth?
Light travels 186,282.4 miles per second in the vacuum of space. At that speed, it takes the light from the sun about 8 minutes and 18 seconds to reach Earth.
How long does it take for energy released by sun to reach earth?
That would depend on which type and form of energy you are referring to. Light energy takes about 8 minutes to reach Earth from the Sun.
What happen when an object travels faster?
It will reach its destination faster. It will also have more kinetic energy.
How does the energy of the sun reach earth and moon and other planets?
Radiation if that's the answer you're looking for... Radiation is the transfer of heat by electromagnetic waves (or light energy) traveling through space (but not outer space, just space like in the air).
How does the energy from an earth quake reach the surface of earth?
It travels through the ground.
How does the energy from an earthquake reach the surface earth?
in the form of body waves known as p (compressional waves) and s waves (shear waves). the energy of the earth quake also produces surface waves which have long amplitudes and short frequencies causing them to be extremely destructive
How long will it take the get the suns heat to earth?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy.
