Whats the weight of the sunlight that hits the earth every year?
>>
Photons have no rest mass
>>
>>7754543
do plants absorb light and somehow make mass out of it? Sry for being a pleb.
>>
>>7754545
HOLY SHIT
>being this retarded

not sure if bait
>>
>>7754546
He isn't retarded for asking questions you faggot.

>>7754545
Plants don't gain mass from sunlight. They absorb light to gain the energy to turn carbondioxide into carbon (which they then use to build structures, so that's where the mass comes from) and oxygen (which mostly is a 'waste product' and excreted for animals to breathe).

Weight is a measure of force. Light from the sun does exert a force on the planet.

From some shitty simple calculation, with some hastily looked up numbers,
http://www.wolframalpha.com/input/?i=9.08e-6%20N%2Fm^2%20*%20pi*%28radius%20of%20earth%29^2&dataset=

The weight of the sunlight that hits the earth is about 1 billion newtons (200 million pounds.)

In photosynthesis, energy from photons is used to drive otherwise non-spontaneous chemical reactions forward. Specifically, it fixes carbon dioxide from the air (along with water) into sugars and oxygen gas. The mass of sugars produced during photosynthesis therefore comes from the atomic nuclei of CO2, but some of the sun's energy is now contained in the chemical bonds of sugars.

How much electricity is produced in a day by lightning in gigawatts?

They absorb light to gain the energy to turn carbondioxide into carbon (which they then use to build structures, so that's where the mass comes from) and oxygen (which mostly is a 'waste product' and excreted for animals to breathe).
and by that process, they convert energy into mass. Or rather they store energy in molecules which gives them more mass.

About three-fiddy

Why did I know I would get this response.
>>
>>7754554

Addendum: Mass cannot be created or destroyed, only transformed.

>>7754570
A lot

>>7755209
Hiroshima and Nagasaki disagree

e=mc2 says otherwise

Only applies to objects in rest. A photon can never be at rest.

Dumbass.

Light is waved particulates that impact and difuse. With the exception of your thought flow, any particulate , waved or otherwise, when impacting at the "speed of light" produces measurable force (Cartwaite, 1967).

With your kind of thinking, NASA won't pick you for a manned flight because you've obviously spent a lot of time already on Uranus.
>>
>>7756034
so he only thing that keeps earth from falling towards the sun is the light, pushing it away?

Why dont we get pushed into space?
>>
>>7756056
Woah. Trippy
>>
>>7756056
This would explain how black holes suck things in. They don't emit the light to "push" stuff away. Brilliant Anon. You deserve a Nobel Prize.
>>
>>7754565
This.

Photons hqve no weight, BUT we could do some interesting stuff.
If we take the total energy that reaches earth in a year because of photons..
We can use the relativity ecuation
E=mC^2
And taking in consideration that photons travel at C... We can just solve for the mass

>We can just solve for the mass
do it

what's the weight of dust that hits the earth every day? --> 60 tons a day. alrighty then, why is it important for the eath?
>>
>>7756350

Dust from the atmosphere? None, it's just regurgitation.

But photons exerting a force may have some significance because they could potentially effect the orbit of the earth. However since that force from the photons is obviosly constant then it's probably just another constant in the fixed forces that determine what path in the gravity well of the solar system earth does take.
>>
>>7756140
Can you even do that? I don't believe that's a valid conversion
>>
>>7756402
Cosmic dust from outer space.
>>
>>7756420

Whatever the weight is, it's effect I would wager are a yearly constant and are factored into the stability of the earth's orbit. All of these things add up and the only things that might change the math would be extremely large asteroids but even with those the numbers would average out over the centuries and millennia.
