AI Thread Summary
The discussion centers on the sun's mass loss and its implications for future generations. The sun outputs approximately 4 x 10^26 Watts, leading to inquiries about how to calculate its mass loss per second. The equation E=mc^2 is identified as a key formula for understanding this relationship. There is uncertainty about whether the sun's power output will remain constant over time. Overall, the conversation highlights concerns about the sun's longevity and its impact on future life on Earth.

My friend told me that the sun is going to get smaller and smaller every year because it's getting used up? I've read that the power output is 4 x 10^26 Watts. How can i figure out how much mass it's losing a second? because then I will be able to find how long the sun will be able to shine on me and my children (hopefully).

thanks.

I don't really know how to attempt this problem because it's really random and i don't know any formulas for power.

merci.

nvm i think E=mc^2 will help me out thanks. wow I don't think my children will live to see the sun. sucks for them i am going to take lots of pictures i guess ..
 
1 watt = 1 joule per second

Mass is converted into energy through the equation

E = mc^2.

But is the power quoted going to remain constant throughout all the time t to be calculated?

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
