AI Thread Summary

The Earth is approximately 1.494 x 10^11 meters from the sun, which is equivalent to 149.6 million kilometers. Light from the sun takes about 8.3 minutes to reach Earth, translating to 498 seconds. The calculation involves multiplying the speed of light, 3 x 10^8 m/s, by the time in seconds. The discussion confirms the accuracy of this calculation. Overall, the distance from the Earth to the sun is a straightforward computation based on the speed of light.

@Beanie it's absolutely correct. An easy question, these patterns are just difficult if you mess up the calculation part.

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Power of a thin lens in a medium is 1/fₘ or μₘ/fₘ ?'

Here is what I tried This question was actually asked in one of our engineering entrances. The answer was 1D. My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.

Thread 'Voltmeter readings for this circuit with switches'

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...
