Density Mass

AI Thread Summary

The asteroid Ida has a volume of 14,100 km³ and a satellite that orbits at a distance of 100 km with a period of 27 hours. To determine the mass of Ida, Kepler's 3rd Law can be applied, which relates the orbital period of a satellite to the mass of the primary body. The density of Ida can be calculated by dividing its mass by its volume. The satellite's size is noted to be 1.5 km wide. These calculations are essential for understanding the physical properties of asteroid Ida and its moon.

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...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
