    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 '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 '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...
