Solving the Problem: Lever & Metal Wedge in Water

AI Thread Summary
A submerged object in water generates an upward lift force of 100 kg, while a lever above it holds a 90 kg weight. The discussion centers on whether this weight difference is sufficient to move a metal wedge from point A to point D, given that the wedge is attached to a rope. The effectiveness of the movement is believed to depend on the force applied when pulling the rope. The mechanics of buoyancy and weight distribution are critical to solving this problem. Understanding these principles will determine if the wedge can be successfully moved.

hi..
i have a problem that i need to solve..
in the attached mage, there is a submerged object in water cousing na upward lift force of 100kg. above it is a lever with a weigh attached to it weighing at 90kg. wll this weight difference be enough to move the metal wedge from point a into point d, provided that the wedge is attached to a rope that will slide it along the yellow surface as it goes up out of the water.

I Think That It Would All Have To Do With How Hard Are You Pulling The Rope.
 
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...
