AI Thread Summary
When a piece of copper weighing 220N is submerged in fresh water, the scale reading changes due to buoyancy. The buoyant force is calculated using the volume of the displaced water, which is derived from the copper's volume of 0.0025m^3 and the density of fresh water. The key forces involved are the weight of the copper and the buoyant force acting upward. The confusion arose from mixing units of volume and weight, but recognizing the gravitational acceleration of 9.8m/s^2 clarified the situation. Ultimately, understanding these forces leads to determining the new scale reading when the copper is submerged.

A scale reads 220N when a piece of copper is hanging from it. What does the scale read when it is lowered so the copper is submerged in fresh water.

From a given chart

Density:
copper is 8930 kg/m^3
fresh water is 1000kg/m^3

I found my volume of copper to be .0025m^3

I'm just not sure which direction to go now?

What forces are involved in buoyancy? Draw a free body diagram. Also write down the definition of buoyancy? Does anything click?
 
Since when was volume measured in Kg?
 
The forces involved are those from bottom and those on top of object. I have drawn the diagram and I think I know the connection I'm trying to make. The volume of the displaced fluid times density has to relate to the buoyant force? I think its the Newtons that's throwing me off

indeed my teach would've smacked me
 
geezzzz nevermind I got it. I thought i was looking over something simple.While obtaining the forces I was neglecting my 9.8m/s^2

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...
