AI Thread Summary
The weight of the crown and the solid gold piece is the same in air. When submerged in water, the apparent weight of a crown made of gold and silver will be less than that of the solid gold due to the lower density of silver, which affects buoyancy. Conversely, if the crown is made of gold and platinum, which has a higher density than gold, the apparent weight in water will be greater than that of the solid gold. This is because the buoyant force acting on the crown will be less than that on the solid gold piece due to its higher density. Understanding buoyant forces is crucial to analyzing the differences in apparent weight.

The weight in the air of the crown and the piece of solid gold is the same

1) If the crown is made of gold and silver (density is less than that of the gold) is the apparent weight of the crown in water greater than, equal to, or less than that of the solid gold? Why?

2) What if the crown is made of gold and platinum, which has the higher density than gold?

Well, what do you know about buoyant forces?
 
Not much :/

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...
