Bubble of water in zero gravity

AI Thread Summary
In zero gravity, a bubble of water would maintain its shape due to surface tension, allowing it to hold together. Fish inside the bubble could potentially swim outside and suffocate, raising questions about their ability to return to the water. The discussion also speculates on whether a dolphin, capable of breathing air, could adapt to swimming through air in a zero-gravity environment. The dynamics of water and air in space present intriguing challenges for aquatic life. Overall, the conversation highlights the unique interactions between physics and biology in outer space.

What if you were in a spaceship in outer space and had a sphere filled with water and some fish in it and then carefully removed the shell, leaving behind only a bubble of water. Would the water hold together and could the fish would swim outside the bubble and suffocate?

Yes, because of surface tension. You can find videos of this.

This could happen. An interesting question would be, if it can swim back to the water through the air. Or if a dolphin, which can breathe air, would learn to swim through air in zero-g.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
