AI Thread Summary
A 10-mile asteroid impact on deep oceans of large planets or moons could result in significant atmospheric effects, including the ejection of water vapor, which is a greenhouse gas that may lead to warming. The vast depths of these oceans might absorb much of the debris, potentially slowing the impact's effects. However, the collision would likely generate massive tsunamis along shorelines. The discussion highlights the differences between Earth's relatively dry conditions and the potential for much deeper oceans on other celestial bodies. Overall, such impacts could have profound environmental consequences.

Just curious what your thoughts are on ~10mile objects hitting deep oceans on large planets &/or Moons with very deep oceans? They say Earth is dry & that other planets & moons could have oceans 100's of KM's deep. Would there be any material being ejected into the atmosphere & blocking out the sun? As the vast water might soak up all the debris & slow the object? Would be some monster tsunamis on the shorelines.

Just curious.

I don't know about the Earth being dry but i would bet that an asteroid hitting an ocean would send a lot of water vapor into the atmosphere. Water vapor is a greenhouse gas so it may cause the planet to warm up some.
 

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...
