    Biological Explain
AI Thread Summary
A daughter can be biologically older than her parents through scenarios like the twin paradox, where time dilation affects aging differently for individuals. The discussion also touches on the forces acting on a robotic arm lifting a ball, emphasizing gravitational forces and the lifting force required. Participants suggest considering the effects of gravity on both the arm and the ball. The conversation highlights the complexity of these physics concepts and the challenges in understanding them. Overall, the thread seeks clarification on these intricate topics.

"Explain how a daughter can be biologicaly older then here parents"

" Draw a diagram of all the forces at work for a 10kg robotic arm to lift a 1kg ball.

Please Help Iv'e been staring at these questions for ever.

homework?

1: I guess the question is after the twin paradox

2: Think about it. The arm experiences the gravitiational force, the ball experiences the gravititational force and there's a force that lifts both the arm and the ball.
 

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
