Proud dane.

With a bachelor in Mechanical Engineering and an on-going master in Sustainable Energy Engineering at The Technical University of Denmark, I'm just a sheep like everyone else.

A history of mud and push-ups in the Danish army as lieutenant and platoon leader.

Developing the thermoelectric product of my dreams is... my dream. Let's see what it brings.

comment Radioactivity, alpha decay
@BintEHawaGuijar I have attemptet to correct spelling and grammar in your question. Please check that it is still telling the story you want (and double-check the values, as another comment mentions.)

comment Zero velocity and non-zero average acceleration
From the reference system of the earth you are firm, with no velocity BUT there's the gravity acceleration This is incorrect, the net acceleration is zero. The gravitational acceleration is the acceleration that gravity would cause, yes, but only if nothing else prevents it.

comment Why does the water bottle not rotate when it is half full?
I believe the fluid inside moves around braking the motion. When it can't move, the rotation is equal to any other rigid system.

comment Cross product and the right hand rule - what is the intuition behind it?
@HolgerFiedler I understand your point, and agree most of the way. The torque "vector" is simply a convention made to fit the cross-product rule. But, another way to view it is, for the vectors $F$ and $r$ applied at a point, the torque will work around an axis, which certainly is perpendicular to both. This axis is pointed out by the cross-product, not by convention but by the nature of the mechanism. (The sign of that vector is then the only convention in this.)
