Irrotational,rotational,solenoidal vecter field
a heart have no rotational symmetry!
It has rotational symmetry to the order of 2
A regular nonagon with 9 sides has a rotational symmetry of 9.
Yes, a crescent has a rotational symmetry.
Rotational symmetry of order 1.
Irrotational fields are conservative, simply connected (path independent), and have no curl (del cross the field) = 0Rotational fields are orthogonal MTM=I, symmetrical, representable in any finite dimension through orthogonal matrix multiplication
Zero
No, for example (-yi +xj)/(x^2 + y^2) is irrotational but not conservative on the domain {(x,y}|x^2 + y^2 > 0}.
Because farming certain plants drains certain nutrients from the soil. Rotational farming rotates the crops being grown (sometimes fields are left fallow i.e. empty) and therefore, nutrients remain in the soil.
Torque is developed by, among other things as well, the magnetic attraction or repulsion of two magnetic fields, contributing through rotational leverage to produce a net torque.
The magnetic fields are not aligned with the rotational axis of the planet and they are not located at the center of the planet.
