No a Z doesn't have a rotational symmetry
A kite does not have rotational symmetry.
A trapezoid has no rotational symmetry.
Nothing has 1 order of rotational symmetry because in rotational symmetry 1 is none.
it has 5 rotational symmetry
They are in thermal equilibrium, not rotational equilibrium.
Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero. In rotational equilibrium, the sum of the torques is equal to zero. In other words, there is no net torque on the object.
which receptor is involved in the sense of rotational equilibrium
There is none
It is in equilibrium when the two conditions are satisfied - there is no net translational equilibrium and no net rotational equilibrium. For translational equilibrium, the summation of forces acting on the matter must equate to zero, which means that there is no resultant force. For rotational equilibrium, the sum of moments must be zero, which means there is no resultant torque. When these two conditions are met, the object will be stationary, i.e. it is in a state of equilibrium.
your rotational inertia will be zero
your rotational inertia will be zero
No. It's dynamic equilibrium
The object will be in both rotational and translational equilibrium and will not be moving.
heterogenous equilibrium is where there are different phases involved in the reaction.
Semicircular canals, filled with fluid, are involved in dynamic equilibrium. The tubes are oriented in three planes: horizontal, frontal, and sagittal. They respond to changes in the position of the head.
The first condition of equilibrium can be applied on concurrent forces that are equal in magnitude, since these produce translational equilibrium. But if the forces are equal in magnitude but are non concurrent then even first condition of equilibrium is satisfied but torque is produced which does not maintain rotational equilibrium. Hence for complete equilibrium that is, both translational and rotational , both the conditions should be satisfied.
