Yes because something that has been electrically charged can make other things move without touching them ( this is called force without contact)
Hoped this helped :)
In what language are you speaking?
Explanation:
It is given that,
Force applied to object, 
Position,
(b) The cross product of force and position vector is used to find the net torque about the z axis. It is given by :



or

The torque is acting in -z axis.
(a) The magnitude of torque is given by :


Hence, this is the required solution.
The main requirement for a good conductor of electricity is to have a lot of valence electrons. Valence electrons are the electrons of the outer shells of atoms not bound with other atoms (for example through covalent bounds). These electrons are "free to escape" as soon as an electric field with enough intensity is applied to the material, and therefore these electrons will be free to move in the material producing an electric current.
Answer:
a).
kJ/kg
b).
kJ/kg-K
Explanation:
a). The energy rate balance equation in the control volume is given by




kJ/kg
b). Entropy produced from the entropy balance equation in a control volume is given by





kJ/kg-K
