Assertion :when fluid flows, there is some loss of energy due to friction.
Reason : Different layers of the fluid exert forces on each other .

Assertion : When two conductors charged to different potentials are conencted with a wire, there is always some loss of electric energy. Reason : A part of the electric energy is lost in the form of heat and electromagnetic radiation.

Liquids show viscosity which is due to X) Creation of friction between the layers of the fluid. Y) Inter molecular attraction forces of the liquid. Z) Inter molecular repulsion forces of the liquid.

Assertion : Damped vibrations indicate loss of energy Reason : The loss may be due to friction , air resistance ect

Assertion: If an object is submerged in fluid at rest, the fluid exerts a force on its surface. Reason: The force exerted by the fluid at rest has to be parallel to the surface in contact with it.

When a fluid is through a tube, then the reason of viscous force acting between its different layers will be

When a fluid is through a tube, thwn the reason of viscous force acting between its different layers will be

Assertion. When charges are shared between any two bodies, no charge is really lost but some loss of energy does occur. Reason. Some energy disappears in the from of heat, sparking etc.
