Question

Assertion-speed of a body can be negative.
Reason - If the body is moving in the opposite direction of positive motion, then its speed is
negative.
(a) A
(b). B
(c). C.
(d). D
Assertion-.if the displacement of the body is zero the distance covered by it may not be zero.
Reason-displacement is a vector quantity and distance is a scalar quantity.
Assertion-blood is a fluid connective tissue.
Reason- the plasma in the blood is mostly water.
Assertion-the inner mitochondrial membrane is highly folded.
Reason- to increase the surface area for ATP synthesis.
Assertion- a molecule of a compound has atoms of different elements.
Reason- a compound is a pure substance.​
