Kinematics: jee advance

Derivation of kinetic energy in advanced strategy.

Can equation of Kinematics be used in a situation where the acceleration varies in time?Can they be used when acceleration is zero?

According to which phylogenetic system , dicots are advance with sympetalae conditions ?

Which condition is more advanced

Which one is the most advanced from evolutionary view point

Chorionic villus sampling technique is more advance than amniocentesis. Why?

What are different kinds of plastids? In the light of recent advancements describe the structure and function of chloroplast

Assertion : Kinematic equations are exact and are always correct. Reason : The definitions of instantaneous velocity and acceleration are true only for motion in which the magnitude and direction of acceleration are constant during the course of motion.
