  Area under v-t graph represents a physical quantity which has the unit (a)                                   (b) m                                     (c)                                    (d)

Answer:

  (b) Area under v-t graph represent displacement whose unit is metre or (m). Because, unit of velocity v = m/s and unit of time (T) = s.            Unit of (v-t) graph . Hence, the unit of (v-t) graph is metre (m).
