The velocity with which the group of waves travels is called as group velocity
or the velocity with which a ray packet goes is called as group velocity
Draw the v-t graph of an automobile that accelerates uniformly from rest at t = 0.00 s and covers a distance of 180.0 m in 12.0 s.
A certain machine exerts a force of 200 Newton on a box whose masses 30 kilograms. The machine moves the box a distance of 20 meters with a horizontal floor. What amount o
