Atoms C6 13 O8 17 are related to each other as

Answer 1

Answer:

A car of mass 800kg is travelling with a velocity of 20 m/s. When brakes are applied,it stops after travelling a distance of 8 meters. Find Retardation and Retarding force? A force of 2N acting on a body changes its velocity uniformly from 2 m/s to 5 m/s in 10s. Calculate the mass of the body. Calculate the change in momentum of a body weighing 5kg when its velocity decreases from 20m/s to 5 m/s?(Hint: Calculate P2- P1) What would be force required to produce an acceleration of 2m/s2 on a body of mass 12kg? A ball freely falling from a tower of height 5 m . How much momentum does it transfer to the floor if its mass is 5kg?
