Calculate the concentration of a sample which the wavelength reading is 60 and standard wave length reading is 80 with concentration of standard as 1 00mg/100ml using the standard concentration of 50 - 70mg/100ml 60 80mg/100ml 70 - 90mg/100ml 80 - 100mg/100ml

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?
