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

We found the centripetal acceleration of the earth as it revolves around the sun. compute the centripetal acceleration of a point on the surface of the earth at the equator caused by the rotation of the earth about its axis. (enter the magnitude. the radius of the earth is 6,371 km.)
