If a 0. 10 m solution of a colored substance has a maximum absorbance at 500 nm and an absorbance of 0. 26 at its wavelength what will be the measured absorbance of a 0. 20 m solution at 500 nm.

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)
