Answer #1

Polarimeter is an instrument used to determine the optical rotation of chemical molecules when plane polarised light will pass through a chemical molecule, the angle of rotation changes ie, it may rotate clockwise or anti clockwise direction. Molecules which rotate the plane polarised in a clockwise direction are called dextrorotatory and which rotate it towards anti-clockwise are called leavo rotatory.  Molecules which rotate the plane polarised in a clockwise direction are called dextrorotatory and which rotate it towards anti-clockwise are called leavo rotatory.

A car is traveling to the left, which is the negative direction. The direction of travel remains the same throughout this problem. The car's initial speed is 33.6 m/s, and during a 3.42 -second interval, it changes to a final speed of (a) 41.4 m/s and (b) 28.9 m/s. In each case, find the acceleration (magnitude and algebraic sign).
