Post multiple queries in different thread. The answer to question no 1 is below,. scalar quantity is an physical quantity which has magnitude but no direction. examples of scalar: temperature( temp. has magnitude but it cant be expressed in an direction), time( time can be measured in second or hours but cant be given an direction as in 20 minutes south ) on the other hand vector quantities are those which have magnitude as well as direction . for e.g. a car moving with a speed of 20 km/hr east
