(i) 15 kg is a scalar quantity because it involves only mass.
(ii) 20 kg weight is vector quantity as it involves both magnitude and direction.
(iii) 45° is a scalar quantity as it involves only magnitude.
(iv) 10 meters south-east is a vector quantity as it involves direction.
(v) 50 m/s2 is a scalar quantity as it involves magnitude of acceleration.
