Explanation:
Detailed explanation-1: -the number of leaves is a scalar.. it only tells us how many there are. so it is a scalar. If the description described orientation or direction then it would be a vector.
Detailed explanation-2: -Mass is a scalar. Weight and mass are related to one another, but they are not the same quantity.
Detailed explanation-3: -Vectors: Weight, velocity, acceleration, force. Scalar: Mass, distance, time, volume, density, speed, temperature, energy.
Detailed explanation-4: -Mass, distance, time, and brightness are all scalar quantities.
