Which of the following statements about Decision Trees is False? A decision tree uses Euclidian distance to split the data/create the decision rules. A decision tree algorithm does not have to use all the available attributes in the dataset when constructing the tree. In a decision tree, the algorithm can stop splitting a node (a partition) even if not all the observations in that node have the same outcome.

\[ \text { CAPS - Grade } 10 \] DBENovember 2016 QUESTION 5 (Start on a new page.) A woman is at the shopping mall \( 10 \mathrm{~m} \) above the grot \( \mathrm{c} \). Her cellphone, with a mass of \( 0,01 \mathrm{~kg} \), falls and hits the ground at a speed of \( 14 \cdot m \cdot \mathrm{s}^{-1} \). Ignore the effects of air resistance. 5.1 Convert \( 14 \mathrm{~m} \cdot \mathrm{s}^{-1} \) to \( \mathrm{km} \cdot \mathrm{h}^{-1} \). 5.2 Define the term kinetic energy. 5.3 Calculate the gravitational potential energy of the cellphone at a height of \( 5 \mathrm{~m} \) above the ground. 5.4 Calculate the velocity of the cellphone at a height of \( 5 \mathrm{~m} \) above the ground. 5.5 Will the value of the cellphone's mechanical energy just before it hits the ground be GREATER. THAN, LESS THAN or EQUAL TO the mechanical energy at a height of \( 5 \mathrm{~m} \) ? Explain the answer. (4) (3) [14
