Class 7 th Science Paper School Based Assessment 2024 I SBA First Term pape Explain why an atom is an electrically neutral particle and give one example. Model answer: The number of positively charged protons present in an atom is equal to the number of negatively charged electrons present there. It means that the total positive charge on an atom (due to protons) is equal to the total negative charge on it (due to electrons). The equal amounts of positive and negative charges cancel the effect of each other. An atom is therefore electrically neutral particle. Example: The neon atom is electrically neutral.

What is the distance between the \( (-5,0) \) and \( (0,2) \) ? Write answer as an exact answer no decimals and make sure to simplify if necessary.

\( \begin{array}{llll}\frac{2}{3} & \text { B) } \frac{3}{16} & \text { C) } 1 \frac{13}{16} & \text { D) } 1 \frac{1}{8} \\ 2010 \frac{2009}{2010} \cdot 2011 \frac{2009}{2010}-2009 \frac{2009}{2010} \cdot 2012 \frac{2009}{2010}\end{array} \)

How are the functions \( y=x \) and \( y=x-1 \) related? How are their graphs related? Each output for \( y=x-1 \) is 1 more than the corresponding output for \( y=x \). The graph of \( y=x-1 \) is the graph of \( y=x \) translated down 1 unit. Each output for \( y=x-1 \) is 1 less than the corresponding output for \( y=x \). The graph of \( y=x-1 \) is the graph of \( y=x \) translated up 1 unit. Each output for \( y=x-1 \) is 1 more than the corresponding output for \( y=x \). The graph of \( y=x-1 \) is the graph of \( y=x \) translated up 1 unit. The graphof \( y=x-1 \) is thegraphaf \( y-x \) t tuaplates doun 1 urit. Each output for \( y=x-1 \) is 1 less than the corresponding output for \( y=x \). The graph of \( y=x-1 \) is the graph of \( y=x \) translated down 1 unit.

Question 4 (1 print) Without graphing, identify the vertex, axis of symmetry, and transfiormations from the parent function fix \( =x x \) - \( y=|x-4|+6 \) The vertex is The axis of symmetry is \( x= \) What are the transformations from the parent function?
