1. LINE GRAPHS: Line graphs are used when we compare two different number values. 1.1. Draw two graphs on the same set of axes showing the changes in heart rate of two boys. Jor and Thabo, as they run over a certain distance. 70 Distance run (m) John's heart rate Thabc's heart rate (beats per minute) (beats per minute) 0 60 100 75 80 200 85 90 400 100 110 800 120 1500 115 120 130

where is the following

explanation:

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
