Carol and juan were playing with carol's new train set. they pushed the trains around the track. they tried four different
sections of track. the train had the slowest speed on which section of track?

a) track 1
b) track 2
c) track 3
d) track 4

Speed (m/s) = distance (metres) ÷ time (seconds)

For Track 1: 0.2 ÷ 2 = 0.1m/s

For Track 2: 0.2 ÷ 2 = 0.1m/s

For Track 3: 0.6 ÷ 6 = 0.1m/s

For Track 4: 0.4 ÷ 6 = 0.07m/s

The train on Track 4 had the slowest speed because it's got the shortest speed and it's covering less distance per second therefore it is slower.

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.

i think that the answer is c
