A car is traveling 50m/s N on the way home. There was an accident and the car slowed to 10m/s for 10secs What is the car's acceleration?

4m/s^2

Explanation:

Acc. = final velocity - initial velocity / time taken

= 50 - 10 / 10

= 40/10 = 4ms^2

the role of the microscope world in creating new materials .

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.
