Plutonium-240 decays according to the function \[q(t)=q _{o}e ^{-kt}\] where q represents the quantity remaining after t years and k is the decay constant, 0.00011.. how long will it take 36 grams of plutonium-240 to decay to 12 grams? . a. 18,900 years. b. 1.44 years. c. 9,990 years. d. 2,100 years.

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.
