A boy and his dogs are running, The white dog has a mass of 10 kg The black dog has a mass of 20 kg. The boy has a mass of 40 kg They are all running at 3 m/s Kinetic Energy Versus Mass 1. Evaluate Expressions Determine the kinetic energy of the dogs and the boy. Record the kinetic energy for each. 250 200 150 2. Construct Graphs Graph the data to show how mass and kinetic energy are related 3. SEP Use Mathematics Suppose the smaller dog speeds up to 6 m/s. What is the kinetic energy of the dog now? How is kinetic energy related to speed? Kinetic energy (J) 100 50 0 0 10 40 50 20 30 Mass (kg)

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.      

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
