Caesium-134 has a half life of 2.06 years. Use the half life equation to approximate how long it will take for a
500 g sample of caesium-134 to decay to 1 g.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.

i think its d if wrong im sorry
