In order for a thermonuclear fusion reaction of two deuterons (GH*) to take place, the deuterons must collide and each must have a velocity of about 1 x 10°m/s. Find the wavelength of such a deuteron.

2. The data in the table show the amount of a 500 g sample of sodium-24 over time. Time (h) Na-24 (g) Time (h) Na-24 (g) 0 500 55 397 60 315 65 250 70 198 75 5 10 15 20 25 30 35 40 45 50 158 125 99 79 63 50 80 85 90 95 100 39 31 25 20 16 12 10 8 6 5 Make a graph of the data (remember to label all axes and title the graph). What is the half-life of sodium-24? Explain how you determined your answer. Sodium-24 decays by beta emission. Write a nuclear equation that shows the decay of sodium-24 and its products.

Chemistry - $2 - MI / Electromagnetic Radiation / Lesson 173 1. What is the frequency of a wave? O how many times a wave is repeated during a certain interval of time O the amount of time it takes from one crest or trough to travel one second the time it takes to pass by another object O the length of the wave from crest to crest or from trough to trough
