5. Calculate: To find the total energy emitted in the proton-proton chain, you have to consider
the fact that two He-3 atoms must be created to form the final He-4 atom. Write the energy
produced in each step, and then find the sum of all of these energies using the table below.
Second step Last step
(He-3 created) (He-4 created)
Total energy
First He-3 atom
Second He-3 atom
First step
(H-2 created)
5.49MeV
1.44 Mev
Extend your thinking: To determine the net
equation for the conversion of hydrogen-1 to
helium-4. list the equations for each step of the
proton-proton chain in the space at right. (Write two
equations for the first step and the second step,
because these are repeated.)
Next, cross out any elements that appear on both
sides of the equation. Anything that remains makes
up the net equation.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

The path of a satellite orbiting the earth causes it to pass directly over two tracking stations a and b, which are 51 miles apart. when the satellite is on one side of the two stations, the angles of elevation at a and b are measured to be 87 degrees and 84 degrees, respectively. (a) how far is the satellite from station a? (b) how high is the satellite above the ground?
