(a)
Find the amount of energy would be released when all the mass of deuterium in ocean are fused to
(a)
Answer to Problem 27P
The amount of energy that would be released when all the mass of deuterium in ocean are fused to
Explanation of Solution
The volume of the oceans is
Write the formula for power
Write the formula for energy released
Write the formula for energy
Write the formula for mass
Where, E is the total energy converted,
Conclusion:
Converting miles into meter: Volume of the oceans if
Substitute
The mass of the water molecule in ocean is
To find the mass of hydrogen in ocean,
The mass of hydrogen in ocean is
As
The mass of deuterium in ocean is
Substitute
The number of deuterium nuclei in the ocean is
Since, all the mass of deuterium in ocean are fused to
Substitute
The energy released per fusion reaction is
Substitute
Thus, the amount of energy that would be released when all the mass of deuterium in ocean are fused to
(b)
How many years would the energy calculated in part (a) last.
(b)
Answer to Problem 27P
The energy calculated in part (a) would last for
Explanation of Solution
The world power consumption is
Write the formula for power
Where, E is the total energy converted,
Conclusion:
Substitute
Thus, the energy calculated in part (a) would last for

- 13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets?
