(b)

Answer to Problem 41QP
The total mass lost by the comet since its early sighting is
Explanation of Solution
The every comet when comes near the sun, the comet action takes place and the body losses some of material as the action occurs.
The Halley’s Comet has appeared for
Write the expression for the mass lost by the comet during all its appearance.
Here,
Conclusion:
Substitute
Thus, the total mass lost by the comet since its early sighting is
