Pluto has mean diameter
of 2,300 km and very eccentric orbit (oval shaped) around the Sun, with
a perihelion (nearest) distance of 4.4 × 109 km and an aphelion
(farthest) distance of 7.3 × 109 km. What are the respective solid
angles subtended by Pluto from Earth’s perspective? Assume that distance
from the Sun can be neglected.

A weather forecasting plastic balloon of volume 15 m3 contains hydrogen of density 0.09 kg M-3. The volume of an equipment carried by the balloon is negligible compared to its own volume. The mass of empty balloon alone is 7.15 kg. The balloon is floating in air of density 1.3 kg M-3. Calculate : (i) the mass of hydrogen in the balloon, (ii) the mass of hydrogen and balloon, (iii) the total mass of hydrogen, balloon and equipment if the mass of equipment is x kg, (iv) the mass of air displaced by balloon and (v) the mass of equipment using the law of floatation.
