A power-shift crawler tractor is excavating tough clay and pushing it a distance of 95 feet. Maximum reverse speeds are as follows: first range, 3 mph; second range, 5 mph; and third range, 8 mph. Rated blade capacity is 10 LCY. Estimate dozer production if the job efficiency factor is 0.83.Use Tables 1and 2.

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

a is the best answer your welcome
