Which of the following is not included in ptolemy's model of the solar system?
a. epicycles
b. eccentrics
c. eccentric epicycles
d. nested spheres
eventually philosophers decided that the lowest point in the cosmos was the center of the cosmos and that everything was attracted to that point. but, denser objects push lighter ones out of the way. what phenomenon did this not explain?
a. the earth is a sphere.
b. the earth and the things on it are layered.
c. there are volcanoes some places on earth but not in others.
d. the oceans sit on the earth without falling over the edge.

1.  c. eccentric epicycles

2. d. The oceans sit on the Earth without falling over the edge.

Explanation:

1.

In Ptolemaic model is used to study the apparent motion of planets in direct way ,  by assuming that each and every planet moves on a small sphere or circle , known as the epicycle . And each planet is moved by a system of two spheres one is epicylce and other is different , the center of different circle is called eccentrics . Nested spheres are also present in the Ptolemy's model.

2.

The oceans sit on the Earth without falling over the edge is the correct answer. If all the heavy density objects are pushing lighter objects away then the Earth itself would have thrown away the oceans out of its reach.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
