Question

The planet Venus can never reach which planetary configuration when viewed from Earth?

opposition superior conjunction inferior conjunction greatest elongation The strength of gravity on Mars is about 40% of that on Earth. If you were to take a standard red brick to Mars, which property of the brick would be significantly different on Mars than on Earth? mass color volume weight The reason Copernicus' heliocentric theory soon came to be regarded as preferable to the geocentric theory of Ptolemy is that the heliocentric theory accounted for the observed motions of the planets using complex constructions called epicycles and deferents, so it was considered more reliable than the geocentric theory. the same observed motions of the planets as the geocentric theory but did so in a much simpler way. retrograde motion, which the geocentric theory was unable to explain. the same observed motions of the planets as the geocentric theory but did so much more accurately. which one plz hurry

Answer 1

(a)

Answer: opposition

The planet Venus can never reach   planetary configuration when viewed from Earth is opposition.

(b) Answer : weight

Mass is amount of matter contains in the objects. It is an independent quantity. It does not depend on the gravity. That means it does not vary from place to place.

Therefore, the mass is same either on earth or on Mars.

The weight is gravitaional pull acting on pbjects. The gravity is different from one planet to other.Therefore, we observe significant change in weight.

accounted for the same observed motions of the planets as the geocentric theory but did so in a much simpler way.
