It is true because <span>Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through heat transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases. Thus, the molecules begin moving more and usually maintain a greater average separation.</span>
<h2>Answer: Jupiter and Saturn have compositions that are fairly different from the compositions of Uranus and Neptune.</h2>
Jovian Planets (means "similar to Jupiter") is the name given to the "gaseous giant" planets of our solar system. Although they share many similarities, they have certain differences.
For example, Jupiter and Saturn are classified as "gas giants", while Uranus and Neptune are "ice giants".
This is also due to the fact that Uranus and Neptune have higher concentrations of <u>methane</u> (hence its bluish color) and some heavier elements such as oxygen, carbon, nitrogen, and sulfur. On the other hand, Jupiter and Saturn tend to be orange-white in appearance due to the mixture of <u>hydrogen</u> that gives off a red aspect.
Answer:
B
Explanation:
Acceleration = rate of change in velocity
a = (21-12)/(0.45) = 20cm/s^2
Yes I do think so because it is not a star, and it is not an astroid or meteor. Do it MUST be a planet.
