Answer:
Physical sciences are those academic disciplines that aim to uncover the underlying laws of nature - often written in the language of mathematics. It is a collective term for areas of study including astronomy, chemistry, materials science and physics.
Explanation:
The statement 'a distant star gives off a visible range of light whose color depends on its temperature' is supported by the wave model.
<h3>What is wavelength?</h3>
The wavelength can be defined as the periodic distance of a given wave that repeats in a constant way.
The emissivity of particles is a function of both wavelength and temperature of a given material/object. Visible wavelengths range from 700 nm to 400 nm (violet color).
Star temperature largely determines its color, blue stars are warmer than yellow and red stars, and red stars are cooler than yellow stars.

<em>v</em> = 
= 27.7 km/h
Answer:
While In an <em><u>ideal/isolated</u></em> system, as long as the object is not in motion, its potential energy will be the same.
However, <u>potential energy is relative</u>. On Earth, usually, it is measured with respect to gravity. <u>The higher the object, the greater the potential gravitational energy</u>. It's all relative. For the sake of this question, I would assume that potential energy increases.
Explanation:
While kinetic energy depends upon speed, potential energy is always relative to some arbitrary reference point.
