Unlike the ice cubes in a cold drink , dry ice doesn't melt to become liquid at all. Instead, at room temperature, it changes directly from a solid to a gas a process called sublimation . This expansion causes a rapid temperature drop, and some of the carbon dioxide freezes into solid pellets of dry ice.
Answer:
As the velocity of light is constant so the acceleration of the light is equal to zero.
a= dv/dt
Explanation:
The correct answer that would best complete the given statement above would be option B. PROTOSTAR. A large region of gas and dust that may contain as many as one million solar masses is called a protostar or star formation. Protostar is <span>a contracting mass of gas that represents an early stage in the formation of a star. Hope this helps.</span>
Is the most intensely studied celestial feature. It has also help revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. It is also the closest large star-forming region to Earth. The Orion Nebula is an enormous cloud of gas and dust, is located in our galaxy (Milky Way).
Answer:
the force decreases
Explanation:
Gravitational force is depending on it's mass and the distance between two object
The attachment shows us to understand relationship of it's
F ∝ 1/ (r)2
there for gravitational force is inversely proportional to it's distance . when distance between two object is increased, Then force will be decreased
