Explanation:
Total displacement = 200 km
Total time taken = 2 hour...
Now...
= 100 kilometers/hour south
Decreases, stays the same, increases.
The volume decreases because as air is cooled, the individual molecules collectively possess less kinetic energy and the distances between them decrease, thus leading to a decrease in the volume they occupy at a certain pressure (please note that my answer only holds under constant pressure; air, as a gas, doesn't actually have a definite volume).
The mass stays the same because physical processes do not create or destroy matter. The law of conservation of mass is obeyed. You're only cooling the air, not adding more air molecules.
The density decreases because as the volume decreases and mass stays the same, you have the same mass occupying a smaller volume. Density is mass divided by volume, so as mass is held constant and volume decreases, density increases.
Bonds between atoms are formed
Answer:
It'd take approximately 6543 asteroids.
Explanation:
In order to calculate the number of asteroids needed to make that planet we first need to determine the volume of each object. To do this we will consider them as spheres and apply the appropriate formula:
The number of asteroids needed are given by the division of planet's volume by the asteroid's volume.
It'd take approximately 6543 asteroids.
