Answer:
Fe - Element
Fe2O3 - Compound
Explanation:
From the given chemical formula for two substances, Fe and Fe2O3, Fe is an element while fe2O3 is a compound.
It is so because an element is consist of the same type of atoms while a compund is consist of different atoms under specific proportions. for example: Fe is an element while fe2O3 is a compound.
Hence, the correct answer is:
Fe - Element
Fe2O3 - Compound
The total mass of the carts in the collision is the<u> independent variable</u> and the final velocity is a <u>dependent variable.</u>
- A variable that does not depend on another variable for its value is called an independent variable.
- Like the change in mass of cart will impact the momentum of the car but the mass will not get impacted by the change in the momentum.
- The variable which is tested or measured by conducting an experiment is called the dependent variable.
- The dependent variable value depends upon the independent variable.
- Like final velocity of the cart will get impacted after the collision as the mass of carts after collision will get reduced.
- A variable which constant throughout the course of an experiment is called the control variable.
So, from this, we can conclude that the total mass of the carts in the collision is the<u> independent variable</u> and the final velocity is a <u>dependent variable.</u>

Answer:
An asteroid is a minor planet of the inner Solar System. Historically, these terms have been applied to any astronomical object orbiting the Sun that did not resolve into a disc in a telescope and was not observed to have characteristics of an active comet such as a tail.
