Answer:
<h2>The answer is 2500 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration is given by
<h3>Force = mass × acceleration</h3>
From the question
mass of car = 25 kg
acceleration = 100 m/s²
The force is
Force = 25 × 100
We have the final answer as
<h3>2500 N</h3>

Answer:
What do you think causes some rock types to have higher densities than others? (Assuming there are no air pockets in the rock, the types of minerals will determine the density.

Answer:
Both the identity and the properties of a substance change.
Explanation:
During most chemical reactions, both the identity and the properties of substances changes. The chemical and physical properties of a substance often changes during this kind reaction.
A chemical change has the following properties:
- A new kind of substance forms.
- It is always accompanied by energy changes
- Involves a change in mass of the substance
- Considerable amount of energy is involved in this reaction.
- The process is irreversible
