Answer:
The reaction would be 1500n (equal reaction)
Explanation:
This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.
It doesn't matter whether one of the colliding bodies is of bigger mass than the other. This Newton's third law of motion is also known as the law of action and reaction.
Answer:
Postassium bisulphate - KHSO4 - can be used as an food preservative to protect the food from micro-organisms.
Answer: Option (A) is the correct answer.
Explanation:
When there occurs no change in the chemical composition of a substance then it is known as physical property.
For example, mass, volume, density are all physical properties.
Since, the mass of an electron is negligible and an electron holds a negative charge.
Therefore, negatively charged particle with very little mass accurately describes the physical properties of electrons in atoms.
