Answer:
Kinetic energy.
The explanation never existed
The answer is 13.5 because 27÷3.0=13.5
Answer:
<em>Pure water </em><em>won’t conduct electricity</em>
<em>Option A</em>
Explanation:
Pure water doesn’t contain salts or impurities. It is the salts that dissociate to form ions that act as charge carriers in conducting solutions. For a medium to conduct electricity it should have carriers to carry the electrical charge.
Thus absence of charge carriers make pure water non conducting. Charge carriers in metals are electrons and in ionic solutions they are positive and negative ions.
Tap water, aquarium water and ocean water contains dissolved electrolytes. When electricity is passed through them the electrolytes dissociates into ions and these ions conduct electricity.
Answer: Option (d) is the correct answer.
Explanation:
Dalton's model of atom states that every matter is made up of atoms and these atoms are indivisible in nature.
On the other hand, Thomson's model of atom states that there are small particles present in an atom that has positive or negative charges.
Thomson's model of atom is also known as plum pudding model where negatively charged particles are represented by plum and positively charged particles are represented by pudding.
Thus, we can conclude that Thomson’s model of the atom include smaller particles that Dalton’s model did not have.
Answer:
True
Explanation:
It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion. Any change in motion involves an acceleration, and then Newton's Second Law applies.
