Answer:
Both objects are moving.
Explanation:
Object 1 is moving because the unbalanced force acting on the skateboard is causing it to <em>either move slower or move faster.</em> An example of this is when the skateboard is going down the hill. The unbalanced force is caused by the gravity which speeds up the skateboard.
Object 2 is also moving although it has a balance force; however, it is moving at a<em> "constant speed."</em> This is because the force of thrusting forward is being counteracted by a friction force of the <u>same magnitude.</u> Forces that are equal in magnitude and of opposing directions causing the speed to be constant. So, the bicycle is still moving.
Answer:
The primary type of energy change which occurs by turning on the phone will be the conversion of the stored chemical energy of the battery into electrical energy. The chemical energy is also converted into light energy, sound energy and heat energy. With the passage of time, the energy will be changed back into the chemical energy when we will charge the phone again.
<span>A river can only carry a load if it has adequate energy. When the energy drops below a certain level, therefore, the load is dropped. In the Thalweg (the line of fastest flow), more load is carried, and this is also where the erosion occurs, adding more load. On the inside of a meander, for example, since the Thalweg is on the outside, the velocity on the inside is very low, and so deposition occurs. On the very inside, water merely trickles past. This is incapable of transporting load, so it deposits it until it is able to carry all of it.</span>
Answer:
Decomposition reaction
Explanation:
Chemical equation:
2KClO₃ → 2KCl + 3O₂
The given reaction is decomposition reaction.
Decomposition reaction:
It is the reaction in which one reactant is break down into two or more product.
AB → A + B
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
Single replacement:
It is the reaction in which one elements replace the other element in compound.
AB + C → AC + B
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
