Fire emits light and therefore brightens wherever the shadow would be depicted.
Answer:
H₂0_{(s)} + heat → H₂O(l)
Explanation:
An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.
On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.

Answer:
A.
Explanation:
The SUV accelerates uniformly. In this case, speed () is directly proportional to time (). That is:
(1)
Where is the proportionality constant.
Then, we eliminate this constant by creating the following relationship:
(2)
If we know that , and , then the time interval for the SUV to accelerate from rest to a speed is:
Hence, correct answer is A.
