There you go
Answer:
Your hypothesis is incorrect because warm substances rise when in a colder environment. The correct hypothesis would be : "If the 2 chambers of water are poured side by side, the warmer water will float above the cooler layer because warm water rises and cold water sinks."

100000000000000 I think):
Answer:
For a constant wavelength, Increase in frequency will increase in velocity of the wave. Example: For a constant wavelength, If frequency is doubled. The velocity of the wave will also double.
Explanation:
Explanation:
The minimum amount of energy required by a substance to begin a reaction is known as the activation energy.
Therefore, we can conclude that when you strike a match, you provide activation energy that enables the flame to appear.
Whereas a catalyst helps in increasing the rate of reaction but it does not start the reaction. On the other hand, when reactants combine together then we get products.
Thus, we can conclude that options (a), (b), (c), and (e) are not correct.
Hence, option (d) is the correct answer.
