Explanation:
so branly delete every answer i give its weird but ok
Answer: The material that is not a mixture; it has the same properties all the way through is called a substance.
Explanation:
A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample. Hence, it cannot be separated by physical means. Example: Gold
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present. They can be separated by physical means as well. Example: Air
Thus the material that is not a mixture; it has the same properties all the way through is called a substance.
Answer:
a. sinusoidal wave
Explanation:
As we know that the medium particle will move in SHM when disturbance travel through the medium
Here the wave propagation through many ways are possible through the medium
When medium particles performs SHM then in that case the wave equation is given as
so we have above equation of wave must be sinusoidal equations
so correct answer will be
a. sinusoidal wave
