Answer:
Wavelength of sound waves millimetres
Explanation:
The speed of any wave is equal to the product of its wavelength and frequency.
This can be represented mathematically as
Where
V is the speed of sound waves
f is the frequency of sound waves
and
is the wavelength of the sound waves.
Substituting the given values in above equation we get -
meters
millimetres
Answer:
No
Explanation:
It is not correct to say that an object with the largest volume has the largest mass.
Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.
Mass is the amount of matter in a substance. Volume is the space a body occupies.
- A balloon and a stone for example is a typical one.
- A balloon has more volume but far lesser mass compared to a stone.
- A stone, gravel sized has low volume but more massive than a balloon.
Therefore, it is wrong to say a balloon has more mass because it has more volume.
To change only one variable which is very important than to test the experiment to match the hypothesis again, I think. It’s been a while since I was on that lesson♀️
