Answer: An object undergoing uniform circular motion is moving
Explanation:
Answer:
129.74 Hz
Explanation:
Given:
Wave velocity ( v ) = 346 m / sec
wavelength ( λ ) = 2.69 m
We have to calculate Frequency ( f ) :
We know:
v = λ / t [ f = 1 / t ]
v = λ f
= > f = v / λ
Putting values here we get:
= > f = 346 / 2.69 Hz
= > f = 34600 / 269 Hz
= > f = 129.74 Hz
Hence, frequency of sound is 129.74 Hz.
Answer:
A.
Explanation:
momentum depends on weight and speed
Well I can't see the following physical properties you talked about in the question.
Mass per unit volume ratio is called density.
I think it would be the scientific method.
