Answer:
439 Hz
Explanation:
= Frequency of first wave = 440 Hz
F = Beat frequency = 1 Hz
= Frequency of the instrument
The beat frequency is the difference of the two waves which are interacting with each other
The frequency of the instrument is 439 Hz
Answer: 5 m/s^2
Explanation: In order to solve this question we have to use the kinematic equation given by:
Vf= Vo+a*t where V0 is zero.
we know that it takes Vf( 30 m/s) in 6 seconds
so
a=(30 m/s)/6 s= 5 m/s^2
Answer:
The bone marrow produces stem cells, the building blocks that the body uses to make the different blood cells. The erythropoietin sends a message to the stem cells telling more of them to develop into red blood cells.
