Answer:
If x = A sin w t where w is the angular frequency
then v = w A cos w t
Since KE = 1/2 m Vmax^2 and Vmax = w A maximum KE
the total energy is proportional to A^2
Also, since the maximum potential energy is
PEmax = 1/2 K A^2 where the KE is zero (maximum amplitude)
one can again see that the total energy is proportional to A^2
Answer:
the possible frequencies for the A string of the other violinist is 419 Hz
Explanation:
given information:
= 3 Hz
the frequency of the first violinist = 422 Hz
to find the possible frequency of the other violinist, we use the following equation':
= l - l
3 = l 422 - l
= 422 - 3
= 419 HZ
Answer:
1). Brake pedal or lever
2). A pushrod also called an actuating rod
Answer: acceleration = slope graph velocity vs time
Explanation: if you have the graph of velocity vs time , the slope of that graph equals the acceleration of our object assuming constant acceleration...but remenber por a real object is really hard to keep constant acceleration
I would say your answer to this question would be D
