Answer:
hello your question is incomplete attached below is the missing part
answer : short period oscillations frequency = 0.063 rad / sec
phugoid oscillations natural frequency (
) = 4.27 rad/sec
Explanation:
first we have to state the general form of the equation
= 
where :


comparing the general form with the given equation
= 18.2329

hence the short period oscillation frequency (
) = 0.063 rad/sec
phugoid oscillations natural frequency (
) = 4.27 rad/sec
Erosion, weathering, mechanical changes, chemical changes.
Really, any interaction can change the composition of a rock whether it be done by man or through nature.
<span>Answer a. is correct. In this case the dog treats were positive reinforcers for staying close (the desirable behaviour). Repeated rewards for a certain behaviour work as positive reinforcers.</span>
