Period = 2 seconds.
frequency = 1/2 cycle/second = 1/2 Hz
If it falls twice every four seconds, then it falls once every two seconds, therefore one falling period is two seconds.
Hz is equal to cycles per second. So if it goes through one cycle per two seconds, then it goes through 1/2 cycle per one second.
Hope this helps!
Answer:
Gravitational potential energy,Kinetic energy. when goes down potential goes into kinetic. Cant reach x because not enough potential energy
Explanation:
I’m guessing a coral reef becuase of all the different species of fish or a tropical rainforest if you look up what ecosystem contains the greatest species diversity you’ll find the answer :)
Answer:
120,000 J
Explanation:
The work done by a force applied parallel to an object is given by:
where
F is the magnitude of the force applied
d is the displacement of the object
In this problem:
F = 8000 N is the force exerted by the elevator to lift the passenger
d = 15 m is the displacement of the elevator
Therefore, the work done in this situation is
So, the work done is 120,000 J.
