Answer:
The acceleration of Abbie is half of the Zak's.
Explanation:
The centripetal acceleration of an object on a circular path is given by :
Two children are riding on a merry-go-round that is rotating with a constant angular speed. Let 
is distance of Abbie from the merry-go-round and 
is distance of Zak's from the merry-go-round. Acceleration of Abbie is :
...... (1)
Acceleration of Zak's is :
.......(2)
Dividing equation (1) and (2) we get :
So, the acceleration of Abbie is half of the Zak's.
Horizontal speed = 24.0 m/s
height of the cliff = 51.0 m
For the initial vertical speed will are considering the vertical component. Therefore,
Since the student fires the canonical ball at the maximum height of 51 m, the initial vertical velocity will be zero. This means
let's find how long the ball remained in the air.

Finally, let's find the how far from the base of the building the ball landed(horizontal distance)
Answer:
when you bring two objects of different temperatures together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
The psychoanalytic perspective is built on foundation of
case studies as Sigmund Freud has base his theory with analysis of patients of
which we could point out that it has built with the foundation of case studies.
It is because case studies are the researches or study that is being reviewed
and are being analyzed in order to determine the causes of the problem and the
solutions of it.
Choice-A is a false statement, and the other three choices are absurdly untrue and physically impossible. None of the choices is an applicable response to the question.
