Answer:
Top: PE = max, KE = 0
Middle: PE = half, KE = half
Bottom: PE = 0, KE = max
Explanation:
The potential energy of an object is the energy possessed by the object due to its location; it is given by
where
m is the mass of the object
g is the acceleration due to gravity
h is the height of the object from the ground
The kinetic energy of an object is the energy possessed by the object due to its motion; it is given by
where
v is the speed of the object
Now we analyze the three situations for the boy on the bycicle:
Top of the hill: here h (the height) is maximum, so the potential energy is maximum, while the speed is zero, therefore the kinetic energy is zero.
Middle of the hill: here h (the height) is half of the initial value, therefore the potential energy is also half of the initial potential energy. According to the law of conservation of energy, the total mechanical energy (potential+kinetic) is constant: this means that also the kinetic energy is half of the initial potential energy.
Bottom of the hill: here h is zero, therefore the potential energy is now zero. As a result, all the mechanical energy has been converted into kinetic energy, therefore the kinetic energy is maximum and it is equal to the potential energy of the boy when he was at the top.
Regional metamorphism is a type of metamorphism in which the minerals and the textures of the rocks are changed or altered due to the effect of pressure and heat over a wide area or region.
This type of metamorphism often results in metamorphic rocks that are strongly foliated.
Metamorphism usually occurs in the folds of thrust mountain belts.
Answer: You would most likely find regional metamorphism associated with a mountain belt.
Given what we know, the statement in this question can be considered as true, since Syncopation does in fact shift the beat off of regular rhythms.
<h3>What is Syncopation?</h3>
- This is when regular beats are offset in order to disrupt the melody.
- This is done purposefully.
- It causes the listener a need to continue in order to hear the beat return to normal.
Therefore, given that Syncopation is defined as a shift or displacement in the rhythms or beats from something <em><u>strong and normal</u></em> to something that causes the listener to want the beat to go back to normal.

Your question: An objects momentum is determined by the object's..?
Your answer: An objects momentum is determined by the object's mass and velocity.
Happy Studying! =)
Answer:
Force due to tension
Explanation:
Usually Ft, or F
, denotes force due to tension or tension force. An example of tension force would be if you were pulling an object on a string - the tension force is present within the string and causes the string not to break.
