I calculated it several times and got the same answer, 40.38m/s, but the textbook says it's 28.6m/s.
Answer:
Explanation:
As the boy is riding from top to bottom of the hill his Potential energy gradually decreasing and simultaneously converting into the Kinetic energy.
At the top, his Potential Energy is maximum and kinetic energy is minimum i.e. zero
In the middle of the hill, he possesses both Potential and kinetic energy with equal magnitude.
At the bottom whole Potential energy is converted into Kinetic energy.
Thus Potential Energy is maximum at the top while Kinetic energy is maximum at the bottom.
Answer:
The candy before was fluffy, and the candy after was compacted.
Explanation:
The cloudy cotton candy was light and fluffy due to the air incorporated in it. After Chanel made it dense, the candy became compact and heavier, as she decreased the volume and maintained or increased the amount of sugar.
The cotton candy that Chanel had originally was described as being in a cloudy shape. This suggests that it was light, fluffy, and probably had a lot of air incorporated into it, which is why it was able to maintain such a shape. After she manipulated it to make it more dense, the cotton candy would have lost its cloudy appearance. Instead, it would have become heavier and more compact, because decreasing the amount of air in it increases its density. In other words, the volume of the cotton candy has decreased, but the amount of sugar within that volume has remained the same or increased.
