A fullerene is an allotrope of carbon in the form of a hollow sphere, ellipsoid, tube, and many other shapes. Spherical fullerenes, also referred to as Buckminsterfullerenes or buckyballs, resemble the balls used in association football. Cylindrical fullerenes are also called carbon nanotubes (buckytubes).
The answer is A. As a stable configuration is reached when atoms bond, so you are in a state of lower energy than not bonded.
Answer:
The skier will be moving at 13.31 m/s.
Explanation:
To calculate the velocity of the skier we need to find the acceleration, as follows:
![\Sigma F = ma](https://tex.z-dn.net/?f=%20%5CSigma%20F%20%3D%20ma%20)
Where:
: is the force due to the rope = 365 N
: is the combined average frictional force = 190 N
m: is the mass = 75.0 kg
![a = \frac{365 N - 190 N}{75.0 kg} = 2.33 m/s^{2}](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cfrac%7B365%20N%20-%20190%20N%7D%7B75.0%20kg%7D%20%3D%202.33%20m%2Fs%5E%7B2%7D%20)
Now, we can calculate the velocity of the skier by using the following kinematic equation:
![v_{f}^{2} = v_{0}^{2} + 2ad](https://tex.z-dn.net/?f=%20v_%7Bf%7D%5E%7B2%7D%20%3D%20v_%7B0%7D%5E%7B2%7D%20%2B%202ad%20)
Where:
: is the final velocity =?
: is the initial velocity = 0 (the skier is initially at rest)
d: is the distance = 38.0 m
![v_{f} = \sqrt{2*2.33 m/s^{2}*38.0 m} = 13.31 m/s](https://tex.z-dn.net/?f=%20v_%7Bf%7D%20%3D%20%5Csqrt%7B2%2A2.33%20m%2Fs%5E%7B2%7D%2A38.0%20m%7D%20%3D%2013.31%20m%2Fs%20)
Therefore, the skier will be moving at 13.31 m/s.
I hope it helps you!
Answer:
It's helps Emily became when she swims her hair is not in the way creating friction and making her swim faster. friction acts between two metals blocks that slide past each other.
Explanation:
Answer:
y < 272
Explanation:
first turn 1/8 into a decimal which is 0.125 then devide 34 by 0.125 which is 272, meaning y is less than 272
