Explanation:
Amphipathic molecules are the molecules that consists of both polar and non-polar parts.
For example, fats and oils are amphipathic molecules.
Amphipathic molecules have two different parts. One is water loving which is also known as hydrophilic side and other is water fearing which is also known as hydrophobic side.
Molecules that are amphipathic must contain both hydrophilic and hydrophobic regions or parts.
Answer:
![Force = 0.0047175\ N](https://tex.z-dn.net/?f=Force%20%3D%200.0047175%5C%20N)
Explanation:
Given
--- Surface Tension
--- Radius
Required
Determine the required force
First, we calculate the circumference (C) of the circular plate
![C= 2\pi r](https://tex.z-dn.net/?f=C%3D%202%5Cpi%20r)
![C= 2 * \frac{22}{7} * 0.01m](https://tex.z-dn.net/?f=C%3D%202%20%2A%20%5Cfrac%7B22%7D%7B7%7D%20%2A%200.01m)
![C= \frac{2 * 22 * 0.01}{7}m](https://tex.z-dn.net/?f=C%3D%20%5Cfrac%7B2%20%2A%2022%20%2A%200.01%7D%7B7%7Dm)
![C= \frac{0.44}{7}m](https://tex.z-dn.net/?f=C%3D%20%5Cfrac%7B0.44%7D%7B7%7Dm)
![C= 0.0629 m](https://tex.z-dn.net/?f=C%3D%200.0629%20m)
The applied force is then calculated using;
![Force = C * T](https://tex.z-dn.net/?f=Force%20%3D%20C%20%2A%20T)
![Force = 0.0629m * 0.075N/m](https://tex.z-dn.net/?f=Force%20%3D%200.0629m%20%2A%200.075N%2Fm)
Darker and lighter dis would be the answer
We have to remember a point , which is ' the cart or spring rest on a smooth horizontal track ' , i.e., any frictional force doesn't take place.
<u>Explanation:</u>
a) According to the question the cart is pulled to position A and released, i.e., the velocity of the cart at A initially (say time,t=0) is 0 m/s ,then moves toward position E, where it reverses direction and returns again to position A , in the 2nd phase cart moves along A to E , the cart's velocity increase and again goes to zero at point E and again change the direction, hence
( File has been attached)
b) Let's , the distance between two consecutive points is x meter and the spring constant is k N.m
c) ( File has been attached)
d) Movinf Right
e) Moving left
