Answer:
The answer to this question is 1 * 10g /mole = 10
Explanation:
From the question given, the first step to take is to find the weight of a 10g rubber band.
Now,
The molecular weight of rubber band , tires the primary chains may have molecular weights is of order of 1 x 10 g/
Therefore it is 1 * 10g/mole =10

Answer:
Velocity components


For Acceleration components;



Explanation:
We are given:


We first need to find the radial position r of washer in x-y plane.
Therefore

r = 500 mm
To find length along direction OA we have:

Therefore, the radial and vertical components of velocity will be given as:


Where Q is the angle between OA and vector r.
Therefore,


• 
• 
The radial and vertical components of acceleration will be:


Therefore we have:
• 
•
