Answer:
The acceleration of the wallet is 
Explanation:
Given that,
Radius of purse r= 2.30 m
Radius of wallet r'= 3.45 m
Acceleration of the purse 
We need to calculate the acceleration of the wallet
Using formula of acceleration

Both the purse and wallet have same angular velocity








Hence, The acceleration of the wallet is 
continents, paleoclimate indicators, truncated geologic features, and fossils:D
Answer:
The angle it subtend on the retina is
Explanation:
From the question we are told that
The length of the warbler is 
The distance from the binoculars is 
The magnification of the binoculars is 
Without the 8 X binoculars the angle made with the angular size of the object is mathematically represented as



Now magnification can be represented mathematically as

Where
is the angle the image of the warbler subtend on your retina when the binoculars i.e the binoculars zoom.
So

=> 

Generally the conversion to degrees can be mathematically evaluated as
