Answer:
The angular magnification is 
Explanation:
From the question we are told
The focal length is 
The near point is 
The angular magnification is mathematically represented as
Substituting values
Given;
redistivity =1.68/100000000W.m
diameter =0.40in
=0.01016m
length =1m
resistance =?
redistivity =resistance×area/lenght
restance=resistivity × length /area
so, resistance =1.6535/1000000 ohmn
This isn’t anything related to physics dude
Answer:
(5) It depends on whether the collision was elastic or inelastic.
Explanation:
Due to the absence of external forces and the fact that masses and initial velocities are known, it is needed to determine if collision is elastic or inelastic. If collision is inelastic, the Momentum Principle is sufficient to calculate final momentum, but if it is elastic, the Momentum Principle should be complemented with the application of the Energy Principle.
Hence, the correct answer is (5).
