Answer:
 the refracted rays neither converge nor diverge. After refracting, the light rays are traveling parallel to each other and cannot produce an image.

Answer:
T = 4 sec / 2 = 2 sec      period of revolution
S = 2 pi R = 2 * pi * 1.75 m = 11 m
V = S / T = 11 m / 2 sec = 5.5 m/s       speed of object
 
        
             
        
        
        
C and d have the same amount of protons and electrons
        
             
        
        
        
Answer:
0.0196 j
Explanation:
i) The formula for kinetic energy is as follows: 0.5*m*v^2
ii) Since we have all the values all that's left is to plug them into the equation
iii) First, WE MUST, Convert grams into kgs as this is the SI unit of mass so 2.45/1000
iv) All that's left now is to plug it into the equation so:
0.5* (s.45/1000)*(4^2)
v) Lastly we add the unit joules at the end as we're talking about energy
Hope this was useful! :)
 
        
             
        
        
        
Answer:
a)
b)
Explanation:
a) Let's use the constant velocity equation:

- v is the speed of the muon. 0.9*c 
- c is the speed of light 3*10⁸ m/s


b) Here we need to use Lorentz factor because the speed of the muon is relativistic. Hence the time in the rest frame is the product of the Lorentz factor times the time in the inertial frame.


v is the speed of muon (0.9c)
Therefore the time in the rest frame will be:



No we use the value of Δt calculated in a)

I hope it helps you!
