A dog's eye would be an organ.
Answer:
The speed is 0.97 c.
Explanation:
Given that,
Dilated time t'= 50.0 years
Rest time t = 13.0 years
We need to calculate the speed
Using formula of time dilation
Where, t' = change in time
t = rest time
v = velocity
c = speed of light
Put the value into the formula
Hence, The speed is 0.97 c.
The shutter speed that should be used if the lens is changed to f/4.0 is; Choice D: 1/500 s.
The relationship between the shutter speed and the focal ratio is an inverse relationship.
Ratio of Areas = 5.6²/4²
Since; T1A1 = T2A2
- T2 = 250 × 2 = 500 seconds
In essence; when the focal ratio is reduced as in this case; from f/5.6 to f/4.0; the shutter speed is increased.
Ultimately, the shutter speed of the camera in discuss increases to; 1/500 s.
